The tool setting point can be set on the part to be processed, but note that the tool setting point must be the reference position or the part that has been finished. Sometimes the tool setting point is destroyed by cnc processing after the first process, which will cause the second It is impossible to find the tool setting point for the process and the subsequent process. Therefore, when setting the tool in the first process, pay attention to setting up a relative tool setting position where there is a relatively fixed size relationship with the positioning datum, so that it can be based on the relative position relationship between them. Retrieve the original knife point. This relative tool setting position is usually set on the machine tool table or fixture.
The selection principles are as follows:
Alignment is easy. Easy to program. The tool setting error is small. It is convenient and available to check during processing.
