The Computation of Rigidity for the Step Parts, Cut on Lathe
Journal Title: RECENT - Year 2009, Vol 10, Issue 26
Abstract
In the classical strategy of the dimensional directing of the machining processes the particular stress is laid upon the machining agent (programmer), while the adaptive management is based on the interpretation of the information collected from the process and machined through the program. For the adaptive control, the knowledge of the possible strains, which the semi-finished product may show (mainly in case of high duty), is essential. In this work, there is proposed an analytical way of computation for the possible strain of the middle fibre of the semi-finished product that is being processed, an objective less discussed in the literature. Thus, there is also met the permanent interest for the improvement of the mathematical models, which become more and more adequate for the description of these machining processes. This tendency is also supported by the occurrence of some more and more performant sensors and subassemblies for pressure, vibrations and temperature measurement.
