Description

Technical Field

[0001] The invention relates to the technical field of aeroengines, and in particular to a method for automatically calling, activating and calibrating an L-shaped probe added to a numerical control device. Background Art

[0002] In the construction of automated production lines, it is necessary to add probes to CNC equipment, especially L-type probes, which are of great significance for the automated production of disk and ring parts. Since the M command to activate the probe needs to be set by the manufacturer, if you want to add a probe, you need to find the equipment manufacturer to add the M command, which increases the cost and time of the transformation. This method describes the method of adding probes on site in a non-manufacturer way, making compound M commands to activate the probe, and calibrating the L-type probe. Summary of the invention

[0003] The purpose of the present invention is to add a probe to a numerical control device and complete the calling, calibration and activation of the probe, avoid the intervention of the manufacturer, save time and equipment modification costs, serve the needs of automated production line construction, and provide a method for adding an L-shaped probe to a numerical control device for automatic calling, activation and calibration.

[0004] The present invention provides a method for automatically calling, activating and calibrating an L-shaped probe in a numerical control device, comprising the following steps:

[0005] 1. Check the manufacturer's probe activation method, which is divided into the following two types

[0006] 1.1. Use sister tool method to activate all probes by unified M command

[0007] 1.2. Use a dedicated M command to activate (4 M commands are required, but the device only has one M command)

[0008] 2. Programming

[0009] 2.1. For the situation in 1.1, compile the arbitrary calling program of the sister knife

[0010] 2.1.1. Read out the tool internal number X corresponding to all probes through $TC_TP2[X] = probe name, where X is an integer

[0011] 2.1.2、How to call the sister knife:

[0012] By $TC_TP8[X]B_AND'B100'==4

[0013] $TC_TP8[X]=$TC_TP8[X]B_XOR 4

[0014] $TC_TP8[X]=$TC_TP8[X]B_OR 4

[0015] The instruction opens the available authorization for the probes that need to be used and closes the available authorization for the probes that do not need to be used, so as to ensure that the probes that should be used can be called out and activated.

[0016] 2.2 Prepare compound M instructions for situation 1.2

[0017] 2.2.1. Record the original probe start M command

[0018] 2.2.2. Principles for making compound instructions: Look for M instructions that have no effect on measurement in the M instruction table, such as using the bed flushing instruction together with the machine tool's built-in probe activation instruction to make additional probe activation instructions.

[0019] For example, the probe is turned on by M74 and turned off by M73; the bed flushing is turned on by M46 and turned off by M45.

[0020] The method for making a compound instruction is:

[0021] %_N_UNAC_DEF

[0022] DEFINE M741 AS M74

[0023] DEFINE M742 AS M74 M46

[0024] DEFINE M73 AS M73 M45

[0025] M741 is the first probe start command, M742 is the second probe start command, and M73 is the probe close command.

[0026] 3. Additional probe pairing method

[0027] 3.1. Adjust the probe opening mode of the probe receiver RMI_Q to the dedicated end opening

[0028] 3.2. Adjust the additional probe to pairing mode: the indicator light is blue and red

[0029] 3.3. Supply power to RMI_Q and ensure that the input signal of the additional probe start terminal remains at a high level.

[0030] 3.4. The probe indicator light turns blue, and the probe pairing is complete.

[0031] 3.5. After pairing is completed, adjust the probe opening mode of the probe receiver RMI_Q to common opening

[0032] 3.6. Connect the second probe start line, for example: connect the second probe start line to the bed flushing start relay

[0033] 4. Calibration of L-type probe

[0034] 4.1. Installation of probe calibration standard parts

[0035] 4.1.0. Straighten the probe calibration standard 1 so that it is parallel to the X-axis or Y-axis of the machine tool and make the spindle perpendicular to the surface of the probe calibration standard 1.

[0036] 4.1.1. Use only the straight probe to measure the value of the probe calibration standard 1 in the machine tool coordinate system, recorded as W1

[0037] 4.1.2. Based on the distance between the probe calibration standard parts 1 and 2, infer the value of the probe calibration standard part 2 in the machine tool coordinate system, which is recorded as W2

[0038] 4.2. Calibrate L-type probe using probe calibration standard

[0039] 4.2.1. Use the value W1 to calibrate the tool length position of the L-type probe. Figure 4 :Calibration movement direction is left, probe tool type is set to 712 or 714

[0040] 4.2.2. Use the value W2 to calibrate the blade length position of the L-type probe puller. Figure 5 :Calibration movement direction is right, probe tool type is set to 713

[0041] 4.2.3. Use $TC_DP10 to set the angle. The angle is the main axis angle when the measuring rod is parallel to the Y axis.

[0042] 4.2.4. Use CYCLE976 to calibrate the 713 probe, where the parameter D_DMODE must be set to "0"

[0043] 5. Precautions for using the probe

[0044] 5.1. Each cutting edge of the probe must be calibrated before use. The cutting edge data cannot be reviewed by copying the tool excitation length, and the CNC system will not recognize it.

[0045] 5.2. The starting position of the probe calibration should be in a reasonable position to prevent the system from reporting an error - check the measurement direction.

[0046] 5.3. As an L-type probe, due to the existence of center of gravity offset, it is necessary to use an enhanced probe and set the filter time. The filter time should be selected according to the different spindle positioning speeds. The filter time is short when the positioning speed is fast and long when the positioning speed is slow.

[0047] 5.4. In order to improve the measurement accuracy, the dimension L2 needs to be larger than the dimension

[0048] 5.5. For five-axis machining equipment with swing heads, if the measurement results after using CYCLE800 are significantly different from the theoretical results, it is necessary to calibrate the probe while the CYCLE800 workpiece coordinate system is rotated, such as Figure 6 .

[0049] Compared with the prior art, the present invention has the following advantages:

[0050] The method for automatically calling, activating and calibrating an L-shaped probe for adding to numerical control equipment of the present invention solves the problem that the addition of a probe to imported equipment requires the intervention of the manufacturer, thereby saving more than 100,000 yuan in equipment modification costs, and the cost savings are directly proportional to the time saved.
