Abstract
The invention relates to a method for machining a workpiece by means of a milling tool arranged on a rotatable spindle, the spindle being moved relative to the workpiece or the workpiece being moved relative to the spindle along a machining path and, at the same time, the spindle rotating about a spindle axis. In said method, an improvement in the surface quality is achieved by controlling the rotational speed and/or the phase position of the rotation of the spindle along the machining path, the machining path comprising linear parallel tracks and the phase position of the spindle along the machining path being substantially the same on adjacent tracks, the phase position being controlled by varying the rotational speed of the spindle and/or the advancing speed of the spindle relative to the workpiece along the machining path.
Claims11
A method for machining a workpiece with a milling tool arranged on a rotatable spindle, the method comprising:
- moving the spindle relative to the workpiece or moving the workpiece relative to the spindle along a machining path;
- rotating the spindle about a spindle axis;
- and
- controlling the spindle along the machining path such that the machining path comprises linear parallel paths along the workpiece having synchronized spindle control by:
- analyzing a portion of the machining path prior to executing the portion of the machining path, the analysis determining a synchronous point along the analyzed portion of the machining path, the synchronous point being a position along the analyzed machining path where a spindle phase is to be the same as a previous spindle phase achieved along at least one of the linear parallel paths, and
- prior to reaching the synchronous point, varying the rotational speed of the spindle and/or the feed rate of the spindle relative to the workpiece along the analyzed portion of the machining path to adjust the spindle phase to be the same as the previous spindle phase at the synchronous point.
