Procedure
1. The ShopMill program to be edited has been created and you are in the
editor.
2. Press the menu forward key and the "Straight Circle" softkey.
3. Press the "Helix" softkey.
Parameter Description Unit
Direction of rotation The tool travels in the programmed direction from the circle starting point to its end
point. You can program this direction as clockwise or counterclockwise.
Clockwise direction of rotation
Counterclockwise direction of rotation
I Center point of the helix in the X direction (abs or inc) mm
J Center point of the helix in the Y direction (abs or inc) mm
P Helix pitch The pitch is programmed in mm per revolution. mm/rev
Z Target position of the helical end point (abs or inc) mm
F Machining feedrate mm/rev
mm/min
mm/tooth
10.7.12 Polar coordinates
If a workpiece has been dimensioned from a central point (pole) with radius and angles, you
will find it helpful to program these as polar coordinates.
You can program straight lines and circles as polar coordinates.
Defining a pole
You must define the pole before you can program a straight line or circle in polar coordinates.
This pole acts as the reference point of the polar coordinate system.
The angle for the first line or circle then needs to be programmed in absolute coordinates. You
can program the angles for any additional straight lines and circles as either absolute or
incremental coordinates.
