How to determine the tool setting point is more reasonable?

1. The tool setting point can be set on the processed parts, 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 There is no way to find the tool setting point in the next process and the following, so 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 reference, so that you can according to the relative position relationship between them Retrieve the original tool setting point. This relative tool setting position is usually set on the machine table or fixture. The selection principles are as follows:

1) Easy to find.
2) Easy programming.
3) The tool setting error is small.
4) The inspection is convenient and checkable during processing.

2. The origin position of the workpiece coordinate system is set by the operator. It is determined by tool setting after the workpiece is clamped. It reflects the distance and position relationship between the workpiece and the machine zero. Once the workpiece coordinate system is fixed, it is generally not changed. The workpiece coordinate system and the programming coordinate system must be unified, that is, during processing, the workpiece coordinate system and the programming coordinate system are the same.
