A material removing machining module for a machine tool including: a part support intended to receive a part to be machined, a control unit of the part support adapted to control and to modify the position of the part support in the machining module, a toolholder intended to receive a tool having an end portion used for machining the part; a control unit of the toolholder adapted to control and to modify the position of the toolholder in the machining module, a unit for detecting the profile of the tool mounted on the toolholder, which includes an optical system mounted on the toolholder for determining the profile of said end portion of the tool mounted on the toolholder.

A motion mechanism moves a workpiece relative to a cutting tool with a convex cutting edge. A controller controls the relative movement between the workpiece and the cutting tool by the motion mechanism and an orientation of the cutting tool. The controller intermittently or continuously changes the orientation of the cutting tool to cause a part of the cutting edge that has not been used for cutting to form a finished surface.

A process for operating a virtual sensor for determining the condition of a tool holder on a tool machine, such as a spindle, and the condition of a tool machine which has at least one tool holder and at least one tool, attached or attachable to the tool holder, which allows a workpiece to be processed by running a machine program, and which has at least one control unit comprising at least one sensor.

A machining system includes a machine tool having a camera, and a three-dimensional shape generating apparatus. The three-dimensional shape generating apparatus includes an image capture unit that captures a first image from the camera at a first relative position and captures a second image from the camera at a second relative position, and a shape generator that generates a three-dimensional shape of at least one subject, based on the first image, the second image and a distance between the first relative position and the second relative position.

A disclosed method utilizes virtual representations of gear profiles produced in view of accuracies and capabilities of specific machine and tool combinations to validate profile finishing parameters. The virtual representations are utilized to identify modifications needed to account for process capability and are implemented into the process to change the nominal profile utilized for producing the finished gear profiles. The resulting nominal gear profile accounts for process variations and thereby provides a more accurate and repeatable gear tooth profile.
