Optimization method for complex surface partitioning and cutting parameters in 5-axis machining [PDF]
For complex surfaces with variable geometric features and high processing requirements, the current stage still uses more conservative machining cutting parameters to generate five-axis machining tool positions, which inevitably leads to some parts not ...

Feasibility of 8-Shaped Motion Test for Five-Axis Machining Center
ISO 10791-7, which specifies the machining accuracy test standard for machining centers, and ISO 10791-6, which specifies the interpolation motion test standard, were revised in 2014 to include five-axis machining centers (5-axis MCs). In addition, cone frustum test, which has been used as the National Aerospace Standard (NAS), was revised and ...

Investigation on Finished Surface Machined by Five-axis Machining Center
This study describes the machining of the fine surfaces with a ball nose end-mill tool by a five-axis controlled machining center. In the present paper, we demonstrate that it is effective to maintain a constant contact angle between an end-mill ball nose and a work surface in machining in order to obtain the fine machined surface because this makes it

Analysis of Generating Motion for Five-Axis machining Centers.
This paper deals with the theoretical investigation of the arrangement of slideways for five-axis machining centers. There is a considerable number of combinations with respect to the five-axis slideways. However, a critical assessment of the possible combinations of slideways has not been performed so far.

Measurement of Synchronous Motion in Five-axis Machining Centers
This paper describes a newly proposed method for evaluating the synchronous inaccuracy of the translational and rotational axes in five-axis controlled machining centers. The circular motion of which shape is easy to evaluate is adopted for measuring the trajectory described by the axes in the proposed method.
