Errors of the rotary axes are the main sources of geometric errors in a five-axis machine tool. Thus, accurate periodic checks and calibrations of the rotary axes are important for improving the machining precision. In this paper, to achieve error detection with three-dimensional (3D) measurement capability and to simplify the complex error identification formulations of position-independent geometric...
Contouring error detection for machine tools can be used to effectively evaluate their dynamic performances. A triangular vision-based contouring error detection system and method is proposed in this paper, realizing the three-dimensional error measurement of an arbitrary trajectory in conditions of a high feed rate and wide motion range. First, a high-precision measurement fixture, which consists...
