CANNED GRINDING CYCLE

(FOR GRINDING MACHINE)

Explanations

When the multistage skip option is used, a gauge number can be specified. The method of

gauge number selection is the same as the method of multistage skip function. When the

multistage skip option is not used, the conventional skip signal is valid.

The same specifications as G73 is applied except for gauge number specification.

• Operation performed when the skip signal is input

When the cycle of G74 is performed, a skip signal can be input to terminate the cycle. When

a skip signal is input, the current operation sequence is interrupted or completed, then the

cycle is terminated.

The following shows how the system operates when the skip signal is input during each

operation sequence.

• When the skip signal is input during operation sequence (1) or (3) (dwell),

dwell is stopped immediately and the tool returns to the α coordinate at

which the cycle started.

• When the skip signal is input during operation sequence (2) or (4) (cutting

feed specified by A or B, and grinding movement), the tool returns to the α

coordinate at which the cycle started after the movement specified by W is

completed.

Page 4634.5 CANNED GRINDING CYCLE (FOR GRINDING MACHINE) Canned grinding cycles make it easier for the programmer to create programs that include grinding. With a canned grinding cycle, repetitive operation peculiar to grinding can be specified in a single block with a G function. Without canned grinding cy

Page 464WARNING The G codes of the canned cycle (G71, G72, G73, and G74) (in case of G code system C, G72, G73, G74, and G75) belong to the group 01 G codes. The canned grinding cycle dose not have the cancel G code such as G80 for the canned cycle for drilling. When a group 00 G code except for G04 is spec
