Advanced Curve Machining Method for 5-Axis CNC Machine Tools

A new method for curve machining on 5-axis CNC machine tools is proposed in this paper. It uses the CNC interpolator approach, or called curve interpolator, which can produce accurate tool position as well as tool orientation. The interpolator calculates a new command in real time, the same time period needed for sampling the control-loop feedback devices. It performs two steps in each sampling period: (1) trajectory planning based on a constant feedrate and (2) inverse kinematics transformation based on the structure of the machine. To implement this curve interpolator, a 3-D parametric curve g-code must be defined for 5-axis…

Applications of Computer Numerical Control (CNC) Machine in Manufacturing Industries

In today’s scenario you will find lathe machine in almost all industries, workshops and even on road side small scale workshops or repair shops for heavy vehicles. CNC lathe machines are also not an exception to this. There is hardly any aspect of manufacturing that is not handled by the automated CNC machine. It’s a must know for everyone who are involved in the manufacturing industry, what a CNC machine can do for their corporation. Because of broad applications of CNC machines in different industries, there is a great pitch in the demand of the CNC machine programmers. In order to fulfill…

Advantages & Disadvantages of CNC (Computer Numerical Control) Machine

CNC machine basically Computer Numerical Control machine which particularly points at the involvement of computers in controlling machine tools operations. Initially it may seem like a regular functioning PC; however, it is unique and well developed software that is used to control machine tools. Here, the machine tools work through the numerical control, as mentioned above. Again, the computer software or rather program that is employed is customized for an object and then the machines are programmed accordingly with the Computer Numerical Control language. This is often referred to as the G- code. Now this particular code is used to…
