Horizontal machining center in the processing parts, as a result of the parts processing part of the demand, usually requires the table to rotate arbitrary viewpoint.
When the origin of workpiece coordinate system coincides with the rotation center of the workbench, the rotation of the workbench will not affect the machining. But because the choice of the origin of the workpiece coordinate system is based on the characteristics of the part structure, programming requirements and determine, usually processed parts can not coincide with the center of the rotation of the workbench, the workpiece coordinate system origin with the rotation of the workbench, in the machine coordinate system changes.
Therefore, reset the origin of the workpiece coordinate system. Each horizontal machining center z axis spindle end face and B axis inversion center has a fixed value, because the horizontal plus B axis rotation time, with the macro program conversion coordinate system time needs to use this value, the following is a simple and feasible method for our company.
A after the workpiece coordinate system origin set, according to the compensation value, artificial calculation of the other workpiece coordinate system origin and input into the workpiece coordinate system, and the corresponding easy to make mistakes, and only accounting worktable rotate 90 degrees, 180 degrees, 270 degrees of orientation of the workpiece coordinate system origin, not accounting point on the arbitrary rotation coordinate system origin.
The program according to the initial workpiece coordinate system origin set value, realize the workbench rotating arbitrary viewpoint of workpiece coordinate system origin automatic compensation, and set a new workpiece coordinate system origin, automatically input into the workpiece coordinate system, the corresponding reduced the workpiece coordinate setting time and error probability, improve the production efficiency and accuracy.
