Selection of Cutting Blades and Improvement of Machining Parameters for Loader Frame Milling Processes

摘要

装载机车架作为整机承载、连接、传力的关键结构部件，它的加工质量会直接对装配精度、运行稳定性还有服役寿命产生影响。车架通常是运用高强度钢板通过焊接而成形的，其结构尺寸较大，焊缝数量较多，并且加工余量不均匀，在铣削过程里容易出现刀片磨损速度较快、崩刃、振动、表面粗糙度不稳定等状况。合理地挑选铣削刀片并且对切削参数进行优化，是提高加工效率、降低刀具成本、保障产品质量的重要方式。本文针对装载机车架铣削加工的刀片选型与切削参数改进进行研究，剖析车架加工特点、刀片失效原因、选型原则、参数优化方法，进而提出工艺改进措施，为工程机械结构件能够实现高效稳定加工提供一定的参考。

Abstract

As a critical structural component responsible for load-bearing, connection, and force transmission in loader frames, the machining quality of this part directly impacts assembly accuracy, operational stability, and service life. Frame structures are typically fabricated from high-strength steel plates through welding, featuring large dimensions, numerous weld joints, and uneven machining allowances. These characteristics often lead to issues such as rapid tool blade wear, edge chipping, vibration, and unstable surface roughness during milling operations. Proper selection of milling cutters and optimization of cutting parameters are essential strategies for improving processing efficiency, reducing tool costs, and ensuring product quality. This study investigates cutter selection and cutting parameter optimization for loader frame milling, analyzes frame machining characteristics, causes of cutter failure, selection principles, and parameter improvement methods, and proposes process enhancement measures to facilitate efficient and stable machining of structural components in construction machinery.
