In the contemporary Computer Numeric Controlled (CNC) machine tools of Computer Aided Manufacturing (CAM) and CNC process conducted by a number of inter-related operations and parameters using G Codes and M codes set as RS274 or ISO 6983 standard. However, this programming language does not explicitly relate to each other to have control of arbitrary locations other than the motion of the block...

Due to its high precision, productivity, and surface quality, computer numerical control turning (CNC) is a desirable processing tool in the traditional area. CNC machining procedures have huge number of process parameters, making it challenging find best combination parameters for increased accuracy. In this research work, Taguchi method ANOVA were used study effects EN8 steel turning: Surface...

The effect of cutting tool insert geometry has significant role for surface finish in turning operation. There are many different types of tool inserts with different tool insert geometry are used in turning operation. This paper present a logical procedure to select best tool insert from alternative tool inserts for better surface finish in turning operation. The procedure based on three well ...

This paper presents the optimization of CNC turning parameters for EN 16 steel bar using the Grey Taguchi Method. A plan of experiments based on Taguchi’s L27 orthogonal array was established and turning experiments were conducted with prefixed cutting parameters for EN 16 steel bar using tungsten carbide tool. The turning parameters are cutting speed, feed rate and depth of cut and the respons...

In-process measurement and control of CNC machines can improve machining accuracy while increasing productivity and eliminating waste in a cost effective way. This paper describes an in-process measurement and control system called radial error feedback geometric adaptive control (REFGAC) system for bar turning in CNC turning centers. REFGAC system was design to compensate for the radial error ...

A tool adaptor with built-in active vibration damping device to dynamically stabilize the turning process is presented in this paper. It can be used in standard CNC-lathes and allows the usage of off-the-shelf tool heads. The vibration compensation system is based on a multilayer piezoactuator that is in collocation with a piezoelectric force sensor. An analogue controller based on the integral...
