FANUC LTD.
Explanation
Explanation is same as the conventional NURBS interpolation.
Restrictions
Tool center point control for 5-axis machining
NURBS interpolation for 5-axis machining can be used together with Tool center
point control for 5-axis machining (type I: G43.4), but cannot be used together
with Tool center point control for 5-axis machining (type II: G43.5) and Tool
posture control of Tool center point control for 5-axis machining.
Tool radius compensation for 5-axis machining
Tool radius compensation for 5-axis machining cannot be simultaneously
executed. NURBS interpolation for 5-axis machining can only be specified after
Tool radius compensation for 5-axis machining has been canceled.
Other restrictions except for the number of controlled axes are same as the
conventional NURBS interpolation.
Parameters
Parameters are same as the conventional NURBS interpolation.
Alarms and messages
NURBS interpolation for 5-axis machining can be used together with Tool center
point control for 5-axis machining (type I: G43.4). However PS5421 alarm occurs
if NURBS interpolation for 5-axis machining is used with Tool center point
control for 5-axis machinig (type II: G43.5) or Tool posture control of Tool center
point control for 5-axis machining.
Other alarms are same as the conventional NURBS interpolation.
