This paper aims to review the challenges of performance appraisal in organizations and argue that these challenges can and must be overcome.

The authors review research on performance appraisal in organizations and on claims that organizations are abandoning performance appraisal.

Structured performance appraisals are still the norm in organizations around the world. There are clear and practical strategies for improving appraisals. These include improving feedback and removing unnecessary complexity, clarifying the goals of appraisal systems, focusing appraisal on behaviors and outcomes under the employee's control and increasing the fairness of appraisal systems.

Research is needed on the effects of changing the ways performance appraisals are conducted in organizations.

Practical strategies for improving performance appraisal are outlined.

Better performance appraisals will benefit organizations and their members.

This paper refutes the growing claim that organizations are abandoning performance appraisal and illustrates practical strategies for improving performance appraisal.

As an advanced manufacturing method, additive manufacturing (AM) technology provides new possibilities for efficient production and design of parts. However, with the continuous expansion of the application of AM materials, subtractive processing has become one of the necessary steps to improve the accuracy and performance of parts. In this paper, the processing process of AM materials is discussed in depth, and the surface integrity problem caused by it is discussed.

Firstly, we listed and analyzed the characterization parameters of metal surface integrity and its influence on the performance of parts and then introduced the application of integrated processing of metal adding and subtracting materials and the influence of different processing forms on the surface integrity of parts. The surface of the trial-cut material is detected and analyzed, and the surface of the integrated processing of adding and subtracting materials is compared with that of the pure processing of reducing materials, so that the corresponding conclusions are obtained.

In this process, we also found some surface integrity problems, such as knife marks, residual stress and thermal effects. These problems may have a potential negative impact on the performance of the final parts. In processing, we can try to use other integrated processing technologies of adding and subtracting materials, try to combine various integrated processing technologies of adding and subtracting materials, or consider exploring more efficient AM technology to improve processing efficiency. We can also consider adopting production process optimization measures to reduce the processing cost of adding and subtracting materials.

With the gradual improvement of the requirements for the surface quality of parts in the production process and the in-depth implementation of sustainable manufacturing, the demand for integrated processing of metal addition and subtraction materials is likely to continue to grow in the future. By deeply understanding and studying the problems of material reduction and surface integrity of AM materials, we can better meet the challenges in the manufacturing process and improve the quality and performance of parts. This research is very important for promoting the development of manufacturing technology and achieving success in practical application.
