How to calculate the production capacity of a mechanical processing plant

Production capacity (capacity) is an important issue for all enterprises and all levels of enterprises. Production capacity refers to the maximum that a work unit can handle at full capacity. The operation unit here can be a factory, department, machine or a single worker.


In this type of enterprise, the organization of the production department adopts the principle of process specialization, and the product input and output have a long interval and obvious periodicity. Their production capacity calculations are closely related to the division of workshops and teams on the principle of process specialization.

1. Calculate the production capacity of batch processing enterprises

(1) Calculate the capacity of a single device

Since the processed parts are not a single species, the number can reach hundreds of thousands. The shape and size of all parts are different, the processing steps are also different, and the processing time is different. At this time, the output cannot be calculated, but the effective processing time provided by the equipment can only be used for calculation, which is called machine time.

(2) Calculate the capacity of the team

The workshop team is the smallest production unit. Each team is equipped with a certain number of equipment with the same processing technology, but their performance and capabilities are not necessarily the same. Therefore, the production capacity of the calculation team starts with a single device, and then the production capacity of these devices is integrated and calculated.

If the processing technical parameters of all the equipment in the team are not very different, the sum of the time of all the equipment is the production capacity of the team. If the technical parameters are very different, the machine time of the equipment with different parameters should be counted separately, and the equipment processing capacity of certain large workpieces should be checked whether the equipment processing capacity can meet the production requirements.

(3) Determine workshop capacity

Since the processing objects of the team are parts, their capabilities should be measured by machine hours, and for the workshop its production objects are often the number of products or parts, so its production capacity should be measured by output. The conversion between working hours and output is relatively simple.

(4) Determine factory capacity

The production capacity of the factory can be determined according to the capacity of the main production workshop, and workshops with insufficient capacity can be solved by adjustment measures.

2. Calculating the production capacity of pipeline enterprises

(1) Calculate the production capacity of the assembly line

The production capacity of the assembly line depends on the production capacity of each process equipment, so the calculation starts from a single piece of equipment.


The calculation formula is as follows: M order=He/ti, where: M order——single equipment production capacity; He——single equipment planning period (year) effective working time (hours); ti——single product in this The time quota for processing on the equipment (hours/piece).

If the process is undertaken by a piece of equipment, the production capacity of a single piece of equipment is the process capability. When the process is undertaken by N equipment, the process production capacity is M orders×N.

(2) Determine the production capacity of the workshop

If it is a manufacturing workshop, it has both parts processing lines and component assembly lines. At this time, its production capacity should be determined by the ability of the assembly line. Even if the processing capacity of individual parts is lower than the assembly line capacity, it should be determined according to this principle.

If it is a parts processing workshop, each part has a dedicated production line, and all parts are matched with the company's products, then the production capacity of the workshop should depend on the capacity of the production line with the smallest production capacity.

(3) Determine the production capacity of the enterprise

Due to the large differences in the processing objects and processing techniques between the various workshops, the performance of the equipment selected is very different, and the production capacity is inconsistent. Therefore, the production capacity of the basic production workshop is usually determined by the dominant production link. When the production capacity of the basic production workshop and the auxiliary production department are inconsistent, the enterprise should be determined by the production capacity of the basic production workshop.
