The technological processing sequence of the product is a sequence of technologically indivisible (technological) operations, the number of which depends on the type of product, complexity of the model, the number of parts, ways of processing and type of fabric. In the processing of men's winter coats, there are atomic operations to 250, mens winter coats - up to 300, and men's shirts up to 80.
The sequence of processing by individual nodes (e.g., processing on-Board pads, lining, back, and shelves, processing and collection of pockets, etc. with subsequent separation of technologically indivisible transactions) are in the form of a table. 12. For example, the process sequence of the processing side of the jacket (see table. 18).
Indivisible operations (column 1) are divided into three groups:
preparation of cut - validation, pruning cutting and marking parts;
procurement of parts - machining of valves, podborov, lower collar, side strips etc.;
the main process - process shelves (coats, suits, dresses), Trouser halves, the assembling of details and finishing products.
Specialty (column 2) indicate according to the type of equipment on which the operation is performed, and write short machine - M, special machine, Ironing, press - PR, manual - R.
Category of work (column 3) establish the tariff-qualification Handbook.
Operational (piece) time (column 4) record the timing data or the time norms specified in instructional technology maps. Operational time (texp) for work performed on the presses, set based on the number of presses served by one worker.
So, if you are a single press texp = tома - t.R, where tома - exposure time product in the press, (pressing time); tвр - time accessory, handmade, p
If you work on multiple presses texp = TC/KP.t where TC is the period of time during which regularly carried out the same work on all presses one worker; CP.t - number of PR, EDM itow the work.
When serving one work group presses their number is determined by the ratio of time (time compression) and support (time spent performing manual techniques work and transitions from one press to another). When composing technological sequence of processing, it is necessary to make a good use of time (pressing) to perform manual tricks on other presses and transitions from one press to another, i.e. that most of the time was still a subsidiary.
The time for preparatory and final work, maintenance of workplace (column 5) different companies can be different and depends on the technical equipment of the factory. Time for personal needs and rest is taken equal to 2.1% of RAM.
The time (column 6) HBP is a waste of time, calculated per unit of work performed, and is determined by the formula HBP = texp(1 + (K1 + K2)/100), where K1 - maintenance of the workplace and preparatory-final works; K2 - time on personal needs and leisure.
In box 7 indicate the type and class of cars, the manufacturer, type of presses, tools and fixtures for machine, Ironing and manual operations (special paws, guides, rulers, templates, etc.).
After the preparation of the processing sequence calculates the total time of manufacture of the product, summing up all atomic operations, and to determine the specific gravity machine, specmachin, Ironing, pressing and manual works, relative to the total processing time of the product.
To facilitate and expedite the acquisition of the organizational operations appropriate for the development of the technological scheme (division of labour) pre-typologies of atomic operations. This card file consists of cards measuring 10 X 7 cm, which should contain the following parameters: transaction number, name, specialty, category and the time allowed. Card be each technologically indivisible operation, and for various professions establish a specific color card.
Cards should be kept in a special box in order technologically indivisible operations.
Below is the card format.
