Journal ArticleDOI
A parametric interpolator with confined chord errors, acceleration and deceleration for NC machining
Tsehaw Yong,Ranga Narayanaswami +1 more
TL;DR: Simulation results indicate that the offline detection of feed rate sensitive corners improves parametric interpolation.
Journal ArticleDOI
Tool wear monitoring in ramp cuts in end milling using the wavelet transform
TL;DR: In this article, the root mean square (RMS) value of the wavelet transformed signal and linear regression are used for tool wear estimation, which is also estimated by measuring the resulting slot thickness on a coordinate measuring machine.
Journal ArticleDOI
Multiresolution analysis as an approach for tool path planning in NC machining
Ranga Narayanaswami,Junhua Pang +1 more
TL;DR: Experimental results indicate that wavelet-based tool path planning improves machining efficiency and the applicability of multiresolution analysis using B-spline wavelets to NC machining of contoured 2D objects is investigated.
Journal ArticleDOI
Multiresolution modeling techniques in CAD
Ranga Narayanaswami,Ji Yan +1 more
TL;DR: In this paper, wavelet-based multiresolution modeling techniques in CAD models in the system are represented by endpoint-interpolating B-spline functions Wavelet deformation techniques are extended to include synthesis editing and detail blending from previous sweep editing and fractional editing methods.
Journal ArticleDOI
Multiresolution offsetting and loose convex hull clipping for 2.5D NC machining
Junhua Pang,Ranga Narayanaswami +1 more
TL;DR: B-spline wavelet theory is applied to NC machining of contoured 2D objects and simulation results indicate that the wavelet based tool paths and clipping improves machining efficiency.
