Calculation of technological cycles of manufacturing model blocks for the lost-wax casting method, taking into account the stability coefficient of the duration processes

Abstract

The paper considers the technological cycles of obtaining wax models in automatic molds, in manual molds and by the additive method. The cyclograms of the work of the site for obtaining model blocks consisting of wax models are shown. The dependences of the duration of time cycles for the considered methods of obtaining wax models are presented. It is revealed that the production of wax models in automatic molds is the most productive method, however, this method has the longest cycle of technological preparation of production. The production of wax models in manual molds has a cycle duration comparable to the previous method of technological preparation of production, however, the cycle duration of obtaining wax models for this method is longer. The additive method makes it possible to produce products with a minimum duration of the pre-production cycle. The main operations of manufacturing wax models by the methods under consideration are revealed. The influence of the stability coefficient of operations on the work organization of the site for production wax models is analyzed.
