摘要

Medical alloy materials play a crucial role in the manufacturing of medical devices and implants due to their unique physical, chemical, and biocompatible properties. However, the requirements for workpiece quality, surface accuracy, and surface integrity of different medical alloy materials used in different medical departments vary greatly. Therefore, it is particularly important to select appropriate cutting and grinding parameters for processing different medical alloy materials based on their specific characteristics, such as strength, hardness, and toughness. However, there is currently a lack of review on the cutting and grinding mechanisms and processing properties of alloy materials used in various departments to guide the processing and production of medical alloy materials. Based on this, this article first summarizes the properties of commonly used alloy materials, such as magnesium alloys, titanium alloys, and nickel-titanium alloys, in the cutting and grinding processes of various departments including orthopedics, stomatology, cardiovascular surgery, and cardiothoracic surgery. Secondly, this article compares and analyzes the effects of cutting speed, feed rate, cutting depth, and other parameters on surface roughness, cutting and grinding force, cutting and grinding temperature, and residual stress of different alloys during processing. This article summarizes the optimal cutting parameter range for medical alloys. Additionally, this study analyzes the effects of different tool materials and geometric angles on machining performance, and provides suggestions for optimizing tool selection and machining parameters. Finally, the article summarizes key findings on medical alloy machining performance and outlines future research priorities. This study aims to provide theoretical guidance and technical support for the application of medical alloy materials in the field of biomedical engineering.
