Prediction and compensation of machining geometric errors of five-axis machining centers with kinematic errors [PDF]

Precision Engineering, 2009
Kinematic errors due to geometric inaccuracies in five-axis machining centers cause deviations in tool positions and orientation from commanded values, which consequently affect geometric accuracy of the machined surface. As is well known in the machine tool industry, machining of a cone frustum as specified in NAS979 standard is a widely accepted ...

Simultaneous Five-axis Motion for Identifying Geometric Deviations Through Simulation in Machining Centers with a Double Pivot Head

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
In this paper, simultaneous five-axis control motions were newly proposed to identify the ten inherent deviations to double pivot head type five-axis machines. This motion was designed for the application of a ball bar to the measurements.

Evaluation of dynamic behavior of rotary axis in five-axis machining center (Behavior around motion direction changes)

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
Several methods of evaluating the motion accuracy of the rotary axes of five-axis machining centers have been proposed in past studies. Because it is known that particular motion errors exist near motion direction changing points, it is important to ...

Sensitivity Analysis in Ball Bar Measurement of Three-Dimensional Circular Movement Equivalent to Cone-Frustum Cutting in Five-Axis Machining Centers

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013
The present paper describes the sensitivity coefficient of measurement in the three-dimensional circular interpolation movement that is equivalent to cone-frustum cutting in five-axis machining centers with a tilting rotary table. The sensitive direction

A Comparison Study on the Orientation Capability and Parasitic Motions of Two Novel Articulated Tool Heads with Parallel Kinematics

Advances in Mechanical Engineering, 2013
This paper proposes two novel articulated tool heads based on three degree-of-freedom (DoF) parallel kinematic mechanisms (PKMs). They can realize one translation and the A/B-axis (rotations about the x - and y -axes) linkage movements.

Tool path design for cube-machining test to minimize influence of Z-axis reversal error motion

Journal of Advanced Mechanical Design, Systems, and Manufacturing
Cube-machining test is a possible method for evaluating the accuracy of five-axis machining centers. Although the geometric errors of rotary axes can be evaluated by measuring the height and inclination errors of the machined surfaces, other error ...
