What is the workpiece coordinate system in five-axis linkage machining?

Including: cutter axis vector, 3-axis half-open, multi-axis milling

1. Setting G52 in the local coordinate system with an example format: G52 X_Y_Z_; in the formula: X, Y, Z: the coordinate value of the origin of the local coordinate system of the five-axis machine tool in the current workpiece coordinate system. G52 instruction can form sub-coordinate system in all workpiece coordinate systems (G92, G54 ~ G59), that is, local coordinate system. In the program segment containing G52 instruction, the instruction value of absolute programming mode is the coordinate value in the local coordinate system. After setting the local coordinate system, the workpiece coordinate system and the machine tool coordinate system remain unchanged.

2. Programming examples: from A B C route, five-axis machine tool starting point at (20, 20, 0) can be programmed as follows: N02 G92 X20 Y20 Z0; set G92 as the current working coordinate system N04 G90 G00 X10 Y10; fast positioning to G92 working coordinate system A point N06 G54; set G54 as the current coordinate system N08 G90 G00 X10 Y10; fast positioning to G54 work B-point N10 G52 X20 Y20 in coordinate system; Local coordinate system G52 N12 G90 G00 X10 Y10 in current working coordinate system G54; C-point positioning in G52 1.
