Research on tool path planning for five-axis machining

2009 IEEE International Conference on Industrial Engineering and Engineering Management, 2009
Tool path planning of CNC motion controller includes tool path interpolation and velocity planning. Five-axis machine tools have been adopted in mold surface and aerospace part machining. In this paper, the kinematics frame based on dual quaternion D-H representation was applied to define the coordinates of five-axis machines systematically ...

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,

Five-Axis Curve Machining for Computer Control Machine Tools

2011
Five-axis machining has been widely used in aerospace, automobile and mold/die industries. It has many advantages compared to conventional three-axis machining, including higher metal removal rates, better surface finish, and more precise part surface in one setup.

Modeling and Compensation for Five-Axis Machine Tool Errors

Manufacturing Science and Engineering: Volume 2 — Non-Traditional Design and Layered Manufacturing; Rolling Technology; Intelligent Machine Tool Systems; Measurement and Inspection of Products and Processes; Non-Traditional Manufacturing Processes of the 1990s, 1994
Abstract A neural network based compensation strategy for five-axis machine tool error correction has been developed. It is capable of significantly reducing geometric, kinematic and thermal errors between the tool tip and the workpiece.

Development of the integration of postprocessor for five-axis machine tools

2012 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2012
A postprocessor capable of converting the cutter location data to machine control data is the important interface between the NC programming design and the manufacture. Owing to the fact that multi-axis NC data can only be applied to the specified machine tool configuration and various combinations may be synthesized to multi-axis machine tool ...

Planning of tool orientation for five-axis cavity machining

The International Journal of Advanced Manufacturing Technology, 2003
This study examines the feasibility of using open regions and vector fields to determine the appropriate tool orientation in five-axis NC machining of cavity regions with undercut areas. The first step involves slicing the to-be-machined surface into thin layers and then comparing those layers to find the position of the undercut; that is, the position

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 ...

Dynamic Characteristics of Five-Axis CNC Machine Tools

Applied Mechanics and Materials, 2013
According to the five-axis CNC machine tools, the main components are put to flexible and a rigid-flexible virtual prototype has been established. The influence on the machine tool stability is analyzed. The reliable theoretical basis has been provided for the structure optimization.

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.
