Algorithm of Contour Contour Contour of Complex Surface in NC Machining

Surface Pressure Contour Prediction Using a GRNN Algorithm

A new approach based on a Generalized Regression Neural Network (GRNN) has been proposed to predict the planform surface pressure field on a wing-tail combination in low subsonic flow. Extensive wind tunnel results were used for training the network and verification of the values predicted by this approach. GRNN has been trained by the aforementioned experimental data and subsequently was used ...

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...

Contour Tone Licensing and Contour Tone Representation

In this paper, I argue that the positional restrictions of contour tones do not result from their bimoraicity requirement for licensing. The arguments come from the licensing advantage of syllables in positions that are not moraically privileged, the extra levels of markedness distinction in contour tones that go beyond the maximum mora count allowed in the theory, the differences among contour...

Optimal contour orientations for machining of free{form surfaces

In contour machining of free{form surfaces with a ball{end cutter, the tool contacts the surface along loci that correspond to sections by a set of parallel planes, with equidistant spacing and common normal N. For a given tool radius, the greatest scallop height between successive tool paths is suppressed by choosing an orientation for the contouring planes that will maximize, over the entire ...
