14 The Tool Compensation

The path of tool will be as follows when instructions G22, G23, G52, G54-G59, G92

G53

G28, G29, G30

are inserted between two interpolations.

When command G22, G23, G52, G54-G59 or G92 is programmed in offset mode between two interpolation blocks, the compensation vector will be deleted at the end point of the previous interpolation, the command will be executed and the vector will be restored at the end point of the next interpolation. If the previous or next interpolation is a circular one, the control will return error message 3041 AFTER G2, G3 ILLEG. BLOCK.

For example:

...G91 G17 G41...

N110 G1 X80 Y–50

N120 G92 X0 Y0

N130 X80 Y50

...

If command G53 is programmed in offset mode between two interpolations, the compensation vector will be deleted at the end point of the previous block, the positioning will be executed in G53, and the vector will be restored at the end point of the next interpolation (other than G53). If the previous or next interpolation is a circular one, the control will return error message 3041 AFTER G2, G3 ILLEG. BLOCK.

For example:

...G91 G17 G41...

N110 G1 X80 Y–50

N120 G53 Y80

N130 G53 Y0

N140 X80 Y50
