Concept glossary

Tool Nose Radius Compensation
A technique that compensates for the radius of the cutting tool nose when programming CNC lathe operations to ensure accurate part dimensions.
G41 Tool Nose Compensation LEFT
G-code that applies tool nose compensation to the LEFT of the programmed path.
G42 Tool Nose Compensation RIGHT
G-code that applies tool nose compensation to the RIGHT of the programmed path.
Linear interpolation (G01)
A CNC command that produces straight-line motion between two points at a controlled feed rate, listed in the unit objectives.
Circular interpolation
CNC commands (G02/G03) that produce circular motion, listed in the unit objectives.
G02
Circular interpolation command for clockwise motion in CNC turning.
G03
Circular interpolation command for counter-clockwise motion in CNC turning.
I and K parameters
Parameters used in G02 and G03 codes to define the center point of circular motion relative to the start point.
