R: Apprch angle (default: 0)
R = 0: Contour element is approached directly; infeed to
starting point above the milling plane—then vertical plunge
R > 0: Tool moves on approaching/departing arc that
connects tangentially to the contour element
R < 0 for inside corners: Tool moves on approaching/
departing arc that connects tangentially to the contour
element
R < 0 for outside corners: Length of linear approaching/
departing element; contour element is approached/departed
tangentially
RB: Return plane
SCI: Safety clearance in the working plane
SCK: Safety clearance in infeed direction
