Compared with the conventional drilling, helical milling has obvious advantages in making holes of carbon fiber-reinforced plastic (CFRP). Nevertheless, rapid wear cutting edges readily causes some defects outlet holes, such as burrs and tearing. In order to improve hole-making quality CFRP, a comparative experimental study on ultrasonic-assisted bi-directional CFRP was carried out. The mechani...

The implementation of condition monitoring tools can improve plant availability and lower downtime costs in general. A reliable adaptive control system prevent machine or undesired situations such as chatter vibration excessive tool wear, permitting the best utilization a tool's life. This study used dynamic force analysis to create an for Computer Numerical Control (CNC) milling adjust control...

Milling forces play an important role in the milling process and are generally calculated by mechanistic or numerical methods; reliable model of cutting is very for simulation process, which has big scientific significance to further improve machining quality. Ball helical technology used make holes based on principle using ball end cutter, due influence spherical surface characteristic, modeli...

In waterjet and laser milling, material is removed from a solid surface in a succession of layers to create a new shape, in a depth-controlled manner. The inverse problem consists of defining the control parameters, in particular, the two-dimensional beam path, to arrive at a prescribed freeform surface. Waterjet milling (WJM) and pulsed laser ablation (PLA) are studied in this paper, since a g...
