Rotary Contact Method for 5-Axis Tool Positioning

Journal of Manufacturing Science and Engineering, 2012
In this paper, a new 5-axis tool positioning algorithm called the rotary contact method (RCM) for open concave surface machining using the toroidal cutter is developed. The RCM comes from the reverse thinking of multipoint machining (MPM) method and apparently distinguishes the traditional tool positioning principles, as it determines the optimal tool ...

Calibration of rotary joints in multi-axis machine tools

SPIE Proceedings, 2009
A novel technique is developed and implemented for error quantification in a rotary joint of a multi-axis machine tool by using a calibrated double ball bar (DBB) system as a working standard. This technique greatly simplified the measurement setup requirement and accelerated the calibration of rotary joints.

Influence of rotary axis on tool-workpiece loop compliance for five-axis machine tools

Precision Engineering, 2017
Abstract This study investigated the influence of the rotary axis of a 5-axis machine tool on the tool-workpiece compliance. The evaluation focused on the influence of the rotation angle and clamping condition of the B axis on the compliance variation.

Reconstruction of rotary DSA vessel axis based on the matching of multiple projections

SPIE Proceedings, 2005
A novel method of the matching and reconstruction of DSA vessel axis is proposed based on the redundant information from multiple two-dimensional (2-D) projections of the object. First, a correlation scheme on pixels gray level is used to extract the vessel structure on every projection. Through this way, we acquire a binary image.

[Axis registration and image interpolation of rotary scanning echocardiogram].

Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2011
The object of this study was to work at accurate axis registration and interpolation methods for multi-dimension reconstruction of rotary scanning ultrasonic medical images. At first, time-field curves of the images' axes were analyzed according to their characteristic points and the axial direction registration was realized. Similar matrix was used to
