3D circular interpolation motion equivalent to cone-frustum cutting in five-axis machining centers and its sensitivity analysis
نویسندگان
چکیده
The present paper describes a testing method for five-axis machining centers using three-dimensional circular interpolation movement equivalent to cone-frustum cutting. In the present paper, the test conditions, such as the half apex angle of cone-frustum and the sensitive directions of the ball bar device were investigated. In addition, the sensitivity coefficient of each axis was investigated. It is found from the analysis of the sensitivity coefficient that the trajectory due to the errors of the axis of rotation is strongly affected by the sensitive direction of the ball bar for the case of a half apex angle of 45°. © 2012 Published by Elsevier BV.

Design, Manufacturing and Surface quality Analysis of Machining by Self-Rotary Milling Tool
One of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. As a result, the tool would be worn and its life time would be reduced. Therefore, in long time machining, it is essential to change inserts and tools, continiously. A milling tool with self rotary cutting inserts was designed and manufactured that enables i...

متن کامل3D-Orientation Signatures with Conic Kernel Filtering for Multiple Motion Analysis
In this paper we propose a new 3D kernel for the recovery of 3Dorientation signatures. The kernel is a Gaussian function defined in local spherical coordinates and its Cartesian support has the shape of a truncated cone with axis in radial direction and very small angular support. A set of such kernels is obtained by uniformly sampling the 2D space of polar and azimuth angles. The projection of...
