12.3.4 Interrupts during tool radius compensation

MDI interrupt
Tool radius compensation is valid in any automatic operation mode-whether memory or MDI
operation.
An interrupt based on MDI will give the result as in the figure below after block stop during memory
operation.
(1) Interrupt without movement (tool path does not change)
N1 G41D1;
N2 X20. Y50. ;
N3 G3 X40. Y-40. R70. ; S1000 M3;
(2) Interrupt with movement
The offset vectors are automatically re-ca
lculated at the movement block after interrupt.
With linear interrupt
N1 G41D1;
N2 X20. Y50. ;
N3 G3 X40.Y-40. R70. ; X50. Y-30. ;
With circular interrupt
N1 G41 D1 ;
N2 X20. Y50. ;
N3 G3 X40. Y-40. R70.; G2 X40. Y-40. R70. ;
