Contributions to the calculation of norm time edge thinning operations parts of footwear

Abstract

It is known that regulations allow the introduction in production regimes efficient operation of equipment and methods of rational organization of production. To ensure accuracy imposed regulations must meet the following conditions: to take into account the main factors influencing consumption of work; depending on the types of production which they are intended to ensure adequate precision. In this work the analysis literature authors proposed a new relationship for calculating the standard time for the operation of thinning also set the value of two coefficients K1 and K2. K1 is a constant coefficient for thinning operation of 1,0549; and K2 - a constant that depends on the degree of automation of the machine. Knowing the degree of mechanization machines and time required to perform operation coefficient was determined K2, namely Km – 1,0833; KM – 1,0460; KA – 0,0785. Since the relationship for the calculation of the time aids not it into consideration that a part may contain from 3 to 5 types of profiles, it has been proposed that it be included in the relationship, so there was obtained a new relationship calculation. The study conducted also allowed the optimization of computing time assistant relationship, including the number of adjustments in relation computing machine. Proper use of normative values, taking into account the type of machine, but also their knowledge calclulul methodology allow us to identify the following positive effects on the company's footwear: reducing workload; achieving balanced labor standards; saving human effort; reducing worker fatigue etc.
