The Retract application
Application
The Retract application allows you to disengage the tool from the workpiece after an interruption in power (e.g., retraction of a tap engaged in the workpiece).
You can also retract a tool when the working plane is tilted or retract an inclined tool.
Requirement
- This application must be enabled by your machine manufacturer.
The machine parameter retractionMode (no. 124101) allows the machine manufacturer to define whether the control will display the Retract toggle switch during start-up.
Description of function
The Retract application provides the following workspaces:
- Retract
- Positions
- Status
The Retract application provides the following buttons in the function bar:
Button | Meaning |
---|---|
Retract | Retract the tool with the axis keys or the electronic handwheel |
End retraction | Close the Retract application The control opens the End retraction? window and prompts you to answer a confirmation request. |
Start values | Reset the entries in the A, B, C, and Thread pitch fields to their original values |
You select the Retract application by using the Retract toggle switch if the following conditions apply during start-up:
- Power interrupted
- No control voltage for the relay
- The Move to ref. point application
If you have activated a feed rate limit before the power failure occurred, this feed rate limit will still be active. When you select the Retract button, the control will display a pop-up window: This window allows you to deactivate the feed rate limit.
The Retract workspace
The Retract workspace provides the following contents:
Row | Meaning |
---|---|
Traversing mode | Traverse mode for retraction:
|
Kinematics | Name of the active machine kinematics |
A, B, C | Current position of the rotary axes Effective in the Tilted system traverse mode |
Thread pitch | Thread pitch from the PITCH column of tool management Effective in the Thread traverse mode |
Direct. of rotation | Direction of rotation of the thread-turning tool:
Effective in the Thread traverse mode |
Coordinate system for handwheel superimposition | Coordinate system in which handwheel superimpositioning takes effect Effective in the Tool axis traverse mode |
The control selects the mode of traverse and the associated parameters automatically. If the traverse mode or the parameters have not been correctly preselected, you are able to reset them manually.
Notes
- Use a low feed rate
- Please keep in mind that the traverse range monitoring is not available for non-referenced axes
- Use the +, -, *, /, (, and ) keys for calculations in the numerical input fields.
Example
The power failed while a thread cutting cycle in the tilted working plane was being performed. You have to retract the tap:
