Tool traverse path
ShopMill
The programmed positions are machined with the previously programmed tool (e.g.
center drill). Machining of the positions always starts at the reference point. In the case of
a grid, machining is performed first in the direction of the 1st axis and then meandering
back and forth. The frame and hole circle are machined counterclockwise.
G codes
For G code, for lines/frames/grids, a start is always made at the next corner of the frame
or grid or the end of the row. The frame and hole circle are machined counterclockwise.
