According to one implementation, an attachment for a machining apparatus includes: a copying guide in a machining apparatus side and an air supply passage. The copying guide has a through hole for passing a tool through. The copying guide is contacted to a copying mold placed in a workpiece side. The copying guide is attached to a spindle holding and rotating the tool. The air supply passage is adapted to supply air ejected toward the workpiece side through a clearance between the tool and the through hole.

A method for compensating for the deflection of a milling cutter during the machining of a workpiece by a numerically controlled machine tool having a plurality of axes includes: executing a learning cut on a test workpiece having a known geometry by the milling cutter mounted on a tool spindle in a climb milling mode, and in doing so, ascertaining a correlation between a quantity that is proportional to the torque of the drive of the tool spindle and the deflection of the milling cutter normal to a surface of the test workpiece, the deflection being determined by comparing the actual contour of the test workpiece to a setpoint contour. This is followed by storing of the correlation for the milling cutter and machining of the workpiece by the milling cutter in a climb milling mode, while utilizing the stored correlation for compensating for the deflection of the milling cutter by applying a positional correction that is proportional to the quantity to a setpoint position of the axes of the machine tool.

Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. The pantograph armature includes a motorized drive shaft with a drill tip for carving an outside surface of a crayon body, as well as a guide tip for tracing along a guide template that directs where the drill tip carves. In some embodiments, the guide template includes a stationary bridge support and a plurality of removable carving bucks that insert into one of multiple openings on the bridge support. The surface features of each of the carving bucks may be traced by the guide tip to generate a corresponding carving on the surface of a crayon body.

Each type of metal component part for two or more watch designs can be derived from instances of that corresponding type of MIM blank for that component part, which is formed from a same injection molding tool (respectively for each type of component part). An example instance of the MIM blank formed for a type of component part then has at least a portion of the instance of the MIM blank subtracted through a CNC milling process to form an interim shape and geometry of an instance of the type of component part for a given watch design. The CNC milling process can be applied to the MIM blank for that component part when the MIM blank is in its interim shape and geometry and has not yet been hardened to a finished shape and geometry of an instance of that type of component part for the watch design.
