G70 command
When G71～G73 is executed, the system temporarily cancels C tool compensation. When G70
is specified again, the system automatically recovers the compensation mode. Because the system
executes G71～G73, it does not execute the radius compensation, there must be the finishing
allowance in programming to avoid the overcut in roughing.
In G70, the compensation mode is not cancelled after the cycle end, the system continuously
executes the compensation in the fixed point, which causes the undercut of the finishing cycle in the
last block, so, the last should exceeds one tool radius value of the workpiece in programming.

Inside chamfer machining less than tool nose radius
At the moment, the tool inside offset causes an excessive cutting. The tool stops and the system
alarms ( P/S41) when starting the previous block or chamfer moving. But the tool stops the end point
of previous block when Single is ON.
