Tapping without compensating chuck
This function allows threads to be tapped without a compensating chuck. By using the interpolating method of the
spindle as a rotary axis and the drilling axis, threads can be cut to a precise final drilling depth, e.g. for blind hole
threads (requirement: spindles in axis operation).

TOA area
The TOA area includes all tool and magazine data. By default, this area coincides with the → channel area with
regard to the reach of the data. However, machine data can be used to specify that multiple channels share one
→ TOA unit so that common tool management data is then available to these channels.
TOA unit
Each → TOA area can have more than one TOA unit. The number of possible TOA units is limited by the
maximum number of active → channels. A TOA unit includes exactly one tool data block and one magazine data
block. In addition, a TOA unit can also contain a toolholder data block (optional).
Tool
Active part on the machine tool that implements machining (e.g. turning tool, milling tool, drill, LASER beam,
etc.).
Tool nose radius compensation
Contour programming assumes that the tool is pointed. Because this is not actually the case in practice, the
curvature radius of the tool used must be communicated to the control which then takes it into account. The
curvature center is maintained equidistantly around the contour, offset by the curvature radius.
Tool offset
Consideration of the tool dimensions in calculating the path.
Tool radius compensation
To directly program a desired → workpiece contour, the control must traverse an equistant path to the
programmed contour taking into account the radius of the tool that is being used (

Transformation
Additive or absolute zero offset of an axis.
