Solution-region-based synthesis approach for selecting optimal four-bar linkages with the Ball–Burmester point [PDF]

open access: yesMechanical Sciences, 2019
In this paper, we present a solution-region-based synthesis approach for selecting optimal four-bar linkages with a Ball–Burmester point. We discuss both general and special cases of the Burmester point that coincide with the Ball point at the pole of ...

Simultaneous Five-axis Motion for Identifying Geometric Deviations Through Simulation in Machining Centers with a Double Pivot Head

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
In this paper, simultaneous five-axis control motions were newly proposed to identify the ten inherent deviations to double pivot head type five-axis machines. This motion was designed for the application of a ball bar to the measurements.
