Path contours  Cartesian coordinates
Define the workpiece blank for graphic workpiece
simulation
Call the tool in the spindle axis and with spindle speed
Retract the tool in the spindle axis at rapid traverse FMAX
Pre-position the tool
Move to working depth at feed rate F = 1000 mm/min
Approach the contour at point 1 on a straight line with
tangential connection
Move to point 2
Point 3: first straight line for corner 3
Program a chamfer with length 10 mm
Point 4: 2nd straight line for corner 3, 1st straight line for
corner 4
Program a chamfer with length 20 mm
Move to last contour point 1, second straight line for corner
4
Depart the contour on a straight line with tangential
connection
Retract the tool, end program
