Image-Based Placing of Workpiece Machining Operations

A processing machine for machining workpieces, the processing machine comprising:

• at least one image capturing device arranged to perform a two-dimensional capture, from a three-dimensional perspective, of an image of a workpiece to be machined;
• a transformation unit arranged to perform forward and inverse transforming between a three-dimensional machine coordinate system and a two-dimensional live-image coordinate system;
• a monitor arranged to display a live image of the workpiece to be machined and to display a result preview from the three-dimensional perspective of a workpiece machining operation to be performed;
• an operator control unit arranged to reposition the workpiece machining operation to be performed in the live image;
• and
• a machine control programmed to control workpiece machining, including performing the workpiece machining operation on the workpiece, wherein the workpiece machining operation is performed by a predetermined inverse transformation of the repositioned workpiece machining operation from the two-dimensional live-image coordinate system into the three-dimensional machine coordinate system.

One or more computer-readable storage media storing instructions which, when executed by at least one computer, instruct the at least one computer to perform operations comprising:

• receiving a live image of a workpiece to be machined, the live image captured with an image capturing device for capturing two-dimensional images, wherein the live image of the workpiece to be machined is captured with the image capturing device from a three-dimensional perspective and displayed from the three-dimensional perspective;
• displaying at least one workpiece machining operation to be performed as a result preview in the live image of the workpiece, wherein the at least one workpiece machining operation to be performed is displayed by a predetermined forward transformation of the at least one workpiece machining operation from a three-dimensional machine coordinate system into a two-dimensional live-image coordinate system;
• repositioning the at least one workpiece machining operation to be performed in the live image of the workpiece;
• and
• performing the at least one workpiece machining operation on the workpiece, wherein the at least one workpiece machining operation is performed by a predetermined inverse transformation of the at least one repositioned workpiece machining operation from the two-dimensional live-image coordinate system into the three-dimensional machine coordinate system.
