Approach and departure functions are used to gently move the tool to or from a contour, without leaving any machining marks on the workpiece.
The APPR folder of the Insert NC function window contains the following functions:
Symbol | Function | Further information |
---|---|---|
APPR LT or APPR PLT Use Cartesian or polar coordinates to approach a contour on a straight line with a tangential connection | ||
APPR LN or APPR PLN Use Cartesian or polar coordinates to approach a contour on a straight line perpendicular to the first contour point | ||
APPR CT or APPR PCT Use Cartesian or polar coordinates to approach a contour on a circular path with a tangential connection | ||
APPR LCT or APPR PLCT Use Cartesian or polar coordinates to approach a contour on a circular path with a tangential connection and a straight line |
The DEP folder of the Insert NC function window contains the following functions:
Symbol | Function | Further information |
---|---|---|
DEP LT Depart contour on a straight line with a tangential connection | ||
DEP LN Depart contour on a straight line perpendicular to the last contour point | ||
DEP CT Depart contour on a circular path with a tangential connection | ||
DEP LCT or DEP PLCT Use Cartesian or polar coordinates to depart a contour on a circular path with a tangential connection and a straight line |
You can switch between entry of Cartesian and polar coordinates in the form or by pressing the P key.
