Evaluation of the Dynamic Performance for Five-Axis CNC Machine Tools Based on RTCP
Volume 14: Emerging Technologies; Safety Engineering and Risk Analysis; Materials: Genetics to Structures, 2015RTCP (rotation tool center point), which is one of the necessary functions for high-grade CNC machine tools, can effectively decrease nonlinear errors caused by the motion of the rotation axis and improve the accuracy of the machinery. Based on the characteristic that the cutting tool tip point is relative to the manufacturing workpiece, the RTCP ...

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 ...

Bevel Gear Cutting Using a Disk Tool on a CNC Five-Axis Machine
2017Considering flexible manufacturing of large gears in small and medium batch productions, a five-axis CNC machine is a good choice because it is cheaper and easier to be obtained compared to a dedicated bevel gear cutting machine. Company Heller recently released a new cutting method for bevel gears on its five-axis machines.

Ballbar dynamic tests for rotary axes of five-axis CNC machine tools
International Journal of Machine Tools and Manufacture, 2014Abstract This paper proposes a new ball bar test method for the inspection of dynamic errors of rotary axes in five-axis CNC machine tools. The test circle is defined in a workpiece coordinate system and the ball bar test is performed by simultaneously driving of linear–rotary axis couple.

The optimal feedrate planning on five-axis parametric tool path with multi-constraints remains challenging due to the variable curvature of tool path curves and the nonlinear relationships between the Cartesian space and joint space. The methods for solving this problem are very limited at present. The optimal feedrate associated with a programmed tool

A generalized on-line estimation and control of five-axis contouring errors of CNC machine tools
International Journal of Machine Tools and Manufacture, 2015Nonlinear and configuration-dependent five-axis kinematics make contouring errors difficult to estimate and control in real time. This paper proposes a generalized method for the on-line estimation and control of five-axis contouring errors. First, a generalized Jacobian function is derived based on screw theory in order to synchronize the motions of ...
