Define blank form for graphic workpiece simulation
Define tool in the program
Call tool in the spindle axis and with the spindle speed S
Retract 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 chamfer with length 10 mm
Point 4: 2nd straight line for corner 3, 1st straight line for corner 4
Program 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 in the tool axis, end program
