An algorithm for tool orientation vectors compression on five-axis CNC machining
2011 6th IEEE Conference on Industrial Electronics and Applications, 2011An algorithm for tool orientation vectors compression is proposed in this paper with the aim of shortening size of machining codes and maintaining small feedrate fluctuations in five-axis CNC machining. In this algorithm, tool orientation vectors are firstly segmented according to the inflection of the curve composed of their tips. Secondly, vectors in

Total ballbar dynamic tests for five-axis CNC machine tools
International Journal of Machine Tools and Manufacture, 2009The linear and rotary axes of a five-axis machine tool are driven simultaneously to generate a specified tool position and orientation in workpiece coordinates. It is crucial that these servo-controlled axes are of balanced dynamics to achieve high tracking accuracy.

Pre-compensation of contour errors in five-axis CNC machine tools
International Journal of Machine Tools and Manufacture, 2013Abstract This paper presents an analytical prediction and compensation of contouring errors in five-axis machining of splined tool paths. The position commands are first fitted to piecewise quintic splines while respecting velocity, acceleration and jerk continuity at the spline joints.

Modeling of the Dynamic Contour Error of Five-Axis CNC Machine Tools
Dynamic Systems and Control, 1999Abstract This paper focuses on the dynamic contour errors due to the coordinated five-axis motion. The dynamic contour error for tracking a contour is defined as the difference between the desired contour and the actual responded tool trajectory to the contouring motion command.

Modelling geometric and thermal errors in a five-axis cnc machine tool
International Journal of Machine Tools and Manufacture, 1995Abstract The total volumetric error within the workspace of a machine tool is induced by the propagation of both scalar and position dependent geometrical errors, as well as time-variant thermal errors. This paper presents a compact volumetric error model which can be used as a basis for a practical compensation scheme.

A novel kinematic model for five-axis machine tools and its CNC applications
The International Journal of Advanced Manufacturing Technology, 2012In conventional five-axis CNC machining, the machine structure is treated as a single kinematic chain just like a robotic manipulator while the cutter is treated as an end effector. In this paper, besides the machine kinematic chain, a cutter kinematic chain is introduced, and the two subkinematic chains are combined to form one machine–cutter ...
