1.5 Coordinate systems and workpiece machining
The relationship between travel commands of the programmed axis movements from the
workpiece coordinates and the resulting machine movement is displayed.
How you can determine the distance traveled taking into account all shifts and corrections is
shown by reference to the path calculation.
Relationship between the travel commands from workpiece coordinates and the resulting machine
movements
Axis movement programmed in the workpiece coordinate system
Path calculation
The path calculation determines the distance to be traversed in a block, taking into account
all offsets and compensations.
In general:
Distance = setpoint - actual value + zero offset (ZO) + tool offset (TO)
