cnc programming || Tool nose radius compensation G40,G41,G42

Tool nose radius compensation || G40,G41,G42 tool compensation


Function and purpose:-

The tool nose is generally rounded and so a hypothetical tool nose point is treated as the tool nose for programming .with such a programming, an error caused by the tool rounding arises during taper cutting or arc interpolation between the actually programmed shape and the cutting shape. Nose R or Tool radius compensation is a function for automatically calculating and offsetting this error by setting the nose radius or tool radius value.

Programming Format:-

G40 = Nose R/Tool radius compensation mode cancel

G41 = Nose R/Tool radius compensation left mode ON

G42 = Nose R/Tool radius compensation right mode On
