Procedure 3
1 Return the mode selection switch to the mode that was active
before automatic operation was interrupted. The block return
switch turns ON if it was OFF. (The letters "RSTR" may be
displayed or blink on the status line of the screen depending on the
machining conditions.)
2 Press the Cycle Start button.
3 The cycle start lamp lights, and automatic operation is restarted.
Then, the block return switch is turned OFF.
Explanation
- Manual operation with the block return switch turned on
Move the tool in the continuous manual feed mode toward the start
point of
the interrupted block while the block return switch is on. The tool
automatically stops at the start point. When the start point is reached
for all axes, the message RSTR disappears from the bottom of the
screen.
If the block return switch is turned on in the continuous manual feed
(JOG) mode, the distance between the current position of the tool and
the start point of the interrupted block is calculated. The start point of
the interrupted block refers to the point calculated as follows:
Absolute coordinate of the programmed start point
+
Previously compensated tool value
+
Newly calculated tool length compensation value
=
Newly calculated cutter compensation value perpendicular to the
interrupted block at the start point
If the tool offset value is changed, new compensation values (vectors)
for the tool length compensation (G43 and G44) for the fixed
compensation axis (bit 4 (LXY) of parameter No. 6000 is set to 0) and
the cutter compensation (G41 and G42) are calculated based on the
new offset value. However, the compensation values for the tool length
compensation for an arbitrary compensation axis (bit 4 (LXY) of
parameter No. 6000 is set to 1) and the tool offset (G45 to G48) remain
unchanged.
The calculated distance to the start point is displayed by pressing the
[BLOCK RESTRT] soft key on the position display screen. Normally,
when the block return switch is turned on in jog feed (JOG) mode, this
screen (called the restart display) appears automatically. On the restart
display screen, the following values are indicated.
