Vision-based on-machine measurement for CNC machine tool

SPIE Proceedings, 2015
A vision-based on-machine measurement system (OMM) was developed to improve manufacturing effectiveness. It was based on a visual probe to enable the CNC machine tool itself to act as a coordinate measuring machine (CMM) to inspect a workpiece. The proposed OMM system was composed of a visual probe and two software modules: computer-aided inspection ...

Contour Assessment of CNC Machine Tools

1993
The purpose of this paper is to discuss the methods used at AWE Aldermaston to assess the contouring accuracy of computer numerically controlled (CNC) machine tools procured by AWE. It will also explain how the measurement and evaluation techniques have been developed over the years for this purpose.

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 ...

Feedback Interpolators for CNC Machine Tools

Journal of Manufacturing Science and Engineering, 1997
This paper presents interpolators that are capable of generating 2D curves in general implicit forms and 3D curves in general parametric forms. In contrast to the existing interpolators, which utilize complicated algorithms to meet the interpolation requirements such as maintaining high accuracy and constant feedrate, the proposed interpolators utilize

Machining Feature-Driven 5-Axis CNC Machine Tools

2006
With a 5-axis CNC machine tool that is built according to the new CNC data model, a user considers information about only the motion of tools, such as the machining shape, the machining operation, and the cutting condition. The user can work without being influenced by the structure of the machine.

INTERPOLATOR FEATURES FOR CNC SYSTEMS OF MACHINE TOOLS

IFAC Proceedings Volumes, 1980
Abstract Most interpolators used in CNC systems of machine tools are based on the DDA principle. Most of such devices provide linear and circular interpolation with constant path velocity. The use of microprocessors in recent CNC systems has rendered it possible to implement more sophisticated interpolation features, such as modified path generation ...
