12.7.2

Canned Cycle Overlap for Drilling

Overview

With this function, during the canned cycle mode for drilling, the command can overlap with the next
block for the settime of the time constant of the acceleration/deceleration after interpolation.
This speeds up the operation of the canned cycle for drilling and shortens the cycle time.

Explanation

This function is valid when bit 0 (HDCx) of parameter No.1680 is set to 1.

Operations in which overlap is valid

Fig. 12.7.2 (a) Operations in which overlap is shows the operations in which overlap is valid in the
operation sequence of canned cycle for drilling.
When bits 0 to 5 of parameter No.1681 are set to 1, overlap is invalid in each operation.

Overlap time

Set the overlap time of this function to the parameters No.1686 and No.1687.
Parameters No.1686 and No.1687 are used as the time constant of the acceleration/deceleration after
interpolation common to both cutting feed and rapid traverse in canned cycle for drilling in which this
function is valid.
The command can overlap with the next block for the overlap time set within the time constant of the
acceleration/deceleration after interpolation. (Fig.12.7.2 (b))

Fig.12.7.2 (b) Overlap time

Parameters No.11248 and No.11249 are valid for axes whose parameters No.1686 and No.1687 are both
set to 0. (Table 12.7.2 (d))
Parameters No.11248 and No.11249 are the overlap time of Smart overlap. For Smart overlap, refer to
“Smart Overlap” in this manual.

This function has the following features, so usually the overlap amount can be increased compared to
Smart overlap.

- Since it is limited to operation within a cycle, interference due to overlap is less likely to be a

problem.

- Overlap can be invalidated for each cycle operation.

To reduce the cycle time, it is recommended that the overlap time of this function is set to the parameters
No.1686 and No.1687 separately from Smart overlap.

Normally, the overlap time constant 2 is not used. Set the parameters No.1687 and No.11249 to 0.

Acceleration/deceleration after interpolation during canned cycle for drilling

The following parameters are used as the time constant of the acceleration/deceleration after interpolation
in canned cycle for drilling in which this function is valid.
The relationship between the parameters and the time constant of the acceleration/deceleration is shown
in Table 12.7.2 (e)and Fig. 12.7.2 (c).

Tool path error at corner by overlap

When overlap is done where the movement direction changes, the overlapped path passes inward
compared to the programmed path. (Fig. 12.7.2 (d))

Fig. 12.7.2 (d) Tool path error at corner by overlap

When the overlap operations are continuous, overlap is performed not only between two blocks, but also
over two or more blocks. (Fig. 12.7.2 (e))

NOTE

It is necessary to care that tool does not interfere with workpiece by tool path
error at corner.

When bit 0 (DPS) of parameter No.1681 is set to 1, overlap is invalid at corner. If
it is required to avoid tool path error at corner, please set DPS to 1.

Tool path error at bottom of a hole by overlap

When dwell is not commanded at the bottom of a hole, overlap is done at the bottom of the hole.
In this case, the tool does not reach the programmed hole bottom because the direction of movement is
reversed before the programmed hole bottom. (Fig. 12.7.2 (f))

Fig. 12.7.2 (f) Tool path error at bottom of a hole by overlap

NOTE

When bit 5 (DZL) of parameter No.1681 is set to 1, overlap is invalid at bottom of
a hole. If accuracy at bottom of a hole is required, please set DZL to 1.

- Relationships with other functions

The relationships with other functions are as follows.

- Rapid traverse block overlap

This function can be used with rapid traverse block overlap.
When these functions are used at the same time, overlap is done at the earlier timing of this function
and rapid traverse block overlap.

- Cs contour control

When positioning is executed with the Cs contour control axis, the in-position check of the Cs
contour control axis is done even when the overlap is valid.

- Limitation

This function cannot be used with the following functions.

- Small-hole peck drilling cycle (G83) (Machining center system)
- 3-dimensional coordinate system conversion
- Tilted working plane indexing (Machining center system)
- Angular axis control
- Retrace (Machining center system)
- Manual handle retrace

Note

NOTE

1 When overlap is done between the rapid traverse block and the cutting feed

block, the feedrate might be higher than the cutting feedrate at the start position
of the cutting feed block. This is more likely to occur when the overlap time
(parameter No.1686 and No.1687) is too large againstthe time constant of the
acceleration/deceleration. In such a case, please adjust to reduce the overlap
time.

2 When the feed-forward function is used at the same time, shock may occur

between the rapid traverse block and the cutting feed block. In such a case,
please use the following servo software and validate the cutting/rapid
feed-forward switching function (bit 4 of parameter No.2214 is 1).
