Embodiment 1

[0044] figure 1 It is a flow chart of a tool error compensation method provided in Embodiment 1 of the present invention. The method is used for an edge milling machine and includes the following steps:

[0045] Step S11: Measure the tool of the edge milling machine to obtain the diameter of the tool.

[0046] In the embodiment of the present invention, after the worker uses the edge milling machine to grab the tool for processing, he can use the edge milling machine to measure the tool, so as to obtain parameters such as the diameter and length of the tool. Wherein, the edge milling machine can be connected with computer equipment, through which the staff can control the edge milling machine to grab the tool for measurement, and receive and store the measured parameters. The process of the above-mentioned edge milling machine grabbing the tool and measuring it can also be a fully automatic process, for example, an application program can be run in the computer equipment to c...

Embodiment 2

[0055] figure 2 It is a flow chart of calculating the compensation value of a tool error compensation method provided by Embodiment 2 of the present invention, including the following steps:

[0056] Step S21: Using the diameter of the tool and the width of the straight path, calculate the diameter deviation of the tool.

[0057] Step S22: Calculate the position deviation of the straight line path incision according to the first starting point coordinates, the first ending point coordinates, the second starting point coordinates and the second ending point coordinates.

[0058] Step S23: Calculate the compensation value by using the diameter deviation and the position deviation, and use the compensation value to perform error compensation on the tool.

[0059] In the embodiment of the present invention, the straight-line path includes processing in the test processing area with (X 1 ,Y 1 ) as the starting point, (X 2 ,Y 1 ) is the straight line path of the end point, whe...

Embodiment 3

[0065] image 3 It is a flow chart of a tool error compensation method provided by Embodiment 3 of the present invention. The method is used for edge milling machines and includes the following steps:

[0066] Step S31: Measure the tool of the edge milling machine to obtain the diameter of the tool.

[0067] This step is consistent with the above step S11, and will not be repeated here.

[0068] Step S32: After acquiring the diameter of the tool, judge whether the diameter of the tool is within the pre-stored acceptable tolerance range, and return the tool if the diameter of the tool is not within the pre-stored acceptable tolerance range.

[0069] In the embodiment of the present invention, after the computer device obtains the diameter of the tool, it can also judge whether the diameter measurement result of the tool is within the pre-stored tolerance range. When the tool diameter is not within the pre-stored tolerance range, the computer device can control the milling The...

Abstract

The invention provides a cutter error compensation method and device, computer equipment and a computer storage medium. The cutter error compensation method is used for compensating the error of a cutter of an edge milling machine, and the method comprises the steps: measuring a cutter of the edge milling machine, and obtaining the diameter of the cutter; processing a linear path in a test processing area by using a cutter, and obtaining a first starting point coordinate and a first ending point coordinate of the linear path; acquiring the width of a linear path, a second starting point coordinate and a second ending point coordinate in the test processing area by using a CCD sensor; and determining a cutter compensation value according to the diameter, the width of the linear path, the first starting point coordinate, the first ending point coordinate, the second starting point coordinate and the second ending point coordinate, and performing error compensation on the cutter by utilizing the compensation value. According to the cutter error compensation method, manual intervention on cutter error compensation can be reduced, the error probability is reduced, and the cutter error compensation precision is improved.

Description

technical field [0001] The invention relates to the field of edge milling machining, in particular to a tool error compensation method, device, computer equipment and computer storage medium. Background technique [0002] With the continuous development of the manufacturing industry, various manufacturing industries have higher and higher precision requirements for process processing. For example, the edge milling machine used for process processing PCB boards, in order to meet the high-precision molding of PCB boards, the precision of its processing Very demanding. [0003] At present, the main factor affecting the precision of the edge milling machine is the error caused by tool wear. Therefore, before using the edge milling machine for processing, it is necessary to perform error compensation for the wear of the tool. The existing tool error compensation is mainly manually compensated by the preset settings of the edge milling machine, so the error rate is very high, and...
