3.MANUAL OPERATION OPERATION B-63944EN/02
- 884 -
Explanation
- Manual rigid tapping
Manual rigid tapping is enabled by parameter HRG (No. 5203#0) to 1.
- Cancellation of rigid mode
To cancel rigid mode, specify G80 as same the normal rigid tapping.
When the reset key is pressed, rigid mode is canceled, but the canned
cycle is not canceled.
When the rigid mode switch is to be set to off for rigid mode
cancellation (when parameter CRG (No. 5200#2) is set to 0), the G80
command ends after the rigid mode switch is set to off.
- Spindle rotation direction
The rotation direction of the spindle is determined by a specified
tapping cycle G code and the setting of parameter HRM (No. 5203#1).
For example, when the HRM parameter is set to 0 in G84 mode, the
spindle makes forward rotations as the tapping axis moves in the
minus direction. (When the tapping axis moves in the plus direction,
the spindle makes reverse rotations.)
- Arbitrary tapping axis
With the M series, an arbitrary tapping axis can be selected by setting
bit 0 (FXY) of parameter No. 5101 to 1. With the T series, an
arbitrary tapping axis can be selected not by using bit 0 (FXY) of
parameter No. 5101 (but by using bit 0 (FXY) of parameter No. 5101
when the FS15 format is specified). In this case, specify a G code
for plane selection and the address of the tapping axis when setting the
rigid tapping mode in the MDI mode.
- G84 command/same block specifying both M29 and G84
As the MDI program command for setting the rigid mode, G84 can be
specified as a rigid tapping G code (by setting bit 0 (G84) of
parameter No. 5200 to 1), or M29 and G84 can be specified in the
same block.
Example 1: G91 G84 Z0 F1000 S100 ;
Example 2: G91 G84 Z0 F1000 M29 S100 ;
- Specification of manual handle feed faster than the rapid traverse rate
Set parameter (No.7117) to 0 so that when manual handle feed is
specified which is faster than the rapid traverse rate, the handle pulses
beyond the rapid traverse rate are ignored.
- Series 15 format command
By setting bit 1 (FCV) of parameter No. 0001 to 1, the Series15
format can be used for specification.
Example 1: G91 G84.2(G84.3) Z0 F1000 S100; (M series)
Example 2: G84.2 W0 F1000 S100; (T series : G code systems B, C)
Example 3: G91 G84.2 Z0 F1000 S100; (T series : G code system A)
