Abstract

This invention discloses a method and device for measuring the sharpness of a disc cutter. The method calculates the cutting attenuation coefficient of the disc cutter's edge by recording the small wedge angle radius before and after cutting the material. It also establishes curves showing the change in force and time experienced by the disc cutter as it moves along the X and Y axes while cutting the material, dividing the cutting process into three stages. The sharpness of the disc cutter is then calculated based on the work done by the disc cutter in each stage, the small wedge angle radius before and after cutting, the cutting time, the cutting length, and the hardness of the material. Compared to traditional static cutting tests, this dynamic cutting test method can more accurately obtain the sharpness of the disc cutter.

Description

Technical Field

[0001] This invention relates to the field of disc cutter machining technology, and specifically to a method and device for measuring the sharpness of a disc cutter. Background Technology

[0002] Honeycomb composite materials are widely used in the aerospace industry. These materials offer significant advantages, possessing excellent mechanical and electromagnetic properties, but require high-precision machining. Machining honeycomb materials necessitates the use of specialized disc cutters with sharp, wedge-shaped cutting edges. During high-speed cutting, disc cutters generate chips or shavings, and as the sharpness of the cutter decreases, cutting performance weakens significantly, leading to a reduction in machining quality. To obtain products with excellent machining quality and stable dimensional accuracy, the cutting edge needs to be sufficiently sharp. Therefore, testing the sharpness of disc cutters is extremely important.

[0003] Currently, the sharpness of disc cutters is mainly tested during static cutting processes. However, the machining of disc cutters involves complex movements such as feeding motion and high-speed rotation. Traditional single sharpness testing devices and methods cannot accurately obtain the sharpness of disc cutters. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the existing disc cutter sharpness testing devices and methods cannot accurately obtain the sharpness of the disc cutter, thereby providing a disc cutter sharpness measurement method.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] A method for measuring the sharpness of a disc cutter includes the following steps:

[0007] During the process of the disc cutter cutting the material, the disc cutter is driven to cut the material at a uniform speed of rotation speed n and feed speed V; the small wedge angle cutting edge radius R1 before cutting and the small wedge angle cutting edge radius R2 after cutting are recorded.

[0008] During the cutting process, the magnitude of the force F on the disc cutter is measured in real time; the Fx-t curve is established based on the relationship between the magnitude of the force Fx on the disc cutter in the X-axis direction and time t, and the Fy-t curve is established based on the relationship between the magnitude of the force Fy on the disc cutter in the Y-axis direction and time t.

[0009] Based on the variation curves of Fx-t and time Fy-t, the disc cutter cutting process is divided into the entry stage, the stable cutting stage, and the exit stage, and the entry work W1, the stable cutting work W2, and the exit work W3 are calculated respectively.

[0010] The sharpness of the disc cutter is calculated based on the following parameters: the radius of the small wedge-shaped cutting edge R1 before cutting, the radius of the small wedge-shaped cutting edge R2 after cutting, the cutting power W1, the stable cutting power W2, the cutting power W3, the time t for each cutting stage, and the cutting length L for each cutting stage. The calculation formula is as follows:

[0011]

[0012] Where f is the sharpness of the disc cutter, G is the fracture toughness of the material being cut, t1 is the time from the start of cutting to the end of the infeed stage, t2 is the time from the start of cutting to the end of the stable cutting stage, t3 is the time from the start of cutting to the end of the cutout stage, L1 is the cutting length of the infeed stage, L2 is the cutting length of the stable cutting stage, L3 is the cutting length of the cutout stage, and H is the Shore hardness of the material being cut.

[0013] Furthermore, the calculation method for the cutting-in work W1 is as follows:

[0014]

[0015] because

[0016] Therefore, the entry point

[0017] The method for calculating the stable cutting work W2 is as follows:

[0018] The method for calculating the cut-out work W3 is as follows:

[0019] Where F is the magnitude of the force on the disc cutter, Fx is the magnitude of the force on the disc cutter in the X-axis direction, and Fy is the magnitude of the force on the disc cutter in the Y-axis direction; V is the feed rate of the disc cutter, and Vx is the feed rate of the disc cutter in the X-axis direction.

[0020] Furthermore, images of the cutting process are acquired to obtain the time points of the entry stage, the stable cutting stage, and the exit stage. The start time point of the entry stage is the time when the disc cutter contacts the material being cut, and the end time point of the entry stage is the time when the depth of cut of the disc cutter into the material being cut reaches a preset value. The start time point of the stable cutting stage is the end time point of the entry stage, and the end time point of the stable cutting stage is the time when the disc cutter begins to cut out of the material being cut along the cutting direction. The start time point of the exit stage is the end time point of the stable cutting stage, and the end time point of the exit stage is the time when Fx and Fy decrease to zero.

[0021] Furthermore, the rotational speed n of the disc cutter is 800-3000 rpm, and the feed speed V of the disc cutter is 3000-10000 mm / min.

[0022] Furthermore, a disc cutter sharpness measuring device employing any one of the above-described disc cutter sharpness measurement methods includes a loading platform and a disc cutter motion mechanism, a disc cutter clamping mechanism, a material-to-be-cut motion mechanism, and a material-to-be-cut clamping mechanism mounted on the loading platform. The disc cutter motion mechanism can drive the disc cutter clamping mechanism to move along the Z-axis. A disc cutter is mounted on the disc cutter clamping mechanism and can drive the disc cutter to rotate. The material-to-be-cut motion mechanism can drive the material-to-be-cut clamping mechanism to move along the X-axis and Y-axis. The material-to-be-cut clamping mechanism is equipped with a force gauge. The material-to-be-cut clamping mechanism is used to clamp the material to be cut and to measure the cutting force when the material is cut by the disc cutter using the force gauge. An industrial camera is used to record images of the cutting process. A control terminal is signal-connected to the force gauge and the industrial camera and is used to determine the sharpness of the disc cutter based on the cutting force.

[0023] Furthermore, the disc cutter motion mechanism includes a lifting drive unit mounted on the loading platform and a lifting screw connected to the drive rod of the lifting drive unit. The disc cutter clamping mechanism is mounted on the lifting screw via a slider to move along the lifting screw in the Z-axis direction.

[0024] Furthermore, the disc cutter clamping mechanism includes a rotary motor connected to the slider and a cutter handle connected to the rotary shaft of the rotary motor. The disc cutter is detachably mounted on the cutter handle, and the rotary motor is adapted to drive the disc cutter to rotate at high speed.

[0025] Furthermore, the material cutting motion mechanism includes an X-axis drive rod mounted on the loading platform and a Y-axis drive rod movably mounted on the X-axis drive rod, and a material cutting clamping mechanism is mounted on the Y-axis drive rod.

[0026] Furthermore, the material clamping mechanism includes a fixed seat mounted on the Y-axis drive rod, a rotating seat rotatably mounted on the fixed seat, and a turntable mounted on the rotating seat, with the force gauge mounted on the turntable.

[0027] Furthermore, the fixed base is provided with a Y-axis rotation mechanism suitable for driving the rotating base to rotate around the Y-axis, and the rotating base is provided with a Z-axis rotation mechanism suitable for driving the turntable to rotate around the Z-axis; the force measuring instrument is provided with a clamp, which is suitable for clamping the material to be cut.

[0028] The technical solution of this invention has the following advantages:

[0029] 1. The disc cutter sharpness measurement method provided by this invention calculates the cutting attenuation coefficient of the disc cutter edge by recording the small wedge angle radius of the disc cutter before and after cutting the material. By establishing the change curves of the force magnitude and force time of the disc cutter moving on the X and Y axes to cut the material, the process of the disc cutter cutting the material is divided into three stages. Then, the sharpness of the disc cutter is calculated based on the work done by the disc cutter in the three stages, the small wedge angle radius before and after cutting, the cutting time, the cutting length, and the hardness of the material being cut. Compared with the traditional test of the disc cutter in the static cutting process, this dynamic cutting test method can more accurately obtain the sharpness of the disc cutter.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figure 5-7 The method for measuring the sharpness of a disc cutter, as shown, includes the following steps:

[0048] During the process of the disc cutter cutting the material, the disc cutter is driven to cut the material at a uniform speed of rotation speed n and feed speed V; the small wedge angle cutting edge radius R1 before cutting and the small wedge angle cutting edge radius R2 after cutting are recorded.

[0049] During the cutting process, the magnitude of the force F on the disc cutter is measured in real time; the Fx-t curve is established based on the relationship between the magnitude of the force Fx on the disc cutter in the X-axis direction and time t, and the Fy-t curve is established based on the relationship between the magnitude of the force Fy on the disc cutter in the Y-axis direction and time t.

[0050] Based on the variation curves of Fx-t and Fy-t, the disc cutter cutting process is divided into the entry stage, the stable cutting stage, and the exit stage, and the entry work W1, the stable cutting work W2, and the exit work W3 are calculated respectively.

[0051] The sharpness of the disc cutter is calculated based on the following parameters: the radius of the small wedge-shaped cutting edge R1 before cutting, the radius of the small wedge-shaped cutting edge R2 after cutting, the cutting power W1, the stable cutting power W2, the cutting power W3, the time t for each cutting stage, and the cutting length L for each cutting stage. The calculation formula is as follows:

[0052]

[0053] Where f is the sharpness of the disc cutter, G is the fracture toughness of the material being cut, t1 is the time from the start of cutting to the end of the cutting phase, t2 is the time from the start of cutting to the end of the stable cutting phase, t3 is the time from the start of cutting to the end of the cutting phase, L1 is the cutting length of the cutting phase, L2 is the cutting length of the stable cutting phase, L3 is the cutting length of the cutting phase, and H is the Shore hardness of the material being cut.

[0054] This method for measuring the sharpness of a disc cutter calculates the cutting attenuation coefficient by recording the small wedge angle radius of the disc cutter before and after cutting the material. It establishes curves showing the change in force and time as the disc cutter moves along the X and Y axes while cutting the material, dividing the cutting process into three stages. The sharpness is then calculated based on the work done by the disc cutter in each stage, the small wedge angle radius before and after cutting, the cutting time, the cutting length, and the hardness of the material. Compared to traditional static cutting tests, this dynamic cutting test method can more accurately determine the sharpness of the disc cutter.

[0055] In this embodiment, the cutting work W1 is calculated as follows:

[0058] Therefore, the entry point

[0059] The method for calculating the stable cutting work W2 is as follows:

[0060] The method for calculating the cut-out work W3 is as follows:

[0061] Where F is the magnitude of the force on the disc cutter, Fx is the magnitude of the force on the disc cutter in the X-axis direction, and Fy is the magnitude of the force on the disc cutter in the Y-axis direction; V is the feed rate of the disc cutter, and Vx is the feed rate of the disc cutter in the X-axis direction.

[0062] In this embodiment, as Figure 8 As shown, by acquiring images of the cutting process, the time points of the entry stage, the stable cutting stage, and the exit stage are obtained. The starting time point of the entry stage is the time point when the disc cutter contacts the material being cut (reference). Figure 8 (a) The end time of the cutting phase is the time when the depth of cut of the disc cutter into the material being cut reaches a preset value (refer to...). Figure 8 (b) The start time of the stable cutting stage is the end time of the cutting stage, and the end time of the stable cutting stage is the time when the disc cutter begins to cut out of the material along the cutting direction (see reference). Figure 8 c); the starting time of the cutting phase is the ending time of the stable cutting phase, and the ending time of the cutting phase is the time when Fx and Fy decrease to zero.
