Main Factor

The ever-increasing demands of very high precision components have forced manufacturers to improve equipment to meet the demand. The main factor is the identification and compensation of errors in machine tools. In this paper, a new real-time method is presented to identify and compensate the error with space gauge, by use of which the composition of errors is directly compensated by measuring the deformation of the points in machine bed. Then, a simple single-axis machine tool is used to determine the relationship of deformation between gauging point and control point to verify the feasibility of the method. Furthermore, due to the simplicity of the implement and, the method can be easily used in an industrial production with minimal investment. Consequently, the result shows the method can be widely applied.

High Speed Machine

Experimental evidence has shown that the natural frequencies of a high-speed spindle decrease with increasing rotational speeds. While this phenomenon is important to the design and operation of high-speed machine tools, it has not been thoroughly analysed. This paper presents a spindle model that can be used to analyse the changes in bearing stiffness and the natural frequencies of the system. It is shown that the system dynamics can vary substantially due to bearing centrifugal force and shaft gyroscopic effects. The findings can be utilized in optimizing the design and control of high-speed spindle systems.
