2.9.7 EXACT STOP

G61, G64) (Cent’d)

Notes :

. In the Error Detect On mode, the program pro-

ceeds to the next block only after the number
of servo delay pulses is found to have decreas-
ed below a permissible limit following the com-
plete distribution of circular interpolation
command pulses.

In the G09 and G61. off modes, the program pro-
ceeds to the next block immediately after the
complete distribution of the pulses of ordinary
linear and circular interpolations, and there-
fore, because of the servo delay, tool pathes
are rounded at the corner. This mode is called

Detect

‘ode”

. For rapid traverse, the Error Detect On and

Off modes are controlled only by GOO and

G 0 6 ,

and not by the above G codes.

2.9.8 TOOL OFFSET VALUE DESIGNATION (G1O)

With a G1O command, correction of tool offset
values and work coordinate system can be made

as follows.

(1) Designation of tool offset value ( G1O)

Normally, tool offset values are written in by
MDI .

On the other hand, with a program G1O

; , (where P = tool offset number

and R = tool offset value) , any programmed
offset values can be replaced by a designated
value.

When G1O is commanded in the G90 mode, R is

stored as it is.

When G1O is commanded in the G91

added in the previous tool offset value.

2.9.9 CIRCLE CUTTING

This is a canned cycle which includes a complete
series of movements for machining a circle in a
single block.

It includes the following functions.
