A system, method, and device for automated precision control of a computer numerical control (CNC) machine to a workpiece. The system receives via at least one visual input device at least one detectable marking on a workpiece. The system decodes the at least one detectable marking and determines a stored and pre-defined movement routine of a cutting element attached to the CNC machine relative to the workpiece based on the at least one marking. The system then determines, using the at least one visual input device and/or another visual input device, a current position of a working end of the cutting element relative to the at least one marking. Finally, the system performs the pre-defined movement routine including cutting into the workpiece with the cutting element.

Disclosed is a method for an all-laser hybrid additive manufacturing. After a matrix is obtained by means of selective laser melting forming, a subtractive forming is carried out on the matrix by means of a pulse laser to form a cavity, and the cavity is then packaged to obtain a forming material with an internal cavity structure. A laser precision packaging method is used in the method based on the melting of the laser selective region. Also disclosed is the apparatus, comprising a laser unit (2), a control unit (4) and a forming unit (6).

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.
