Today, manufacturing technologies are developing within the Industry 4.0 concept, which is information introduction in manufacturing. One of most promising digital finding more and application a twin. A twin an ensemble mathematical models technological process, exchanges with its physical prototype real-time. The paper considers example formation several interconnected predictive modules, part...

Due to continuous tool engagement, turning processes tend form long chips when machining ductile materials. These chip shapes have a negative influence on process performance and productivity. One approach improve breakage is superimposition of vibrations in feed direction the process, which leads modulation uncut thickness. In joint industrial project with Schaeffler Technologies AG & Co. ...

According to turning instead of grinding process requirements and traditional working principle of ultrasonic vibration turning, a new idea of imitating grinding of two-dimensional ultrasonic vibration turning is brought firstly, and the mechanism of two-dimens ional ultrasonic vibration turning is elaborated. Based on the MATLAB software, grinding trajectory simulation and honing trajectory si...
