The processing of the piece surfaces involves the transformation of the blank into a piece, the defining characteristics of the surfaces (the form, dimensions, deviations, etc.), depending to a large extent on the parameters of the generated processe

Progressive cavity pumps are used in industry for the circulation of high viscosity fluids, such as crude oil and petroleum products, sewage sludge, oils, salt water, and wastewater. Also known as single screw pumps, these pumps are composed of a sin

Situations encountered in “reverse engineering” are relatively common in which, to address a problem of profiling generating tools for processing an orderly curl of surfaces (cylindrical or helical teeth), data known by measuring the existing pro

The conical rotary compressor represents a solution for gases compression, for relatively small flow, in conditions of a superior energetic efficiency. Although the theoretical solution for the helical conical compressor was elaborated decades ago, a

This paper approach the issue of side mill profiling, for generation of helical surfaces – the sealing worms from the construction of the helical pumps with cycloid worms. The issue of side mill profiling is based on the complementary theorem of th

The generation of the ordinate surfaces whirl attached to a centrode (e.g. cylindrical or helical gears teeth generation) with a hob mill is an efficient method, also recommended in machining the teeth of slitting saw cutter with high dimensions. Pro

In this paper, we present, comparatively, two analytical methods for profiling the tools delimited by revolution surfaces, used to generate helical surfaces with constant pitch. The first method lays on a complementary theorem used for tools profilin

A new graphical solution is proposed, for profiling the side mill which generates a cylindrical helical surface with constant pitch. The method uses a specific complementary theorem: the generating trajectories theorem. This is a new express form of
