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
F300
Approach the contour at point 1 on a circular arc with
tangential connection
Point 2: first straight line for corner 2
Insert radius with R = 10 mm, feed rate: 150 mm/min
Move to point 3: Starting point of the arc with CR
Move to point 4: End point of the arc with CR, radius 30 mm
Move to point 5
Move to point 6
Move to point 7: End point of the arc, radius with tangential
connection to point 6, TNC automatically calculates the radius
Move to last contour point 1
Depart the contour on a circular arc with tangential connection
Retract in the tool axis, end program
