Method for establishing coordinate system in three-coordinate measuring electrode

Abstract

The invention relates to a method for establishing a coordinate system in a three-coordinate measurement electrode. Compared with a mainstream electrode measurement method in the industry, the method is more convenient , and the whole measurement operation is more efficient. According to the method, the single points are arranged on the electrode reference table, path optimization is achieved by means of independence of the single points, then all the single points participate in calculation, a balanced matrix is maintained together, and finally an accurate coordinate system is established. Although the method is displayed on the electrode, the method can be completely popularized to measurement of other parts, and development of the measurement cause is facilitated.

Description

technical field [0001] The invention relates to the field of three-coordinate precision detection, and relates to a method for establishing a coordinate system in the process of precise detection of electrodes used in spark machines in the machining industry on three coordinates. Background technique [0002] In the process of electrode measurement, the establishment of a coordinate system is the premise of measurement, while the traditional measurement methods mostly use digital models for offline programming, collect one surface element and four line elements on the digital model, and use the 321 method to establish coordinates after constructing the center line System, this method is the most primitive method of operation, almost no advantages, the disadvantages are very prominent, for example: [0003] 1. When operating manually, there are many operating elements that will cause inefficiency; [0004] 2. When manually picking surface elements, the probe will move around...

[0002] In the process of electrode measurement, the establishment of a coordinate system is the premise of measurement, while the traditional measurement methods mostly use digital models for offline programming, collect one surface element and four line elements on the digital model, and use the 321 method to establish coordinates after constructing the center line System, this method is the most primitive method of operation, almost no advantages, the disadvantages are very prominent, for example:

[0003] 1. When operating manually, there are many operating elements that will cause inefficiency;

[0004] 2. When manually picking surface elements, the probe will move around the electrode for one circle. When picking four line elements, the probe will move around the electrode for another circle. It takes a lot of time to complete the two-turn movement trajectory, and the electrode size is small. , the time-consuming feeling when encountering larger electrodes will be very obvious;

[0005] 3. The code statement generated from the construction of the software operation to the establishment of the coordinate system is very lengthy and the operation is relatively cumbersome

[0009] Compared with the former, the introduction of Erowa fixtures has a greater innovation, which saves time and effort, but in the early stage, enterprises need to invest tens of thousands to hundreds of thousands to introduce Erowa fixtures according to their own scale, and the later maintenance costs are calculated separately, which causes There are many companies that use Erowa fixtures, and some are useless

It is a pity that he still has not been able to change the disadvantages of the software operation, from the construction to the establishment of the coordinate system, the generated code statements are very lengthy and the operation is relatively cumbersome.
