Standard turning functions

Standard turning functions are used for conventional turning work with an endlessly rotating spindle. A position-controlled interpolated CNC spindle axis must be configured as the main spindle to achieve the full scope of functions. For details see [FCT-S1].

The tool-carrying spindle axis is commanded at the assigned speed by the spindle commands M03, M04 and M05.

A longitudinal and a face turning axis must be identified by an entry in the axis parameter P-AXIS-00015. The figure above shows an example where the Z axis is marked as the longitudinal turning axis (bit 0x80) and the X axis as the face turning axis (bit 0x40).

The conventional axis configuration consists of 3 Cartesian main axes in the order X-Y-Z (1st main axis, 2nd main axis, 3rd main axis). Machining is executed in the programmed G18 plane (Z, X).

	Recommendation: Configuration of the main axes X-Y-Z and machining in the G18 plane.

Machining can also be executed in the default G17 plane. The alternative axis configuration must then be Z-X-Y.
