Performance appraisal in personnel management has its good effect no matter which industry it is used in. Good performance appraisal indicators play a great role in mobilizing the enthusiasm of the majority of employees, improving production efficiency, and completing production tasks according to the plan. Therefore, rationally formulating performance indicators is the top priority of enterprise management in the machining industry. So, what are the performance appraisal methods for numerical control machine tool processing workers?

　　Every company‘s personnel department will issue some job performance appraisal standards, and the performance appraisal standards of different industries will get good results when applied to the corresponding fields. Of course, the premise is reasonable. Good performance appraisal plays an important role in mobilizing the enthusiasm of the majority of employees, improving work productivity, and completing production tasks according to the plan to ensure quality assurance. Therefore, the reasonable formulation of performance indicators is also a very important part of enterprise management in the machining industry. So, as numerical control processing manufacturers, how can we formulate performance appraisal standards and methods? Shenzhen EMAR Precision Technology Co., Ltd. is a professional manufacturer dedicated to high-quality parts processing. We have taken stock of some numerical control processing performance appraisal methods in the industry. Let‘s take a look. As a numerical control processing manufacturer, you may be able to learn from it.

　　The performance appraisal method of numerical control machine tool processing workers is mainly applicable to all employees engaged in the production of numerical control milling machines in the production department and the car workshop.

　　A method of generating general machining man-hours

　　General machining enterprises are through the production of working hours to carry out performance mangement. The design of working hours mainly uses a combination of three methods: technical measurement, software assistance and empirical analysis.

　　The method of generating machining working hours is mainly composed of machining working hours and auxiliary working hours. The main calculation methods are as follows:

　　Machining man-hours = product theoretical man-hours processing coefficient + auxiliary time

　　In this formula, the auxiliary time mainly refers to the time consumed by the preparation before production, the clamping, tool change and the self-inspection process of employees during processing. The processing coefficient is the difficulty of the product in actual processing, the fatigue of employees, etc. Generally, everyone will use the tentative value 1.08-1. However, for difficult-to-process materials and products with imperfect craftsmanship, the actual processing time of the processing time meeting shall prevail.

　　3. How to generate support working hours

　　The frequency of support hours is not high, but it can also occur under special circumstances. The employee needs to support other departments or positions, and the actual time of attendance is used as his support hours.

　　2. How to generate incentive hours

　　The reward working hours of a product are determined by the completion of the production task of the product and the inspection results of the product. Its calculation formula is:

　　Bonus man-hours = machining time (difficulty coefficient + quality coefficient + 1)

　　4. Calculation method of lost working hours

　　Wasted man-hours are mainly due to waiting time caused by other reasons, increased processing time due to drawing changes, repair time caused by subsequent processing, and unpredictable time caused by non-processing. The actual processing time is machining man-hours and is not included in the wasted man-hours.

　　5. Calculation method of monthly performance hours

　　The performance hours of employees are mainly the sum of the machining company, reward hours, support hours and wasted hours and attendance time during the month. Its calculation formula is:

　　Monthly Performance Hours = Total Machining Hours + Bonus Hours + Wasted Hours + Support Hours - Attendance Hours

　　Through the above sharing, do you have a new idea about the performance appraisal method of your factory? EMAR Precision Technology believes that the performance appraisal system is a double-edged sword. If it is made properly, it can effectively mobilize the enthusiasm and initiative of employees, improve production and processing efficiency, and better complete the production tasks delivered by users. If it is made irrationally, it will make employees feel that it cannot be achieved anyway, so they ignore it. Therefore, we must develop an employee performance appraisal mechanism according to the actual situation of the company.
