Overview
Depending on the entry for parameter Q560 you can either activate (Q560=1) or deactivate (Q560=0) the COUPLG.TURNG.INTERP. cycle.
Spindle coupling off, Q560=0
The tool spindle is not coupled to the position of the linear axes.
Tip
Q560=0: Disable the COUPLG.TURNG.INTERP. cycle!
Spindle coupling on, Q560=1
A turning operation is executed with the tool spindle coupled to the position of the linear axes. If you set the parameter Q560=1, there are different possibilities to define the tool in the tool table. This section describes the different possibilities:
- Define a turning tool in the tool table (tool.t) as a milling tool
- Define a milling tool in the tool table (tool.t) as a milling tool (for subsequent use as a turning tool)
- Define a turning tool in the turning tool table (toolturn.trn)
These three possibilities of defining the tool are described in more detail below:
- Define a turning tool in the tool table (tool.t) as a milling tool
If you are working without option 50, define your turning tool as a milling cutter in the tool table (tool.t). In this case, the following data from the tool table are taken into account (including delta values): length (L), radius (R), and corner radius (R2). The geometry data of the turning tool are converted to the data of a milling cutter. Align your turning tool to the spindle center. Specify this spindle orientation angle in parameter Q336 of the cycle. For outside machining, the spindle orientation equals the value in Q336, and for inside machining, the spindle orientation equals Q336+180.
Notice
Danger of collision!
Collision may occur between the tool holder and workpiece during inside machining. The tool holder is not monitored. If the tool holder results in a larger rotational diameter than the cutter does, there is a danger of collision.
- Select the tool holder to ensure that it does not result in a larger rotational diameter than the cutter does
- Define a milling tool in the tool table (tool.t) as a milling tool (for subsequent use as a turning tool)
You can perform interpolation turning with a milling tool. In this case, the following data from the tool table are taken into account (including delta values): length (L), radius (R), and corner radius (R2). Align one cutting edge of your milling cutter to the spindle center. Specify this angle in parameter Q336. For outside machining, the spindle orientation equals the value in Q336, and for inside machining, the spindle orientation equals Q336+180.
- Define a turning tool in the turning tool table (toolturn.trn)
If you are working with option 50, you can define your turning tool in the turning tool table (toolturn.trn). In this case, the orientation of the spindle to the center of rotation takes place under consideration of tool-specific data, such as the type of machining (TO in the turning tool table), the orientation angle (ORI in the turning tool table), parameter Q336, and parameter Q561.
Tip
- Programming and operating notes:
- If you define the turning tool in the turning tool table (toolturn.trn), we recommend working with parameter Q561=1. This way, you convert the data of the turning tool into the data of the milling tool, thus greatly facilitating your programming effort. With Q561=1 you can use radius compensation RR and RL when programming. (However, if you program Q561=0, then you cannot use radius compensation RR and RL when describing your contour. Additionally, you must program the movement of the tool center path TCP without spindle coupling. This kind of programming is much more complicated!)
- If you programmed parameter Q561=1, you must program the following in order to conclude the interpolation turning machining operation:
- R0, cancels radius compensation
- Cycle 291 with parameters Q560=0 and Q561=0, deactivates spindle coupling
- CYCL CALL, for calling Cycle 291
- TOOL CALL overrides the conversion of parameter Q561
- If you programmed parameter Q561=1, you may only use the following types of tools:
- TYPE: ROUGH, FINISH, BUTTON with the machining directions TO: 1 or 8, XL>=0
- TYPE: ROUGH, FINISH, BUTTON with the machining directions TO: 7: XL<=0
The spindle orientation is calculated as follows:

- You can use the following tool types for interpolation turning:
- TYPE: ROUGH, with the machining directions TO: 1, 7, 8
- TYPE: FINISH, with the machining directions TO: 1, 7, 8
- TYPE: BUTTON, with the machining directions TO: 1, 7, 8
- The following tool types cannot be used for interpolation turning:
- TYPE: ROUGH, with the machining directions TO: 2 to 6
- TYPE: FINISH, with the machining directions TO: 2 to 6
- TYPE: BUTTON, with the machining directions TO: 2 to 6
- TYPE: RECESS
- TYPE: RECTURN
- TYPE: THREAD
