Research on a Five-Axis Machining Center Worktable with Bionic Honeycomb Lightweight Structure. [PDF]
Materials (Basel), 2020 The processing of high-precision aerospace parts requires not only ultra-precision machine tools, but also high-efficiency processing. However, in order to realize high-efficiency processing, besides optimizing the system and process parameters, some subversive research can also be done on the machine tool structure.

Prediction and compensation of machining geometric errors of five-axis machining centers with kinematic errors [PDF]
Precision Engineering, 2009 Kinematic errors due to geometric inaccuracies in five-axis machining centers cause deviations in tool positions and orientation from commanded values, which consequently affect geometric accuracy of the machined surface. As is well known in the machine tool industry, machining of a cone frustum as specified in NAS979 standard is a widely accepted ...
