Thermal error analysis and error prediction modeling on a machine tool

2008 IEEE International Conference on Industrial Engineering and Engineering Management, 2008
Thermal errors are the largest contributor to the dimensional errors of a workpiece in precision machining. It is very significant to study how to accurately simulate the spindle thermal errors. In this paper a novel concept of thermal error modes analysis is proposed to develop a better understanding of the thermal deformation on a machine tool.

Study on Machining Error of Globoidal Cam Profile Resulting from Motion Error of Machine Tool in Machining

Applied Mechanics and Materials, 2011
The profile error of a globoidal cam resulting from motion errors of two coordinated rotational axes of a machine tool in machining is studied. A novel method of solving profile error is presented. According to this method, the minimum distance from a point on the profile actually machined to the desired profile is referred to as the profile error ...

Computer-aided error modeling of machine tool

International Conference on Advanced Technology of Design and Manufacture (ATDM 2010), 2010
Error modeling is the basis of error identification and error compensation of mechanical tools. Traditional error modeling methods are completely done by human. The process is complex and takes long time. The models are difficult to adjust and fit the changeable structure of modern modular machine tools once they have been built. To make error modeling
