Five-axis milling machine tool kinematic chain design and analysis

International Journal of Machine Tools and Manufacture, 2002
Five-axis CNC machining centers have become quite common today. The kinematics of most of the machines are based on a rectangular Cartesian coordinate system. This paper classifies the possible conceptual designs and actual existing implementations based on the theoretically possible combinations of the degrees of freedom.

Trajectory analyses for five-axis machine tools

2010 IEEE Conference on Robotics, Automation and Mechatronics, 2010
In order to achieve high accuracy, less machining time, and more machining variety, normally, additional two rotary axes are set up on top of traditional three- axis CNC machine tool, which is called five-axis machines. The tool motion for five-axis machines in this research includes both translating and rotating axis movements simultaneously.

Tool path planning for aspheric five-axis machine tools

AOPC 2019: Optical Spectroscopy and Imaging, 2019
Aspheric surfaces are widely used in modern optical systems. At present, five-axis machine tools are widely used for aspheric surfaces grinding and shaping. The technology of milling aspheric surface with five-axis machine tool is studied. According to the B-C double turntable five-axis machine tool, its kinematics model is analyzed.

Ruled Surface Machining on Five-Axis CNC Machine Tools

Journal of Manufacturing Processes, 2000
Abstract To achieve high precision and high productivity in machining sculptured surfaces, a new architecture for a five-axis CNC interpolator for machining ruled surfaces was developed and demonstrated on a milling machine. The objective of the five-axis interpolator is to continuously maintain the milling cutter axis in parallel with the straight ...

Smooth Geodesic Interpolation for Five-Axis Machine Tools

IEEE/ASME Transactions on Mechatronics, 2016
The smoothness of tool trajectories would be as important as that of axis trajectories for five-axis machining. The present study proposes a geodesic interpolation for five-axis machine tools. The tool positions and orientations are fitted to geodesics, respectively, to achieve smooth accurate motions of the tool center point (TCP), smooth axis motions,

Tool selection for five-axis curvature matched machining

Computer-Aided Design, 2002
This paper presents an automatic cutting tool selection methodology for five-axis finish surface machining based on the techniques of curvature matched machining. The criterion for cutter selection is to minimize the machine errors and to maximize material removal rate using an optimal filleted end mill selected from a standard cutting tool library ...

Smooth trajectory generation for five-axis machine tools

International Journal of Machine Tools and Manufacture, 2013
Abstract This paper presents a smooth spline interpolation technique for five-axis machining of sculptured surfaces. The tool tip and orientation locations generated by the CAM system are first fitted to quintic splines independently to achieve geometric jerk continuity while decoupling the relative changes in position and orientation of the cutter ...

Five-Axis Machining Tool Vector Control of Impeller

Key Engineering Materials, 2009
There are two key problems in the manufacture process of impeller, one is the collision of tool and blade, the other is gnawed-cutting arisen by non-uniform change of the cutter axis. UG software was used to solve those problems. Tool tip position was solved by UG. The control algorithm of collision-free cutter-axis was described and applied.

Repeatability of on-machine probing by a five-axis machine tool

International Journal of Machine Tools and Manufacture, 2020
Abstract Assessing the repeatability of on-machine probing is required to estimate the measurement uncertainty. Currently, standards such as ISO 230–2:2014 and ISO 230–6:2002 include approaches only for a single-axis or a diagonal-path evaluation of the machine repeatability.
