1.2. Determining the type of production.
Each machine shop has a list of products and spare parts it needs to produce in a year. This is called a data production program, and it contains enough information about the type, number, size, and material of the data. Based on the general production program of the enterprise, a production program for the shops will be developed. Each product is enriched with a general appearance drawing, working drawing of details, assembly drawing, specifications and technical requirements. , gross. Each type of production has its own organizational form. It should be noted that a single enterprise can have different types of production.
The type of production and the corresponding form of work organization determine the classification of the technological process and its structure. Therefore, determining the type of production is the main basic stage in the design of the technological process of machining a part. Determining the type of production by the tabular method requires the weight of the part and the annual production program. It is made mainly of grey cast iron CCH35-10 GOST 1215-79 in multi-series production conditions, weighing m = 1.8 kg, we accept N = 90000 pieces. ([10], 2j, 18b) we can say that the type of production is medium series.
Based on the given annual program, the production step is calculated using the following expression.
= = 2.68 hour/min
Here: hours - one-year real working time fund of machines; N = 90,000 units - annual production program.
The work schedule of the department is 2 shifts. In serial production, it is necessary to calculate the number of parts in a batch, because the parts are processed in batches.
= = 2125.98 units
Here: a = 3, 6, 12, 24 days - the period of inclusion of batch details in processing; F = 254 days is the number of working days in a year.
