Description

Technical Field

[0001] This disclosure relates to the field of machining center technology, and more specifically to a calibration component. Background Technology

[0002] When performing automated machining in a machining center (MCT), it is usually necessary to set various tools of different specifications in the automatic tool changer to a uniform extension length to ensure precise coolant spraying and consistency of machining reference. Current technology generally adopts a manual method, with operators using tools such as calipers and tool setters for visual setting. However, this traditional method has significant drawbacks. First, the operation process is cumbersome, and tool setting is too time-consuming, seriously affecting production preparation efficiency. Second, the setting accuracy heavily relies on the operator's experience and subjective visual judgment, making it difficult to guarantee a high degree of consistency between different tools, resulting in low repeatability. This lack of accuracy and consistency ultimately leads to problems such as unstable cooling effect and reduced workpiece machining quality, which can no longer meet the manufacturing industry's requirements for high efficiency and high precision.

[0003] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0004] In view of the above problems, this disclosure provides a calibration component that solves the problems of low efficiency, low accuracy and poor consistency caused by the reliance of operators to visually set tools using measuring tools in the existing traditional tool installation.

[0005] One aspect of this disclosure provides a calibration element for calibrating the mounting position of a cutting tool on a tool holder. The calibration element includes: a sleeve mechanism having a measuring part and a sleeve hole extending along a first direction, the measuring part being located on one side of the sleeve hole in the first direction, and the sleeve mechanism being able to be fitted onto the outer periphery of the tool holder based on the sleeve hole; and a stop portion movably disposed on the measuring part along the first direction, wherein, in the state where the sleeve mechanism is fitted onto the tool holder and the stop portion is positioned on the measuring part, the cutting tip of the cutting tool can abut against the stop portion to calibrate the protrusion length of the cutting tip relative to the tool holder.

[0006] In some exemplary embodiments, the sleeve mechanism includes a sleeve seat and a limiting flange, the sleeve hole is formed in the sleeve seat, and the limiting flange is formed at one end of the sleeve seat away from the measuring tool portion. The limiting flange is used to abut against the calibration surface so that the bottom of the sleeve mechanism and the bottom of the tool holder are on the same plane.

[0007] In some exemplary embodiments, the measuring tool is connected to one end of the sleeve seat in the first direction, and the measuring tool extends from the sleeve seat along a direction parallel to the central axis of the sleeve hole and away from the sleeve seat.

[0008] In some exemplary embodiments, the stop portion includes a connected stop block and a locking member, the locking member being movably disposed on the measuring portion along the first direction and capable of being locked at any position on the measuring portion to position the stop block, and the end of the stop block facing the sleeve seat forming an abutment surface for abutting the cutting head.

[0009] In some exemplary embodiments, the stop block protrudes from the locking member toward the central axis of the sleeve hole.

[0010] In some exemplary embodiments, the measuring tool is provided with a guide groove that extends in a direction parallel to the central axis of the sleeve hole, and the locking member is movably inserted into the guide groove and can be locked in any position of the guide groove.

[0011] In some exemplary embodiments, the locking member includes a bolt structure and a knob structure. The bolt structure passes through the guide groove, one end of the bolt structure is connected to the knob structure, and the other end of the bolt structure is threadedly engaged with the stop block, which can drive the stop block to position and abut against the measuring tool part.

[0012] In some exemplary embodiments, the surface of the measuring tool facing the central axis of the sleeve hole is a concave arc surface, and the curvature of the concave arc surface is consistent with the curvature of the inner surface of the sleeve hole.

[0013] In some exemplary embodiments, the measuring tool is integrally formed with the sleeve seat, and the measuring tool is provided with a plurality of length graduations at intervals along the central axis parallel to the sleeve hole and in a direction away from the sleeve seat.

[0014] Another aspect of this disclosure provides a tool mounting method using the aforementioned calibration component, comprising: moving the stop portion along the measuring tool portion to a preset calibration position and locking it; fitting the sleeve mechanism onto the tool holder and aligning the bottom plane of the sleeve mechanism with the bottom plane of the tool holder; adjusting the protruding length of the tool tip relative to the tool holder until the tool tip abuts against the stop portion; and fixing the tool tip inside the tool holder.

[0022] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0023] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0024] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0025] When using expressions such as "at least one of A, B, and C," the meaning should generally be interpreted according to the understanding of someone skilled in the art. For example, "a system having at least one of A, B, and C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C. Similarly, when using expressions such as "at least one of A, B, or C," the meaning should generally be interpreted according to the understanding of someone skilled in the art. For example, "a system having at least one of A, B, or C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C.

[0026] In modern precision manufacturing, especially in the metal cutting industry, the application of automated CNC equipment such as machining centers (MCTs) is quite widespread. A key advantage of these machines is their automatic tool change (ATC) function, which allows them to automatically change dozens or even more tools in a single setup to complete various complex machining operations such as drilling, milling, tapping, and boring, thereby achieving continuous and efficient production. During these machining processes, especially in high-speed cutting or machining of difficult-to-machine materials, a large amount of cutting heat is generated. Therefore, it is essential to adequately cool the contact area between the tool and the workpiece to suppress temperature rise, ensure machining accuracy, extend tool life, and improve the surface quality of the workpiece. For this purpose, machining centers are typically equipped with cooling systems that precisely deliver coolant (usually a mixture of water and cutting oil) to the cutting point through nozzles. However, because the various tools stored in the automatic tool changer have different specifications, diameters, and total lengths, and the coolant nozzle positions on the machine tool are usually fixed or only slightly adjustable during a single machining task, the overall performance of these machines is limited. Therefore, to ensure that the coolant is accurately sprayed onto the machining points of different tool tips after each tool change, a technical requirement arises: during the tool mounting process, the protrusion height (i.e., extension length) of each tool tip relative to the tool holder's reference surface must be precisely set to the same standard value. Only in this way can the stability and consistency of the cooling effect be guaranteed throughout the entire automated machining process.

[0027] To address the need for standardized setting of tool protrusion length, the industry currently predominantly employs manual adjustment. Operators typically use independent measuring tools such as height gauges, calipers, and depth gauges, or operate on a dedicated tool setting device, when setting the tool. In practice, the operator first places the tool into the clamping hole of the tool holder, then measures it using measuring tools, visually compares the readings, and repeatedly and subtly taps or moves the tool, taking another measurement. This iterative process of "adjustment-measurement-readjustment" needs to be repeated multiple times until the tool protrusion length meets the preset standard. This traditional method has significant drawbacks: First, its efficiency is extremely low. In production scenarios requiring a large number of tools, meticulous manual tool setting for each tool consumes a significant amount of auxiliary time, becoming a bottleneck in the production preparation stage and directly impacting the machining center's uptime and overall production efficiency. Second, the accuracy and consistency of the setting heavily rely on the operator's personal experience and skill level. Different operators, or even the same operator setting the tool height at different times, can introduce human observation and judgment errors, leading to inconsistent tool height settings. This inconsistency not only affects cooling efficiency but can also cause quality issues such as dimensional deviations in precision machining. Therefore, this meticulous, slow-paced manual operation method is no longer sufficient to meet the urgent demands of modern manufacturing for high efficiency, high precision, and high standardization.

[0028] As one aspect of the embodiments of this disclosure, such as Figure 1 and Figure 2As shown, a calibration component is provided for calibrating the mounting position of a cutting tool 100 on a tool holder 200. The calibration component includes: a sleeve mechanism 300 having a measuring part 320 and a sleeve hole 310 extending along a first direction F. The measuring part 320 is located on one side of the sleeve hole 310 in the first direction F. The sleeve mechanism 300 can be sleeved on the outer periphery of the tool holder 200 based on the sleeve hole 310; and a stop part 400 movably disposed on the measuring part 320 along the first direction F. In the state where the sleeve mechanism 300 is sleeved on the tool holder 200 and the stop part 400 is positioned on the measuring part 320, the cutting tip of the cutting tool 100 can abut against the stop part 400 to calibrate the protrusion length of the cutting tip relative to the tool holder 200. In some specific embodiments, the calibration component provided in this disclosure, through the sleeve mechanism 300 and the stop 400 that can move and be positioned thereon, transforms the complex measurement work that originally relied on the operator's experience and visual judgment into an intuitive physical positioning process. This effectively solves the technical problems of low efficiency, unstable accuracy, and poor consistency in manual tool setting operations in the prior art. Specifically, by using this calibration component, there is no need to rely on independent calipers or height gauges for repeated "measurement-adjustment" cycles. This not only greatly shortens the preparation time of the tool 100 and improves production efficiency, but more importantly, through a fixed mechanical abutment method, it fundamentally eliminates human observation errors, ensuring that the protrusion length of each tool 100 relative to the tool holder 200 can be accurately and repeatably set to a uniform standard value. This provides a solid guarantee for the consistency of cooling effect and the stability of machining quality in subsequent automated machining processes.

[0029] In some specific embodiments, the sleeve mechanism 300 serves as the reference frame for the entire calibration component. The sleeve hole 310 formed inside the sleeve mechanism 300 is the basis for achieving precise positioning. The inner wall profile of the sleeve hole 310 is configured to fit tightly with the outer peripheral surface of the standard tool holder 200. When the sleeve mechanism 300 is fitted onto the tool holder 200, a stable and repeatable installation reference is established. The measuring part 320, connected to the sleeve hole 310 and extending along the first direction F, provides a precise movement and positioning guide for the stop part 400. Since the measuring part 320 and the sleeve hole 310 are two fixed components of the sleeve mechanism 300, their relative spatial positions are constant, ensuring the high stability of the entire measurement reference system. The stop part 400, as an adjustable length setting unit, can slide freely along the guide of the measuring part 320 in the first direction F and can be reliably locked at any desired position. In actual operation, once the sleeve mechanism 300 and the tool holder 200 are aligned to a reference, a stop 400, pre-locked in a specific position, forms a precise target endpoint in space. At this point, simply moving the tool 100 inserted into the tool holder 200 until the tool tip makes clear physical contact with the stop 400 precisely determines the protruding length of the tool 100. The entire process relies entirely on direct contact and positioning between structural components, rather than indirect visual readings, enabling rapid and accurate positioning.

[0030] like Figure 1 and Figure 2 , Figure 3As shown, in some exemplary embodiments, the sleeve mechanism 300 includes a sleeve seat 330 and a limiting flange 331. A sleeve hole 310 is formed in the sleeve seat 330, and the limiting flange 331 is formed at the end of the sleeve seat 330 away from the measuring part 320. The limiting flange 331 is used to abut against the calibration surface so that the bottom of the sleeve mechanism 300 and the bottom of the tool holder 200 are on the same plane. In some specific embodiments, in order to ensure that the reference height is absolutely consistent for each calibration operation, thereby achieving high-precision repeatable setting, the sleeve mechanism 300 consists of a sleeve seat 330 as a main body and a limiting flange 331 integrally formed or fixedly connected to its bottom end. The sleeve hole 310 is formed inside the sleeve seat 330. When the calibration component is fitted onto the tool holder 200, the lower surface of the limiting flange 331 acts as a clear physical stop surface, abutting against the calibration surface along with the bottom end face of the tool holder 200 itself. This structured hard contact ensures that the installation depth of the sleeve mechanism 300 is precisely defined, thus ensuring that the bottom plane of the sleeve mechanism 300 and the bottom plane of the tool holder 200 are strictly at the same level. In this way, the calibration component establishes a stable and error-free starting reference for subsequent length calibration. No matter how many times the tool 100 is changed or how many people operate it, the starting point for measuring the tool tip protrusion length set by the stop part 400 is always consistent. This fundamentally guarantees that all tools 100 set by this calibration component have a highly consistent protrusion length, effectively solving the accuracy problem caused by inconsistent references in the prior art.

[0031] like Figures 1 to 3 As shown, in some exemplary embodiments, the measuring tool 320 is connected to one end of the sleeve seat 330 in a first direction F. The measuring tool 320 extends from the sleeve seat 330 along a direction parallel to the central axis Z of the sleeve bore 310 and away from the sleeve seat 330. In some specific embodiments, the measuring tool 320 is firmly connected to the upper end of the sleeve seat 330 and extends away from the sleeve seat 330 in an orientation parallel to the central axis Z of the sleeve bore 310. This parallel extension ensures that the trajectory of the stop 400 moving thereon is completely consistent with the trajectory of the tool 100 axially adjusting within the tool holder 200, thereby avoiding measurement errors introduced by angular deviations. In some embodiments, the measuring tool 320 can be designed as a plate-shaped column, which provides rigidity and stability to ensure that the stop 400 does not deform or wobble during positioning and contact. In other embodiments, to adapt to different design requirements or reduce overall weight, the measuring part 320 can also be designed as a hollow tubular structure, such as a circular or square cylinder; furthermore, to further improve operational convenience, please refer to... Figure 5As shown, in some embodiments, the measuring part 320 may also be specially provided with an open window or notch. This design allows the operator's fingers or special tools to easily pass through the measuring part 320 to move the position of the tool 100 inserted into the tool holder 200 so that the tool 100 can abut against the stop part 400, or directly lock or loosen the clamping mechanism (e.g., chuck nut) inside the tool holder 200. This achieves the final fixation of the tool 100 without removing the calibration part. In some embodiments, the open window or notch extends along the first direction F.

[0032] like Figure 1 and Figure 2 , Figure 4 As shown, in some exemplary embodiments, the stop portion 400 includes a connected stop block 410 and a locking member 420. The locking member 420 is movably disposed on the measuring part 320 along a first direction F and can be locked at any position of the measuring part 320 to position the stop block 410. The end of the stop block 410 facing the sleeve seat 330 forms an abutment surface for abutting the cutting head. In some specific embodiments, the locking member 420 allows the entire stop portion 400 to slide smoothly along the guide rail of the measuring part 320, thereby allowing the operator to freely select the calibration height according to different setting requirements; when the target position is reached, the locking member 420 can fix itself and the stop portion 400 at any position of the measuring part 320 by its locking force. The stop block 410 is the final contact point for the calibration action. After the locked part 420 is precisely positioned, the abutment surface of the stop block 410 facing the sleeve seat 330 forms an immovable physical reference surface in space. The organic combination of "movable selection" and "rigid positioning" enables the calibration part to meet the setting requirements of various length specifications, while ensuring high accuracy and high reliability for each setting.

[0033] like Figure 1 and Figure 2 , Figure 4As shown, in some exemplary embodiments, the stop block 410 protrudes from the locking member 420 toward the central axis Z of the sleeve bore 310. In some specific embodiments, in order for the stop block 410 to effectively interact with the tool 100 mounted at the center of the tool holder 200, the stop block 410 is not merely attached to the locking member 420, but rather protrudes from the position of the locking member 420 toward the central axis Z of the sleeve bore 310 in a cantilevered structure, thus bridging the physical distance between the gauge section 320 and the center of the sleeve bore 310. Since the tool 100 is mounted and adjusted along the central axis Z of the sleeve bore 310, the stop block 410 needs to extend into the vertical path of the central axis Z, creating spatial interference, to ensure that its lower abutment surface is accurately positioned directly above the tool tip, so that the stop block 410 can act as an effective "ceiling," providing a clear physical blockage when the tool 100 is adjusted upwards.

[0034] like Figures 1 to 3 As shown, in some exemplary embodiments, the measuring part 320 is provided with a guide groove 321. The guide groove 321 extends in a direction parallel to the central axis Z of the sleeve hole 310. The locking member 420 is movably inserted into the guide groove 321 and can be locked in any position of the guide groove 321. In some specific embodiments, the measuring part 320 is specially provided with a guide groove 321. The extending direction of the guide groove 321 is parallel to the central axis Z of the sleeve hole 310, providing a precise linear trajectory for the movement of the locking member 420. By inserting the main body of the locking member 420 into the guide groove 321 and using the side wall of the guide groove 321 as a physical guide, the locking member 420 can be effectively prevented from deflecting or shaking during sliding, ensuring the uniformity of its movement direction, thereby improving the stability of the adjustment process and the accuracy of positioning. The engagement of the locking member 420 with the guide groove 321 allows the stop portion 400 to be moved to the desired position and reliably secured at any point within the length of the guide groove 321 by the locking member 420. In some embodiments, the guide groove 321 may be a through groove extending through the thickness of the measuring portion 320, allowing the rod-shaped portion of the locking member 420 to pass completely through. In other embodiments, the guide groove 321 may also be designed as a non-through groove or a T-slot, a structure that can engage with locking members 420 of a specific shape (such as a T-nut).

[0035] like Figure 1 and Figure 2 , Figure 4As shown, in some exemplary embodiments, the locking member 420 includes a bolt structure 421 and a knob structure 422. The bolt structure 421 passes through the guide groove 321, one end of the bolt structure 421 is connected to the knob structure 422, and the other end of the bolt structure 421 is threadedly engaged with the stop block 410, which can drive the stop block 410 to be positioned against the measuring part 320. In some specific embodiments, the shank of the bolt structure 421 passes through the guide groove 321 that extends through the thickness of the measuring part 320. One end of the bolt structure 421 is connected to the knob structure 422, which typically has a large diameter and anti-slip texture, making it easy for the operator to turn it directly by hand without the aid of any tools. The other end of the bolt structure 421 is threadedly engaged with the stop block 410. The locking principle is as follows: when the operator rotates the knob structure 422 clockwise, the bolt structure 421 screws into the stop block 410, thereby pulling the stop block 410 and the knob structure 422 closer together. This action generates a huge clamping force on both sides of the measuring part 320, causing the inner side of the stop block 410 and the inner side of the knob structure 422 (or the gasket below it) to press tightly against the surface of the measuring part 320 around the guide groove 321. The resulting friction is sufficient to firmly lock the entire stop part 400 assembly in its current position. Conversely, rotating the knob structure 422 counterclockwise quickly releases the clamping force, allowing the stop part 400 to return to its movable state. This design cleverly utilizes the self-locking and force-increasing effect of the thread to achieve stepless and reliable positioning within the guide groove 321.

[0036] like Figures 1 to 3 , Figure 6As shown, in some exemplary embodiments, the surface of the measuring part 320 facing the central axis Z of the sleeve hole 310 is a concave arc surface, and the curvature of the concave arc surface is consistent with the curvature of the inner surface of the sleeve hole 310. In some specific embodiments, the measuring part 320 is a column-shaped structure extending from one end edge of the sleeve hole 310, and its inner surface facing the central axis Z of the sleeve hole 310 is specially machined into a concave arc surface. The radius of curvature of this concave arc surface is designed to be consistent with the radius of curvature of the inner surface of the sleeve hole 310, which is equivalent to "carving out" a clearance space along the inner side of the measuring part 320 that matches the shape of the tool holder 200. The purpose of this design is that when the calibration element is fitted onto a special tool holder 200 with a flange, boss, or other diameter gradient structure above the base, the concave arc surface can provide sufficient clearance to effectively avoid physical interference between the inner side of the measuring part 320 and these protruding parts of the tool holder 200. Without this design, interference would prevent the calibration component from fully settling in, and its bottom reference surface would not align with the bottom plane of the tool holder 200, thus introducing serious calibration errors. Therefore, this concave arc surface design greatly enhances the product's versatility and compatibility, ensuring that the calibration component can be correctly and unobstructedly installed regardless of the shape of the tool holder 200, thereby guaranteeing the absolute reliability of the calibration reference.

[0037] like Figures 1 to 3 As shown, in some exemplary embodiments, the measuring tool 320 and the sleeve base 330 are integrally formed. The measuring tool 320 has multiple length graduations spaced apart along the central axis Z parallel to the sleeve hole 310 and in a direction away from the sleeve base 330. In some specific embodiments, the measuring tool 320 and the sleeve base 330 are manufactured as a single piece, for example, by precision casting or CNC milling from a single piece of metal. This fundamentally eliminates the possibility of loosening, deformation, or angular deviation between the measuring tool 320 and the sleeve base 330 due to long-term use or accidental impact, ensuring the permanent accuracy of the measurement reference. Secondly, to allow operators to set the calibration length more intuitively and quickly, the surface of the measuring tool 320 has multiple precise length graduations spaced apart along the direction parallel to the central axis Z of the sleeve hole 310, further improving work efficiency and providing clear visual guidance for standardized operations.

[0038] As another aspect of the embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, a tool mounting method is provided, using the above-mentioned calibration component, including: operations S100 to S400.

[0039] Operation S100: Move the stop 400 along the measuring tool 320 to a preset calibration position and lock it.

[0040] Operation S200: Place the sleeve mechanism 300 onto the tool holder 200 and align the bottom plane of the sleeve mechanism 300 with the bottom plane of the tool holder 200.

[0041] Operation S300: Adjust the protrusion length of the cutter head relative to the cutter holder 200 until the cutter head abuts against the stop 400.

[0042] Operation S400: Fix the tool head inside the tool holder 200.

[0043] In some specific embodiments, operation S100 is the "preset" step in the entire calibration process. According to the requirements of the machining process, the stop 400 is precisely positioned to the target length and securely locked using the scale on the measuring tool 320 or in conjunction with external calipers, thereby establishing a clear length reference on the calibration part. Operation S200 is crucial for establishing the "zero point" reference. The reliable contact between the limiting flange 331 of the sleeve mechanism 300 and the bottom of the tool holder 200 ensures absolute consistency of the measurement starting point. Operation S300 simply involves pushing the tool 100 into the tool holder 200 until a clear physical contact is felt between the tool tip and the stop 400's contact surface; the entire length setting is then complete, a process that is intuitive and unambiguous. Operation S400 clamps and fixes the tool 100 while it is stably abutted by the stop 400, effectively preventing axial displacement of the tool 100 during locking, thus reliably maintaining the calibrated precise length. Operating from S100 to S400 transforms a complex, skill-dependent task into a fast and virtually error-free standardized process, significantly improving the efficiency of production preparation and the consistency of processing quality.

[0044] As another aspect of this disclosure, a machining method utilizing a machining center is provided: First, before the start of a machining task, according to process requirements, the aforementioned calibration components are used to pre-calibrate the lengths of multiple cutting tools of different specifications required for the task (e.g., a first tool, such as an end mill; and a second tool, such as a drill bit), so that the protrusion length of the cutting tip relative to the bottom of the tool holder for each tool is precisely set to the same standard value. Then, the first tool, along with its tool holder, is mounted onto the spindle of the machining center, and the position and orientation of the coolant nozzles are adjusted to alignment in one step according to the standard protrusion length, so that the coolant sprayed from the nozzles can be precisely focused on the cutting point of the first tool tip. When the first machining operation (e.g., milling) is performed, the coolant can efficiently and continuously cool the cutting tip area where the maximum heat is generated. After the first operation is completed, the automatic tool changer of the machining center replaces the first tool and mounts the pre-calibrated second tool onto the spindle to perform the next operation (e.g., drilling). At this point, the most crucial aspect is that, since the calibrated length of the second tool's tip is exactly the same as that of the first tool, the spatial position of its cutting point is also identical to that of the first tool. Therefore, without any recalibration or position adjustment, the coolant nozzle can accurately cover the cutting point of the second tool's tip. Subsequently, regardless of how many identically calibrated tools are used in the machining process, the cooling system maintains this "adjustment-free" precise cooling capability. This completely solves the problem of unstable cooling effects and the need for repeated nozzle adjustments caused by inconsistent tool lengths, thus improving overall machining efficiency and quality stability.

[0045] The embodiments of this disclosure have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of this disclosure. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of this disclosure, and all such substitutions and modifications should fall within the scope of this disclosure.
