This paper presents a method of general geometrical definitions of screw machine rotors
and their manufacturing tools. It describes the details of lobe shape specification, and …

We propose a new method for 5-axis flank computer numerically controlled (CNC)
machining of screw rotors using conical tools. The flanks of screw rotors consist of helical …

While designing a screw compressor, the design of the rotor profiles is the most important
because rotor profiles essentially determine the overall performance of the screw …

The theory of enveloping, which determines the envelope to a family of surfaces, the
meshing equations of kinematics pairs, including pinion and gear, cutting toll and gear, is …

Compressor is the single largest consumer of primary energy (usually electricity) in an
industrial refrigeration system and often become a focal point for energy efficiency …

In der Vakuumtechnik sind, je nach Anwendung, eine Vielzahl verschiedener
Pumpprinzipien erfolgreich. Das Einsatzgebiet der verschiedenen Pumpen und …

The active surfaces of the screw compressors rotors are cylindrical helicoidal surfaces, with
constant step; these surfaces are complex surfaces in order to meet a set of specifics …

The screw compressor rotors are bounded by cylindrical helical surfaces, with constant
pitch. The generation of these surfaces is possible to be done using disk cutter, whose …

The profiling of tools bounded by revolution surfaces–disc tool, end mill tool and ring tool–is
based on fundamental theorems of the surfaces enwrapping. There are situations when the …
