6 Programming: Programming Contours
6.5 Path Contours — Polar Coordinates
Example: Linear movement with polar coordinates
Define the workpiece blank
Define the tool
tool call
Define the datum for polar coordinates
Retract the tool
Pre-position the tool
Move to working depth
Approach the contour at point 1 on a circular arc with
tangential connection
Move to point 2
Move to point 3
Move to point 4
Move to point 5
Move to point 6
Move to point 1
Depart the contour on a circular arc with tangential connection
Retract in the tool axis, end program
