The Application of PLC to CNC Machine Tools Development
2011 Second International Conference on Digital Manufacturing & Automation, 2011Introduce a CNC system for nonstandard machine tool based on PLC and programmable multi-axis controller, which is appLied to CNC machine. Comparing with traditional CNC system, the proposed design has not only simpLified machine tool structure and control system, but also make user's program simpLification.

An Adaptive CNC System of a Milling Machine Tool
IFAC Proceedings Volumes, 1977Abstract An adaptive CNC(computer numerical control) system of a milling machine tool using a precise tool wear rate model is presented. In the system, the bending moments on the spindle are sensed and used for computing the fundamental parameters of cutting conditions such as work material hardness, cutter sharpness, and others.

INTERPOLATOR FEATURES FOR CNC SYSTEMS OF MACHINE TOOLS
IFAC Proceedings Volumes, 1980Abstract Most interpolators used in CNC systems of machine tools are based on the DDA principle. Most of such devices provide linear and circular interpolation with constant path velocity. The use of microprocessors in recent CNC systems has rendered it possible to implement more sophisticated interpolation features, such as modified path generation ...

Application of Tool Compensation in CNC Machining
Materials Science Forum, 2014Tool compensation determines the machining precision and quality . There are tool length compensation,tool radius compensation and corner radius compensation in CNC system .The parameters of these compensation are all static.The purpose of this study was that the machining precision and quality were improved by changing the parameters of tool ...

Reliability analysis of CNC machine tools
Reliability Engineering, 1982A reliability and maintainability study of computer control (CNC) machine tools is described. For this analysis field failure data collected over a period of three years on approximately 35 CNC machine tools during their warranty period were analysed. In order to apply quantitative reliability methods, a coding system was devised to code failure data ...

Geometric accuracy of CNC machine tools
Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014, 2014The present article is dedicated to the identification and interpretation of geometric errors of CNC machine tools. Identification of geometric errors plays a large role in the construction of the so-called “Error maps”. These maps can be used to describe the behaviour of the machine in the workspace without load or under conditions of finishing ...
