Contour-parallel offset machining without tool-retractions

Contour-parallel offset (CPO) machining uses successive offsets of the boundary curves of the machining region as the tool-path-elements (TPEs). For the efficiency of the CPO machining, it is very important to minimize the number of tool-retractions, which cause additional tool movements and do not contribute to the actual cutting. Presented in the paper is a CPO tool-path linking algorithm, wh...

Incomplete mesh offset for NC machining

In this paper, the incomplete triangular mesh including reversed faces and gaps between boundary edges is directly offset for NC machining. or three-axis machining, vertical faces are deleted and the face normal vectors directing the lower part of model are changed to upward. The omplete mesh is offset by the multiple normal vectors of a vertex, and boundary edges and boundary vertices are offs...

A Phase-Offset Estimation Method for InSAR DEM Generation Based on Phase-Offset Functions

This paper presents a novel method for estimating the absolute phase offset in interferometric synthetic aperture radar (SAR) measurements for digital elevation model (DEM) generation. The method is based on “phase-offset functions (POF),” relating phase offset to topographic height, and are computed for two different overlapping interferometric data acquisitions performed with considerably dif...

Adaptive Control of Machining Process Using Electrical Discharging Method (EDM) Based on Self-Tuning Regulator (STR)

In order to improve the optimal performance of a machining process, a booster to improve the serve control system performance with high stability for EDM is needed. According to precise movement of machining process using electrical discharge (EMD), adaptive control is proposed as a major option for accuracy and performance improvement. This article is done to design adaptive controller based o...
