3.11 Face milling – CYCLE71
Programming example
Face milling
Parameters for cycle call:
• Retraction plane:
• Reference plane:
• Safety distance:
• Milling depth:
• Max. infeed depth
• No final machining allowance
• Starting point of the rectangle
• Rectangle dimensions
• Angle of rotation in the plane
• Max. infeed width
• Retraction travel at the end of the
milling path:
• Feedrate for surface machining
• Type of machining: roughing parallel to the X axis
• Overrun on last cut as determined
by the cutting edge geometry
