7.10 Automatic corner override ; G62

Function and purpose
With tool radius compensation, this function reduces the load during inside cutting of automatic
corner R, or during inside corner cutting, by automatically applying override to the feed rate.
Automatic corner override is valid until the tool radius compensation cancel (G40), exact stop
check mode (G61), high-accuracy control mode (G61.1), tapping mode (G63), or cutting mode
(G64) command is issued.

Machining inside corners
When cutting an inside corner as in Fig. 1, the machining allowance amount increases and a
greater load is applied to the tool. To remedy this, override is applied automatically within the
corner set range, the feedrate is reduced, the increase in the load is reduced and cutting is
performed effectively.
However, this function is valid only when finished shapes are programmed.
