Performance of Five-Axis Machine Tool and Intelligent Machining Process [PDF]
, 2021 Abstract In this study, the processing performance of a five-axis machine tool was analyzed to identify processing weaknesses as the basis for subsequent structural improvements. Data were then integrated through the Abductory Induction Mechanism (AIM) polynomial neural network to predict intelligent processing quality, and an in-depth ...

Tool-path planning method for kinematics optimization of blade machining on five-axis machine tool
The International Journal of Advanced Manufacturing Technology, 2022 Abstract Planning tool-paths on free-form surfaces is a widely discussed issue. However, traditional methods of generating paths capable of meeting all the requirements of blade machining remain challenging. In this study, a new iso-parametric path-planning strategy based on a novel parameterization method combined with the conformal ...

Influence of Tool Length and Profile Errors on the Inaccuracy of Cubic-Machining Test Results
Journal of Manufacturing and Materials Processing, 2021 A cubic-machining test has been proposed to evaluate the geometric errors of rotary axes in five-axis machine tools using a 3 × 3 zone area in the same plane with different tool postures. However, as only the height deviation among the machining zones is

Machining tests to identify kinematic errors on five-axis machine tools [PDF]
Precision Engineering, 2010 Abstract The machining of a cone frustum as specified in National Aerospace Standard (NAS) 979 is widely accepted as a final performance test for five-axis machining centers. Although it gives a good demonstration of the machine’s overall machining performance, it is generally difficult to separately identify each error source in the machine from the

Motion and Virtual Cutting Simulation System for a Five-Axis Virtual Machine Tool
International Journal of Automation and Smart Technology, 2011 Since five-axis machine tools are very costly and their use requires a high level of knowledge and expertise, a virtual machine tool must be used to simulate five-axis machine tool operation. Configuration code or a mechanism topology matrix must be used
