CANNED CYCLE FOR DRILLING

12.7.1

Canned Cycle for Drilling

Overview

Canned cycles for drilling make it easier for the programmer to create programs. With a canned cycle for
drilling, a frequently-used machining operation can be specified in a single block with a G code; without
canned cycles for drilling, normally more than one block is required. In addition, the use of canned cycles
for drilling can shorten the program to save memory.

Explanation

A canned cycle for drilling consists of a sequence of six operations.
Operation 1

Positioning a hole position

Operation 2

Rapid traverse up to point R level

Operation 3

Hole machining

Spindle control

In some canned cycles for drilling, a spindle command to rotate the spindle in reverse direction may be
output automatically.

The following canned cycles for drilling require spindle control:

<Machining center system>

<Lathe system>

Counter tapping cycle

G74

Face tapping cycle

G84

Fine boring cycle

G76

Side tapping cycle

G88

Tapping cycle

G84

Boring cycle

G86

Back boring cycle

For spindle control, the following normal miscellaneous functions are used:
See the description of the miscellaneous functions.

M03 CW spindle rotation

M04 CCW spindle rotation

M05 Spindle stop

M19 Spindle orientation (machining center system)

When the rotation direction of the spindle is to be switched from one direction to the other (for example,
when M04 is output during M03 operation), a parameter can specify whether to send M05 at the time
switching.

M code used for C-axis clamp/unclamp

When an M code specified in parameter No. 5110 for C-axis clamp is commanded, the CNC issues the M
code for C-axis clamp after the tool is positioned and before the tool is fed in rapid traverse to the point-R
level. The CNC also issues the M code (M code C-axis clamp +1) for C-axis unclamp after the tool
retracts to the point-R level. The tool dwells for the time specified in parameter No. 5111.

Tapping signal

During a tapping cycle, the tapping signal TAP <Fn001.5> is output. The tapping signal is output not
only during the tapping machining but also during the G code of the tapping cycle is valid.

Override

During tapping, cutting feedrate override is always set to 100%.

Feed hold

When the feed hold key is pressed during tapping, the movement is not stopped immediately but the
movement is stopped when the tool is returned to level R.

Dry run

The bit 5 (TDR) of parameter No. 1401 specifies whether dry run is valid during tapping.

Small-hole peck drilling cycle execution signal

In the small-hole peck drilling cycle mode, the small-hole peck drilling cycle execution signal PECK2
<Fn066.5> is output when positioning at point R on the drilling direction axis is started after positioning
at a specified hole position is performed with G83 specified. This signal is not output if another canned
cycle is specified or this mode is canceled by G80, a reset, or an emergency stop.

Overload torque detection signal

For the overload torque detection signal in the small-hole peck drilling cycle, a skip signal SKIP

<X004.7>, SKIP

<X013.7>, or SKIP

<X011.7> is used. The skip signal is valid (a retract operation is

(Note 1) When parameter M5T (No.

5105#3)=0, M05 is not output.

parameter No. 5112 and 5113.

Signal

Tapping signal TAP<Fn001.5>

[Classification] Output signal

[Function] Reports that the system is in tapping mode.

[Output cond.] The signal is set to “1” when:

The system is in tapping cycle mode.

(G74,G84 : for M series)

(G84,G88 : for T series)

The system is in tapping mode.

(G63 : for M series)

The signal is set to “0” when:
-

The system is in neither tapping cycle mode nor tapping mode.

A reset or emergency stop is specified.

Overload torque detection signal SKIP

<X004.7>, SKIP

<X013.7>, SKIP

<X011.7>

[Classification] Input signal

[Function] Refracts the tool on which an overload torque is imposed.

[Operation] When this signal is set to “1”, the control unit performs the following operation:

When an overload torque is imposed, the tool is retracted to point R then machining
is repeated after changing the spindle speed and cutting feedrate.

This signal is valid (a retract operation is performed) only when the tool on the
drilling axis is located between point R and point Z and the tool is moving forward
or performing a cutting operation.

NOTE

This signal is used also as a skip signal.

Small-hole peck drilling cycle execution signal PECK2<Fn066.5>

[Classification] Output signal

[Function] Posts whether the small-hole peck drilling cycle is being executed.

[Output cond.] This signal is set to “1” for the following period:

Period from the start time of positioning at point R on the drilling direction axis after
positioning at a hole position is performed with G83 specified in this cycle mode
until another canned cycle, which may be G80, or a G code of group 01 is specified
or until this mode is canceled by a reset or emergency stop.

This signal is not set to “1” in a state other than the above.
