The basis for the compilation of the process sequence processing is the choice of methods of processing on individual nodes. Methods processing choose based on the requirements of normative-technicaldocumentation, sample treatment methods taking into account advanced technology, equipment and small tools.
The basis for selection those or other methods of treatment is the reduction in their use the turnaround time for the processing node of the product T, %, and increased productivity a pile of RP.t, %:
where TD is the processing time of the node on the existing plant, (min); TPR is the processing time of a node on the projected plant (min).
The reduction in time is most often achieved by replacing manual operations machine.
Technological characteristics used in the design process equipment (machines and presses) are on forms 1 and 2.
The technological processing sequence of items of mass manufacturing is in form 3, and products manufactured at the individual orders - in the form 4.
The list of operations prepared for technological operations, i.e. such transactions, which have completed the cycle of works of the same specialty and shall not be division into smaller operations or division which is impractical (for example, the operation "production of two arms").
The sequence treatment be recommended on the basis of existing standards, systematically reviewed under the direction of the Central Bureau of industrial standards for labor (CBPT).
Type of work is determined by the hardware that performs the surgery. Machine the operation is denoted by the letter M, hand P, Ironing - U.
the Category of work set at the tariff-qualifying directory of works and professions of workers of garment industry.
In the final row of the process sequence summarize data counts a standard time for the operation (see form 3) and column Norm time based on percent frequency of occurrence (see form 4) and get the timethe processing of the product (complexity of products). In addition, for enterprises, manufacturing clothing for individual orders, it will be the average time for processing of the product source of at complicating items and finishing work.
