How to make machining hours of CNC machining center?

For machining enterprises, in order to meet the needs of product expansion of the company, it is necessary to refine and revise the man hour quota of the CNC machining center according to the existing production situation of the company, the company’s experience for many years, and the production process and characteristics of different models. Next, we will specifically introduce how to formulate the machining hours of the CNC machining center.

1. The significance of working hours in NC Machining Center

Considering the current technical level and management level of the enterprise, improve the operation conditions and improve the operation efficiency to reach the advanced and reasonable working hour quota level, and provide scientific basis for the production organization and operation management of the enterprise.

2. Calculation of machining hours of CNC machining center

In order to make the formulation of man hour quota more advanced, reasonable, standardized and scientific, and provide a basic data platform for operation and management, the technical center, the personnel and labor department, the planning and finance department and other relevant departments have been organized to revise the man hour, and a man hour calculation project team has been established:

 (1) Relevant departments shall discuss and determine the standards based on the current situation and previous experience of the enterprise;

 (2) Summarize the discussion results and formulate the statistical table of man hour quota;

 (3) The processing technology of some special processing parts is sorted out and summarized as a reference for the formulation of processing hours.

 (4) Adjust the staffing, and reduce the professional staffing for some simple operations.

 (5) The original man hour and the revised man hour are compared according to each discipline, and the situation is summarized.

3. Problems in the process of making NC machining man hours

 (1) The man hour quota standards formulated by different models are not uniform, which makes it impossible to measure the processing man hour and fails to reflect the rationality of the man hour quota.

 (2) The basis for working hours of the same discipline in each workshop is not uniform, which fails to reflect the principle of equal pay for equal work.

 (3) Some models have been revised for many years and tend to be advanced and reasonable, while the standards for the newly put into production models are relatively loose in the formulation of processing hours.

4. Methods and steps for making NC machining hours

 (1) When working out the working hours of CNC machining center, it is necessary to formulate the working hours quota standard in combination with the actual process level and industry level.

 (2) Fine analysis of the company’s quota standards, further subdivide the processing procedures, and ensure the enforceability of the working hours.

 (3) After the first two steps are completed, the statistical table of man hour quota of CNC machining center is completed.

 (4) Carry out the revision step by step according to the statistical table of working hour quota.

 (5) Determine the working hour quota standard and organize relevant personnel to finalize it.

 (6) After the revised model is officially released, the man hour quota of other models will be standardized based on this standard.
