A safety system for a power miter saw comprises a support member, at least one multidirectional manipulator including a workpiece holder member moveably mounted to the support member for securing a workpiece in place, and a control box. The workpiece holder member includes a presence indicator operatively connected to the control box and configured to detect the physical presence of a saw operator's hand on the at least one multidirectional manipulator when the saw operator's hand engages the presence indicator. The control box is operatively connectable to a trigger switch of the power miter saw so that an electric motor of the power miter saw is activated only when both the presence indicator of the safety system and the trigger switch of the power miter saw are engaged by both hands of an operator of the power miter saw.

A tool state learning device has a storage unit for storing an arbitrary image captured by an imaging device imaging a machined surface of an arbitrary workpiece cut using an arbitrary tool, and a teacher data acquisition unit for acquiring, as input data, an arbitrary image stored in the storage unit, and acquiring, as a label, the state of the tool annotated according to prescribed levels indicating the degree of wear of the tool on the basis of the arbitrary image. The tool state learning device also has a tool state learning unit for using the acquired label and input data to perform supervised learning, and generating a learned model in which a machined surface image of the machined surface of a workpiece imaged by the imaging device is inputted and the state of the tool that cut the machined surface of the workpiece is outputted.

A device for processing spectacle lenses has a work chamber, which is accessible by way of an opening and in which a workpiece mount and at least one tool mount are opposite one another and movable relative to one another so that a processing region of a tool held at the tool mount can be brought into processing engagement with a workpiece held at the workpiece mount and in processing engagement can be guided over the workpiece. For recognition of wear at the tool, a sensor equipment with at least one contactlessly operating sensor arrangement is provided and is movable outside the work chamber between a protected rest position and a detecting position. In the detecting position the sensor equipment is constructed to detect at the processing region of the tool held at the tool mount an unacceptable deviation beyond a predetermined amount from a desired geometry.

A method and system for optimal control of ultra-precision cutting. The method for optimal control is based on time-precipitates-temperature characteristics of Al—Mg—Si series aluminum alloy, and includes first determining types of precipitates of machined materials, and establishing a Lifshitz-Slyozov-Wagner (LSW) model of each precipitate. A temperature range is determined corresponding to each precipitate according to the LSW model to obtain a comprehensive temperature range. A relation model is established between cutting parameters and a cutting temperature according to the LSW model. Finally the cutting parameters are optimized according to the comprehensive temperature range and the relation model, so that the cutting temperature is beyond the comprehensive temperature range to inhibit the generation of the precipitates.

An apparatus for provisioning, in particular automatically, a complete tool having a toolholder and a tool, in particular a drilling and/or milling tool. The apparatus has a spindle that can be driven in rotation by a driving device. The spindle has a holding device for holding a toolholder. A measuring device, in particular an optical measuring device, measures a complete tool, held on the spindle. A heating device in the region of the spindle heats a shrink-fit chuck of the toolholder held on the spindle. A cooling device, in particular a cooling device associated with the spindle, enables the spindle and/or the complete tool held on the spindle, to be cooled.

According to one implementation, a feeding device of a hole inspection device having a probe includes an attaching jig, a movement mechanism, and a positioning jig. The probe is inserted into a hole to be inspected of an object in a central axis direction of the hole, for inspecting the hole. The attaching jig attaches the hole inspection device to the feeding device. The movement mechanism linearly reciprocates the hole inspection device together with the attaching jig. The positioning jig positions the movement mechanism to the object. A moving direction of the attaching jig and the hole inspection device is made parallel to the central axis direction of the hole by positioning the movement mechanism.
