Although many studies have focused on the cutting performance of ceramic blades in processing different materials, few reported their application wood processing. Thus, it is necessary to explore tools solid machining. The aims this paper were evaluate Al2O3 and Si3N4 process machining Manchurian ash (Fraxinus mandshurica Rupr.) Chinese fir (Cunninghamia lanceolata) by means analysing force sur...

In recent years, micro/nanoscale diamond cutting tools shaped by focused ion beam (FIB) has been developed to the deterministic fabrication of micro/nano-structures owing to its unprecedented merits of high throughput, one-step, and highly flexible precision capabilities. However, the exposure of a diamond tool to FIB will result in the implantation of ion source material and the irradiation da...

in this research, our attempt is to monitor tool wear through the chip formations, forces, and temperature of edge of drill while drilling in superalloy plate to optimizes effective parameters, which lead to facilitate machining process to, improved tool life, and enhance the productivity. in this study, inconel718 superalloy material, and cemented coated carbide tool was selected for investiga...

This research explores the automated process adjustments of chip cutting operations by using neural network and statistical approaches in a computer-aided vision system. Multilayer ceramic capacitors (MLCC), owing to their excellent electronic characteristics, are applied in the design of high-density PC boards. The excellences of MLCCs are accomplished through rigorous controlling of every pro...

the aim of present study is to investigate the kinematics of tool-workpiece’s relative movement in conventional and ultrasonic-vibration assisted turning (uat). the kinematic analysis of uat shows that the movement of cutting tool edge relative to the workpiece resulted from the cutting speed, feed speed and tool’s vibration affects the lateral machined surface of workepiece and leaves a repeat...

Piezoelectric fast tool servo mechanism, with its existing nonlinear response and hysteresis, restricts greatly the precision when applied to machining of non-axisymmetric optical surface. In this paper, a feed-forward control method is applied to compensate the displacement of the fast tool servo. According to the workpiece surface feature and the tool path, the mathematical model of the minim...

This work proposes a process planning for machining of a Floor which is the most prominent elemental machining feature in a 21⁄2D pocket. Traditionally, the process planning of 21⁄2D pocket machining is posed as stand-alone problem involving either tool selection, tool path generation or machining parameter selection, resulting in sub-optimal plans. For this reason, the tool path generation and...
