[0063] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0064] like Figures 1 to 19 As shown, the cutting tool testing system of this embodiment includes a test bench 100, a spray system 600, a dust removal chamber 200, a measurement and control system 300, and a dust collection system.

[0065] The test bench 100 includes a mounting plate 9, a specimen box 10, and multiple loading drives. The mounting plate 9 is located above the specimen box 10 and is used to mount the cutting blade 800. The specimen box 10 is used to hold the cutting medium and has an open top. The multiple loading drives are used to drive the relative movement of the mounting plate 9 and the specimen box 10 so that the operating cutting blade 800 can cut the cutting medium in the specimen box 10.

[0066] For example, the test bench 100 can be a frame structure, the specimen box 10 can be installed at the bottom of the test bench 100, the mounting plate 9 can be assembled on the drive end of a portion of the load drive, and the cutting tool 800 can be detachably installed on the mounting plate 9 by bolts or the like. The specimen box 10 can be installed on the drive end of another portion of the load drive. In use, the specimen box 10 can be moved by a portion of the load drive, and the cutting tool 800 can be moved by another portion of the load drive, so that the cutting tool 800 can move according to the displacement law under actual working conditions and achieve the cutting of the cutting medium, which can be coal or rock.

[0067] The spray system 600 includes a spray pump and a nozzle. The nozzle faces the cutting tool 800 and is used to spray and cool the cutting tool 800. The spray pump is used to deliver coolant to the nozzle. For example, Figure 1As shown, the spray system 600 may also include a storage tank, which can be located on the right side of the test bench 100. The storage tank is used to store coolant, which can be water. The nozzle can be fixed on the test bench 100 and can be directly opposite the cutting tool 800. The nozzle can be connected to the storage tank through a pipe, and the spray pump can be installed on the pipe. The spray system 600 can achieve water cooling and lubrication of the cutting tool 800 during operation, thus providing a protective effect.

[0068] The dust removal chamber 200 includes a dust removal guide rail, a moving chamber, and a dust removal drive. The dust removal guide rail is located on the ground. The moving chamber is slidably mounted on the dust removal guide rail. The dust removal drive is connected to the moving chamber and is used to drive the moving chamber to extend and retract along the dust removal guide rail so that the moving chamber can cover the outer periphery of the test bench 100.

[0069] Specifically, two dust collection guide rails can be provided, each extending along the front-to-back direction and spaced apart in the left-to-right direction. The dust collection chamber 200 can include a fixed chamber and a movable chamber, wherein the fixed chamber can be located behind the movable chamber. The movable chamber can include a movable frame and a sealing cloth covering the outer periphery of the movable frame. The rear end of the movable frame can be connected to the fixed chamber, and the front end of the movable frame can be slidably mounted on the two dust collection guide rails. The dust collection drive can be a screw drive mechanism, which can include a motor and a screw. The movable frame can be slidably mounted on the dust collection guide rails, the screw can be threadedly mounted to the movable frame, and the motor can be connected to the screw.

[0070] In use, the motor drives the lead screw to rotate. The threaded engagement between the lead screw and the moving frame allows the moving frame to extend and retract along the dust removal guide rail. This allows the moving chamber to completely or completely cover the test bench 100. It should be noted that the sealing cloth can be fixed to the moving frame, and the sealing cloth can extend and retract synchronously with the moving frame.

[0071] Optionally, the dust removal chamber 200 may also be equipped with a roller shutter door, an electrical control box, a dry recycling cabinet, etc.

[0072] like Figure 1 As shown, the control part of the measurement and control system 300 (an industrial computer, which can be equipped with triaxial force measurement software to detect the cutting resistance and frequency of the hobbing cutter or cutting teeth) can be located on the right side of the dust removal chamber 200. The measurement and control system 300 includes a camera and a microscope. The camera can be an infrared high-speed camera. The camera can be installed in the dust removal chamber 200 and arranged facing the cutting tool 800. The camera is used to record pictures and / or videos of the cutting process, so that the process of the cutting medium (rock) collapse, dust generation, and heat transfer changes can be analyzed and studied.

[0073] The microscope can be an electron microscope, and the lens of the microscope can be installed in the dust removal chamber 200. The microscope can be used to observe and analyze the friction and wear of the cutting tool 804, thereby obtaining relevant data on the wear of the cutting tool 800 and providing support for the selection of materials for the cutting tool 800.

[0074] The measurement and control system 300 may also include a particle size analyzer, which can perform sieving and particle size analysis on the intercepted medium.

[0075] The dust collection system includes a dust collector fan and a filter bag. The inlet of the dust collector fan is connected to the dust collection chamber 200. The filter bag is used to store dust, and the dust collector fan is used to suck the dust in the dust collection chamber 200 into the filter bag to avoid obstructing the measurement and control system 300. Specifically, the filter bag can be fixed to the outside of the dust collection chamber 200, and the dust collection chamber 200 and the filter bag can be connected by a rigid pipe, on which the dust collector fan can be installed. During the cutting test, the dust collector fan can collect the large amount of dust generated during the cutting of the rock specimen, thereby reducing the harm to operators and the environment caused by the test, and also reducing the adverse effects of the generated dust on the shooting effect of infrared high-speed cameras, etc.

[0076] The cutting tool testing system of this invention can simulate the cutting process by moving the mounting plate 9 and the test specimen box 10 through multiple loading drives. The simulation process can better match the real working conditions, thereby ensuring the effectiveness of the test.

[0077] Secondly, by installing a dust collection system in the dust collection chamber 200, the chamber can block dust and noise, thereby reducing the impact on operators and improving the operating environment. The dust collection system can collect dust in a timely manner, preventing dust from spreading and further improving the operating environment.

[0078] In addition, because the dust collection system can promptly remove dust, ensuring the clarity of the dust removal chamber 200, the measurement and control system 300 can collect the corresponding data more accurately, thereby ensuring the accuracy of the test results.

[0079] In some embodiments, the multiple loading drives include a vertical drive 5, a horizontal drive 8, and a longitudinal drive 6. The test bench 100 also includes a base 1, a support platform 2, multiple columns 3, and a moving platform 4.

[0080] like Figure 2 and Figure 3As shown, multiple columns 3 are provided on the base 1 and arranged at intervals along the circumference of the base 1, and the multiple columns 3 enclose the working space. For example, there can be four columns 3, which can be set at the four corners respectively. Each column 3 extends roughly in the vertical direction, and the bottom end of each column 3 can be connected and fixed to the base 1 by welding, fasteners or other means. At this time, the working space is the rectangular space enclosed by the four columns 3.

[0081] like Figures 2 to 5 As shown, the support platform 2 can be a rectangular plate, and it can be fixed to the top of multiple columns 3 by welding, fasteners, or other methods. Figure 6 and Figure 7 As shown, the vertical drive 5 can be a hydraulic telescopic cylinder. The vertical drive 5 can be fixed at the center of the support platform 2, and the vertical drive 5 extends generally in the vertical direction.

[0082] The mobile platform 4 can also be roughly rectangular. The mobile platform 4 is installed in the work space and can be slidably assembled with at least part of the column 3. The top of the mobile platform 4 can be connected to the vertical drive 5. The mobile platform 4 can be adjusted up and down by extending and retracting the vertical drive 5.

[0083] The mounting plate 9 is movably positioned below the moving platform 4. The lateral drive 8 is located on the moving platform 4, connected to the mounting plate 9, and used to drive the mounting plate 9 to move laterally. For example, ... Figure 11 As shown, the mounting plate 9 can be a rectangular plate, and it can be slidably mounted on the bottom side of the mobile platform 4 along the left and right directions. The lateral drive 8 can be a hydraulic telescopic cylinder or an electric push rod. The lateral drive 8 can be fixed to the bottom side of the mobile platform 4 by fasteners, and the drive end of the lateral drive 8 can be connected and fixed to the mounting plate 9. The left and right positions of the mounting plate 9 can be adjusted by extending and retracting the lateral drive 8.

[0084] The specimen box 10 is movably mounted on the base 1 and located below the mounting plate 9. A longitudinal drive 6 is mounted on the base 1, connected to the specimen box 10, and used to drive the specimen box 10 to move longitudinally. For example, as... Figure 9 and Figure 10 As shown, the specimen box 10 can be a rectangular box, and the longitudinal drive 6 can be a hydraulic telescopic cylinder. The longitudinal drive 6 can be mounted on the base 1 and extend along the front-to-back direction. The specimen box 10 can be fixed to the drive end of the longitudinal drive 6. In use, the specimen box 10 can be moved back and forth by the longitudinal drive 6.

[0085] In some embodiments, the vertical drive 5, the horizontal drive 8, and the longitudinal drive 6 are all equipped with a detection module, which includes at least one of the following: a load sensor, a displacement sensor, a speed sensor, and a torque sensor.

[0086] For example, such as Figure 6 As shown, the vertical drive 5 can be equipped with a vertical load sensor 51, which can be installed between the bottom of the vertical drive 5 and the moving platform 4. The magnitude of the driving force applied by the vertical drive 5 can be monitored by the vertical load sensor 51.

[0087] Optionally, such as Figure 6 As shown, the vertical drive 5 can also be configured with a spherical self-aligning module 52. The spherical self-aligning module 52 can be installed between the vertical load sensor 51 and the moving platform 4. The spherical self-aligning module 52 can be a spherical self-aligning bearing or other spherical self-aligning device, thereby effectively eliminating the influence of lateral or longitudinal movement on the lateral drive 8 and the detection module.

[0088] Specifically, the vertical drive 5 mainly consists of a vertical servo cylinder, a ball joint, and a 1000kN load sensor. The cutting depth of the rotary cutting device is controlled by the displacement sensor of the vertical servo cylinder, and the radial load of the rotary cutting device is controlled by the 1000kN load sensor of the vertical drive 5.

[0089] For example, such as Figure 11 As shown, the lateral drive 8 can be equipped with a lateral displacement sensor 84, specifically a Hall effect displacement sensor, a photoelectric displacement sensor, etc. The lateral displacement sensor 84 can include a fixed part and a moving part. The fixed part can be fixed to the bottom side of the moving platform 4, and the moving part can be fixed to the mounting plate 9. When the mounting plate 9 moves, the relative position of the fixed part and the moving part will change. By this position change, the moving position of the mounting plate 9 can be monitored, and thus the position adjustment control of the cutting tool 800 on the mounting plate 9 can be realized.

[0090] Specifically, the transverse drive 8 mainly consists of a servo motor, a 200kN load sensor, a guide transmission platform, a lead screw pair, a linear guide rail, and four sets of guide ball bearing sliders. The cutting width of the rotary cutting device is controlled by the encoder of the servo motor, and the axial load of the rotary cutting device is measured by the 200kN load sensor of the transverse linear feed device.

[0091] For example, a sensor bracket is connected to the lower part of the longitudinal drive 6 by screws. The magnetic displacement sensor can be fixed inside the sensor bracket by screws and mounting clamps, thereby enabling displacement detection of the longitudinal drive 6.

[0092] Specifically, the longitudinal drive unit 6 mainly consists of a longitudinal loading cylinder, a 400kN load sensor, a ball joint, a bearing plate, a shear box, a longitudinal mounting base, a base, a feed seat, and a protective cover. The longitudinal loading cylinder pushes the shear box to move longitudinally along the heavy-duty linear guide rail, and the tangential load of the roller cutting teeth in the cutting device is detected by the 400kN load sensor housing.

[0093] It is understood that in some other embodiments, the cutting tool 800 may be equipped with a cutting device position and cutting depth (vertical cylinder displacement) displacement sensor; a drum speed (converted into cutter head linear velocity) sensor, a drum torque sensor, etc. Through the sensors of each detection module, signal acquisition, amplification, A / D conversion, data processing, etc. can be realized, and then the changes of various parameters of the test bench 100 can be displayed in real time.

[0094] The cutting tool testing system may also include a control and display module, which can be a fully digital multi-channel servo controller capable of controlling normal pressure, depth of cut (displacement), drum speed, and torque; it can also achieve closed-loop control of parameters such as horizontal longitudinal displacement (speed) and horizontal transverse feed displacement (speed). It can perform single-channel control or multi-channel coordinated control tests.

[0095] The host computer can be a computer, and the computer control and management software can be based on a Windows platform. Users can select test items and set test parameters through the computer interface, and the test process can be completed automatically or semi-automatically. The computer screen displays various parameters and curves in real time. Test data is automatically saved and can be imported into programs such as Word and Excel for further processing.

[0096] In some embodiments, the cutting tool testing system includes a hydraulic system 500, which includes a plurality of pump units, each pump unit being connected to one of the vertical drive 5, the horizontal drive 8, the longitudinal drive 6, and the cutting tool 800 and used to achieve independent driving of the vertical drive 5, the horizontal drive 8, the longitudinal drive 6, and the cutting tool 800.

[0097] Specifically, the hydraulic system 500 may include a combined hydraulic pump station, a vertical (normal pressure) cylinder pump motor unit, a stone shaft moving slide horizontal longitudinal feed pump motor unit, a tool holder horizontal transverse feed motor, a drum power unit pump motor unit, an oil tank, an oil cooler, and flexible and rigid rubber hoses, etc.

[0098] The hydraulic system 500 adopts a combined hydraulic station with a pump-and-circuit oil supply mode. Each oil pump motor unit (pump unit) can be controlled independently, allowing for flexible selection of one or more pump units to operate according to the test requirements, saving energy and reducing system heat generation while meeting test needs.

[0099] Optionally, the hydraulic system 500 may also be equipped with a pressure sensor, a temperature sensor, a level indicator, and an alarm device. The hydraulic system 500 may also be equipped with a filter device. During operation, the oil suction, pressure oil, and return oil of the hydraulic system 500 can all pass through the filter device, thereby ensuring the cleanliness of the hydraulic oil and the long-term stable operation of the servo system.

[0100] In some embodiments, when the vertical drive 5, the horizontal drive 8, and the longitudinal drive 6 are hydraulic telescopic cylinders, the hydraulic system 500 can also be equipped with a self-depressurization function. For example, a pressure relief valve can be installed on the corresponding hydraulic pipeline. Taking the vertical drive 5 as an example, during the test, due to the shape of the cutting teeth of the cutting tool 800 and the discontinuous arrangement on the roller (hob), the cutting tool 800 and the cylinder will be impacted. When the impact load exceeds the set maximum normal pressure, the vertical cylinder will automatically depressurize for protection, thereby protecting the tool 804 from abnormal damage.

[0101] In some embodiments, the mobile platform 4 is provided with a plurality of assembly slots 43, which are arranged at intervals along the circumference of the mobile platform 4. A plurality of columns 3 are fitted into the plurality of assembly slots 43 in a corresponding manner. Each column 3 is provided with a vertical guide rail 31, which extends along the column 3. Each assembly slot 43 is provided with a first mating part 41 and a second mating part 42. The first mating part 41 is rolled or slidably mated with one side of the vertical guide rail 31, and the second mating part 42 is rolled or slidably mated with the other side of the vertical guide rail 31.

[0102] For example, such as Figure 2 As shown, each column 3 can be equipped with a vertical guide rail 31. The cross-section of the vertical guide rail 31 can be triangular or rectangular, such as... Figure 8 As shown, the mobile platform 4 can be roughly rectangular. Each of the four corners of the mobile platform 4 can be provided with an assembly slot 43. The assembly slot 43 can be a rectangular slot. Each assembly slot 43 includes two vertically arranged slot walls. The first mating part 41 can be installed on one of the slot walls, and the other mating part can be installed on the other slot wall.

[0103] It should be noted that both the first mating part 41 and the second mating part 42 may include a rolling guide block (similar to a roller). Thus, the first mating part 41 and the second mating part 42 can respectively achieve rolling engagement with the vertical guide rail 31, which on the one hand facilitates the upward and downward sliding adjustment of the mobile platform 4, and on the other hand enhances the limiting and constraint effect, prevents the mobile platform 4 from rotating in the working space, and improves the stability of movement.

[0104] In some embodiments, such as Figure 9 As shown, a workbench 7 is provided on the base 1, and two support frames 11 are provided on the base 1. The two support frames extend along the longitudinal direction (front and back direction) of the base 1 and are arranged at intervals along the transverse direction (left and right direction) of the base 1. Each support frame 11 can be provided with a longitudinal guide rail 12 on its top. The longitudinal guide rail 12 can be fixed to the support frame 11 by bolts.

[0105] like Figure 13As shown, the worktable 7 is provided with a longitudinal slider 71. There can be two longitudinal sliders 71. The two longitudinal sliders 71 can be arranged at intervals in the left and right directions. Each longitudinal slider 71 can slide and engage with the corresponding longitudinal guide rail 12. That is, the worktable 7 is slidably assembled with the two support frames 11 through the longitudinal sliders 71 and the longitudinal guide rail 12.

[0106] Optionally, such as Figure 13 As shown, the base 1 can be fixed to the foundation by anchor bolts 14.

[0107] like Figure 10 As shown, the specimen box 10 is positioned above the workbench 7. The specimen box 10 can be detachably mounted on the workbench 7 using fasteners such as screws. The cylinder of the longitudinal drive 6 can be connected and fixed to the workbench 7, and the longitudinal drive 6 can be fitted between two support frames 11. This provides a protective effect.

[0108] like Figure 13 As shown, a shield 72 can be connected between the worktable 7 and the base 1. The shield 72 is retractable and can be extended by pulling when the worktable 7 moves to provide shielding and protection. Specifically, the shield 72 may include a stainless steel protective cover located above the longitudinal drive 6 and protective baffles located on the left and right sides of the worktable 7. When the worktable 7 moves under the action of the longitudinal drive 6, the stainless steel protective cover and protective baffles can be extended and retracted with the back and forth movement of the worktable 7, so as to always provide a protective effect.

[0109] Optionally, the shield 72 may also include a top plate, which can be fixed to the outermost side of the base 1 by screws or the like, so that it can cooperate with the stainless steel protective cover and protective baffle to form an overall protection, avoiding the longitudinal drive 6 from being disturbed by the debris and sewage generated during the cutting process.

[0110] In some embodiments, the longitudinal drive 6 is a hydraulic telescopic cylinder, equipped with a first servo valve group and a second servo valve group. The feed flow rate of the first servo valve group is less than that of the second servo valve group. The first servo valve group is used to achieve small-scale driving of the longitudinal drive 6, and the second servo valve group is used to achieve large-scale driving of the longitudinal drive 6. Thus, in the rotary cutting test mode, the feed of the cutting medium in the forward and backward directions can be controlled by the small-flow servo valve (first servo valve group), thereby achieving precise control.

[0111] In some embodiments, such as Figures 2 to 4As shown, the base 1 is provided with multiple reinforcing plates 13, which are correspondingly positioned within the angle formed by the multiple columns 3 and the base 1. One vertical edge of each reinforcing plate 13 is connected to a column 3, and the bottom edge of each reinforcing plate 13 extends longitudinally along the base 1. Therefore, the reinforcing plates 13 can support the columns 3 in the front-back direction, ensuring high structural strength of the columns 3 in the front-back direction and meeting the adjustment requirements of the longitudinal drive 6.

[0112] Optionally, the reinforcing plate 13 is provided with multiple weight-reducing holes. These holes can be arranged through topology optimization design, which can ensure the structural strength of the reinforcing plate 13 while saving materials and reducing costs.

[0113] In some embodiments, such as Figure 11 As shown, the bottom of the mobile platform 4 is provided with a horizontal guide rail 83. There can be two horizontal guide rails 83. Both horizontal guide rails 83 can extend along the left and right direction and be arranged at intervals in the front and back direction. The mounting plate 9 can be provided with a horizontal slider. There can also be two horizontal sliders. The two horizontal sliders are respectively slidably assembled on the corresponding horizontal guide rails 83. That is, the mounting plate 9 is slidably assembled with the mobile platform 4 through the horizontal guide rails 83 and the horizontal sliders.

[0114] The lateral drive 8 includes a motor 81 and a lead screw 82. The motor 81 can be a hydraulic motor, which can be controlled by a hydraulic system 500. The lead screw 82 is rotatably mounted below the mounting plate 9 and threadedly engaged with the mounting plate 9. For example, the bottom of the moving platform 4 can be provided with two bases, and the lead screw 82 can be rotatably mounted on the two bases with bearings. The mounting plate 9 can be provided with threaded holes, and the lead screw 82 can be threadedly mounted on the mounting plate 9. The motor 81 can be connected and fixed to the end of the lead screw 82 through a coupling. In use, the motor 81 can drive the lead screw 82 to rotate, thereby realizing the adjustment of the left and right position of the mounting plate 9.

[0115] Optionally, such as Figure 12 As shown, the top of the vertical drive 5 can be connected to the pipe joint via a sealing ring, and the support platform 2 can be connected and fixed to the cylinder boss of the vertical drive 5 via bolts. The moving platform 4 can be equipped with multiple lifting lugs 21 (lifting screws), which facilitate the lifting of the moving platform 4, thereby facilitating the movement of the test bench 100.

[0116] In some embodiments, such as Figure 14As shown, the specimen box 10 includes multiple annular box sections 101, which can be rectangular. These annular box sections 101 are stacked sequentially along the vertical direction to form the specimen box 10, and adjacent annular box sections 101 can be detachably connected and fixed with bolts. Therefore, during the test, the height of the specimen box 10 can be adjusted to match the height of the cutting medium; that is, as the height of the cutting medium decreases, the upper annular box sections 101 can be disassembled sequentially.

[0117] like Figure 15 As shown, each annular box 101 is provided with a lifting member 102 on its outer periphery. The lifting member 102 can be a lifting eye bolt. Multiple lifting members 102 can be provided. Multiple lifting members 102 can be arranged at intervals along the circumference of the annular box 101. The setting of the lifting member 102 facilitates the lifting of the annular box 101, thereby facilitating installation and disassembly.

[0118] Optionally, such as Figure 15 As shown, each annular box 101 may be provided with a tongue and groove structure. The tongue and groove structure can realize the insertion and mating of two adjacent annular box 101, thereby enhancing the stability and strength of the structure.

[0119] In some embodiments, the cutting tool testing system further includes a sewage system 700, which includes a sedimentation tank and a waste bin. The sedimentation tank is used to collect the coolant from the spray system 600, and the waste bin is used to collect the cutting media waste (stone chips, etc.) after cutting, enabling resource reuse.

[0120] In some embodiments, the cutting tool testing system further includes a power supply system 400, which provides power to the cutting tool testing system. For example, the power supply system 400 may include a distribution cabinet, which may be equipped with an air switch to provide protection.

[0121] In some embodiments, such as Figure 16 and Figure 17 As shown, the cutting tool 800 includes a first frame 801, a cutting drive 802, a cutting tool 800, a first coupling 805, a second coupling 806, and a tool sensor 807. The first frame 801 is detachably mounted below the mounting plate 9. The cutting drive 802 and the second frame 803 are located on the first frame 801. The tool 804 is rotatably mounted in the second frame 803. The first coupling 805, the tool sensor 807, and the second coupling 806 are connected between the cutting drive 802 and the second frame 803. The first coupling 805 is connected between the cutting drive 802 and the tool sensor 807, and the second coupling 806 is connected between the shafts of the tool sensor 807 and the tool 804.

[0122] Specifically, the cutting drive 802 can be a roller motor, the first coupling 805 can be a spline-double key coupling, the second coupling 806 can be a double key coupling, and the tool sensor 807 can be a torque sensor.

[0123] The roller motor drives the roller to rotate through two sets of couplings and a torque and speed sensor, and controls the roller's rotation speed and torque through the torque and speed sensor.

[0124] The outer side of the roller motor can be connected to the hydraulic system 500 via mounting pipe fittings and flanges. The upper part of the first frame 801 can be bolted to the transition plate 808 and mounting plate 9. One side of the first frame 801 can be bolted to and fixed to the roller motor. The output splined shaft of the roller motor is connected to the inner splined end of the first coupling 805 for torque transmission. The keyed side of the first coupling 805 is connected to the tool sensor 807, which is bolted to the torque sensor bracket. The upper part of the torque sensor bracket can be bolted to the transition plate 808 and mounting plate 9. The other end of the tool sensor 807 is connected to the second coupling 806. The other end of the second coupling 806 can be connected to the shaft of the tool 804.

[0125] The cutting tool 800 may include a tool 804 and a second holder 803. The tool 804 is rotatably mounted in the second holder 803 via two shafts, and the tool 804 is connected to the corresponding shaft via two flat keys. A single-row tapered roller bearing and an end cap can be mounted on the second holder 803. The shaft of the tool 804 is rotatably mounted within the single-row tapered roller bearing and the end cap, wherein the outer end cap can be fixed with a plug. This structure enables the driving of the cutting tool 800 and the detection of its torque.

[0126] In some embodiments, such as Figure 6 and Figure 19 As shown, the cutting tool 800 can be a hobbing cutter 804. In some other embodiments, such as... Figure 7 and Figure 18 As shown, the cutting tool 804 can also be a cutting drum type cutting tool 804. This allows for the detection of several different types of cutting tools 800.
