Movement in compensation mode

When after the tool radius compensation is
programmed by G41, G42, the tool moves along

the offset path until the instruction G40 is

g i v e n .

As talc

of the path is automatically

made by the control, designate only the
shape of the

in the program. The

tool path is controlled as follows depending
on the angle between blocks.

A .

Inside corner ( 180° or less) :
Intersection computing type

Fig. 2.35

B .

Outside corner (over 180°) :
Circular path type (in the case of M96)

Fig. 2.36

In this case, movement of circular path is
included in the former block.

M96 . . .

Tool radius compensation circular
path ON

M97 . . .

Tool radius compensation circular

path OFF (execution of intersection
computation)

Normally, M96 is used for this operation,
h o w e v e r , when there is a possibility of an

in cutting special shapes with the

M96, M97 should be used.

c .

Movement in GOO mode

The instruction GOO positions tools independ-
ently along each axis toward the final offset
position.

Care should be taken on the cutter

path.

M96 mode)

Code M97 can be used to machine the outside cor-
ner by the intersection computation, depending on
the work. For details, refer to 2.8.6, “CIRCULAR
