Abstract
A machine tool (20) for machining a gearwheel workpiece (1), having: a tool spindle (21) for fastening a tool (2), a workpiece spindle (22) for fastening the gearwheel workpiece (1), a CNC controller (50) and multiple axes for the CNC-controlled machining of the gearwheel workpiece (1) using the tool (2), an optical detector (40) to acquire image information (BI) of the gearwheel workpiece (1), and a module (51), which is designed to ascertain characteristic actual parameters of the gearwheel workpiece (1) based on the image information (BI) of the gearwheel workpiece (1).
Claims12
A method comprising:
- machining a toothed gearwheel workpiece using a machine tool including a sensor configured to acquire geometry information, a tool located on a tool spindle, and a workpiece spindle, wherein the gearwheel workpiece is located on the workpiece spindle, and the method includes the following steps:
- a) acquiring, with a sensor including an optical detector, image information of the gearwheel workpiece without physical contact of the sensor therewith,
- b) ascertaining at least one characteristic actual parameter of the gearwheel workpiece based on the image information,
- c) machining at least one flank of the gearwheel workpiece using the tool, wherein said machining includes moving the tool into a tooth gap of the gearwheel workpiece without contact therewith using said at least one characteristic actual parameter, wherein the at least one flank is machined by relative movement of the tool and the gearwheel workpiece.
A machine tool for machining a gearwheel workpiece, comprising:
- a tool spindle configured for fastening a tool thereto;
- a workpiece spindle configured for fastening a gearwheel workpiece thereto;
- and
- a CNC controller;
- wherein the machine tool defines multiple axes configured for use for CNC-controlled machining of the gearwheel workpiece using the tool, and further includes
- an optical detector adapted to acquire image information of a gearwheel workpiece, and
- a module configured to ascertain at least one characteristic actual parameter of a gearwheel workpiece based on such image information.
