Surface burn during grinding processes is a thermally induced damage creating unwanted changes and must be avoided. Previous studies correlated surface burn with a critical temperature as its threshold. In this study, metal oxidation at high temperatures is proposed as the mechanism responsible for burn, and a model is developed considering both temperature and exposure time to predict the occurrence of burn and its thickness. Grinding tests were carried out and the cross-sections of the samples were analyzed to validate the model. The model use was demonstrated satisfactorily for selection of burn free and high productivity grinding conditions.

磨削过程中表面烧伤及其厚度的预测

磨削过程中的表面烧伤是由热引起的损坏，会产生不必要的变化，必须避免。以前的研究将表面烧伤与临界温度作为阈值相关联。在这项研究中，高温下的金属氧化被认为是造成烧伤的机制，并开发了一个同时考虑温度和暴露时间的模型来预测烧伤的发生及其厚度。进行了磨削试验并分析了样品的横截面以验证模型。该模型的使用在选择无烧伤和高生产率研磨条件方面得到了令人满意的证明。
