Description
The control requires the following information in order to calculate the tool paths:
• Tool no. T/edge no. D
• Direction of machining G41, G42
• Working plane G17 to G19
Tool no. T/edge no. D
Where appropriate, a tool offset number D is also required. The distance between the tool
path and the workpiece contour is calculated from the cutter and tool edge radii and the tool
point direction parameters.

G41
G41
G41
With flat D number structure it is only necessary to program the D number.
