Workspace digitization for five-axis machining

2017 International Conference on Applied System Innovation (ICASI), 2017
While performing five-axis machining, it is usually expected to complete all the cutting without having to re-clamp the workpiece. In other words, the workpiece should remain at the same location during the whole five-axis machining process. The current procedure to perform five-axis machining on a workpiece is to use CAM software to generate the tool ...

Machinability analysis and setup optimization for five-axis machining

2016 International Conference on Applied System Innovation (ICASI), 2016
Two potential problems are usually ignored by CAM software for five-axis machining: one is the overtravel for the three linear axes of the five-axis machine tool, and the other is the collision between the spindle and the worktable. The objective of this research was to propose a method based on the visibility map and then, develop a computer program ...

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 ...

CAD/CAM for Five-Axis Printing Machine

Key Engineering Materials, 2011
In this study, CAD/CAM system for a 5-axis printing machine was developed. The configuration of 5-axis printing machine is based on the 5-axis CNC milling machine; the spindle of the 5-axis CNC milling machine was replaced by a commercial printer. CAD software was first used to develop a three dimensional model, after that a color figure which will be ...

Teaching Four and Five-Axis CNC Machining

Innovations in Engineering Education: Mechanical Engineering Education, Mechanical Engineering/Mechanical Engineering Technology Department Heads, 2004
Traditional metal-based manufacturing processes are being driven to multi-axis machining. Manufacturing time studies have proven that there are significant cycle time reductions using multi-axis CNC machining as compared to multi-fixture CNC machining. Four and five-axis machining requires the use of software to produce both required part geometry and ...

Five-Axis NC Machining of Sculptured Surfaces

The International Journal of Advanced Manufacturing Technology, 1999
This paper presents a new method for the determination of tool position and orientation for NC milling of sculptured surfaces with a five-axis NC machine. This method uses an analysis of local curvatures of the surface and the tool geometry. Based on matching these local properties, optimal tool axis orientations are selected so that the gouging error ...

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.

Five-axis machining time estimation algorithm based on machine characteristics

Journal of Materials Processing Technology, 2007
Abstract In this paper, we present a machining time estimation algorithm for five-axis high-speed machining. Estimation of machining time plays an important role in process planning and production scheduling of a shop. In contrast to the rapid evolution of machine tools and controllers, machining time calculation is still based on simple algorithms ...

Machine models and tool motions for simulating five-axis machining

Computer-Aided Design, 2010
This paper presents a method of determining the tool motion of a five-axis machine. The method is motivated by the imprint point method, where points on the machined surface are computed based on the tool position and tool motion. While simple linear motion can be used as a coarse approximation to this motion, this paper looks at more accurate models ...
