5.5.1.7 Return along Path
The return along path function is indissociable from the backtrack along path function (see 5.5.1.6). After a backtrack
along path, the return along path returns the toolhead to the position it occupied when machining was interrupted.
Requirements
Machining interrupted (see 5.5.1.1), backtrack along path completed ("Backtrack" button released).
Actions
Cancel (immediately or later) the tool/workpiece datum shift
(see Tool/workpiece datum shift under Notes).
Press the "Return" button on the machine panel.
The return along path takes placed in the movement mode selected (see Movement mode under Notes).
In the current position page, the "TO GO" column displays the distance from the end point.
Release the "Return" button when the selected return position is reached.
Resume machining by pressing the "CYCLE" pushbutton on the machine panel.
The programme continues.
Exit from the procedure
If no tool/workpiece datum shift was programmed or this shift has been cancelled (see Tool/workpiece datum shift
under Notes), machining can be resumed at any time.
Release the "Return" pushbutton.
The return movement is stopped immediately.
Press the "CYCLE" pushbutton to cancel the machining interruption.
The "INCYC" indicator comes on in the status window (see 3.1.3) and programme execution is resumed (see
Movement mode under Notes for the speed of movement). During resumption, a new machining interruption can be
requested by pressing "FEED STOP".
Notes on Return along Path
The notes for return along path are the same as for backtrack along path (see 5.5.1.6).
5.5.1.8 Cancellation of an Operation in Progress
The operation in progress can only be cancelled if no movements are being performed, i.e. in one of the following cases:
- "INCYC" indicator not displayed in automatic, single, dry run or test modes,
- "CYHLD" indicator displayed in the status window,
- feed rate potentiometer set to zero and active (the potentiometer is not active in certain machining phases such
as thread cutting),
- load mode in progress,
- unload mode in progress,
- search mode in progress,
- test mode in progress.
