12.4.4 Interrupts During Tool Radius Compensation

MDI interrupt
Tool radius compensation is valid in any automatic operation mode-whether tape, memory or MDI
operation.
An interrupt based on MDI will give the result as in the figure below after block stop during tape or
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-calculated 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. ;
