Contributions at the Modeling Dimensions of the Gauges by the Wear of this and by the Number of Verified Pieces
Journal Title: RECENT - Year 2013, Vol 14, Issue 40
Abstract
Based on the information’s about the values of the constructive parameters and of the tolerance fields provided by the actual projection standards of the gauges for the control of the cylindrical revolution pieces, both exterior and interior, in the paper it is presented the most adequate mathematical models for the constructive and technological parameters which interfere with the active dimension calculation of the gauges, as well as the method of how it can be optimized the projection methodology by taking in consideration the production batch and the prescribed tolerance field, till the gauge must be replaced. Furthermore, it is presented the adequate mathematical models of admissible wear field depend on the constructive parameters of the gauge and the verified piece.
