1、The cutting point can be set on the machined part, but note that thecutting point must be the reference position or the part that has been finished.
Sometimes the cutting point is destroyed by cnc machning after first process, which will lead to the second process And the subsequent cutting point cannot be found.However, during the first process of tool setting, pay attention to the establishment of a relative cutting location where there is a relatively fixed size relation with the positioning reference.
This position relative to the tool setting is usually set on the machine table or fixture
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, and 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.
