You want to machine the outside contour of a pentagon.
Make sure that you enter the correct workpiece dimensions!
Approach starting point in rapid traverse: X70, Y50, radius compensation off.
Pole: X=50, Y=50
1. polar line: L=20, α= −72 absolute, radius compensation right
2. to 5th polar line: L=20, α= −72 degrees incremental,
radius compensation right
