Abstract: This paper establishes the simulation error data models of roundness error, spindle rotation error and noise signal from the characteristics of error signal based on three-point method. From the Matlab simulation, the influence of installation angle error of the sensor, roundness error magnitude and the noise on the segregation accuracy was studied in detail. This makes up the deficiencies of previous studies, and also provides a good foundation for further improving the accuracy of three-point method.

Abstract: This paper taken the flat-end tool and machined surface as a pair of mutually conjugate space contact tooth envelope surface and used the Frenet frame of differential geometry to describe the NC machining tool path in five-axis CNC machining of mold surface with flat-end tool. Thus the geometric model in five-axis CNC machining of mold surface with flat-end tool was established.
