Creating a ShopMill program
7.3 Basic information
End of program
End of program signals to the machine that the machining of the workpiece has ended. In
addition, you can specify the number of workpieces that you would like to machine.

Basic information
7.3.1
Machining planes
A plane is defined by means of two coordinate axes. The third coordinate axis (tool axis) is
perpendicular to this plane and determines the infeed direction of the tool (e.g. for 2½-D
machining).
When programming, it is necessary to specify the working plane so that the control system
can calculate the tool offset values correctly. The plane is also relevant to certain types of
circular programming and polar coordinates.
Working planes
Working planes are defined as follows:
Plane
X/Y
Z/X
Y/Z
7.3.2
Polar coordinates
The rectangular coordinate system is suitable in cases where dimensions in the production
drawing are orthogonal. For workpieces dimensioned with arcs or angles, it is better to
define positions using polar coordinates. This is possible if you are programming a straight
line or a circle.
Polar coordinates have their zero point at the "pole".
