(G97 without LIMS for ISO mode
m
G963 Reserved m
Group 16: Feedrate override on inside and outside curvature
Name No. Meaning X m/n SAG MM
CFC 1. Constant feed at contour
m Def.
CFTCP 2. Constant feed in tool center point
(center-point path)
m
CFIN 3. Constant feed at internal radius, acceleration at external radius
m
Group 17: Approach and retraction response, tool offset
Name No. Meaning X m/n SAG MM
NORM 1. Normal position at start and end points m Def.
KONT 2. Travel around contour at start and end points m
KONTT 3. Insert polynominal with constant tangent (approach/retract) m
KONTC 4. Insert polynominal with constant curvature (approach/retract) m
Group 18: Corner behavior, tool offset
Name No. Meaning X m/n SAG MM

BNAT 1. Begin natural: natural transition to first spline block m Def.
BTAN 2. Begin tangential: tangential transition to first spline block m
BAUTO 3. Begin not a node: (no node) Start is determined by the position of the
1st point
