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 ...

Workpiece Setup Simulation based on Machinable Space of Five-axis Machining Centers
AbstractAn actual machining center specification, e.g. the axes travel, the workpiece size allowance, etc., needs to be considered for constructing a machining process plan. In this paper, a machinable space of a five-axis machining center is proposed for simulating the workpiece setup.

Thermal Characterization and Predictive Modeling of Thermo-Elastic Errors in Five-Axis Machining Centers Using Dynamic R-Test [PDF]
Five-axis machining centers are essential for manufacturing complex, high-precision parts. However, their accuracy is significantly affected by thermally induced geometric errors, also known as thermo-elastic errors.

Identification of Alignment Errors in Five-Axis Machining Centers Using Telescoping Ball Bar.
This paper deals with the identification of alignment errors in five-axis machining centers. There are thirteen alignment errors in each five-axis machining center. Three alignment errors in the three translational slideways are identified by circular tests using a Telescoping Ball Bar.
