板材试样变形原因及改进措施

Causes for Plate Specimen Deformation and Improvement Measures

在机械加工中常发现试样有不同程度变形,主要有瓢曲与扭转变形,严重影响试样加工精度,影响试样物理性能的准确性。对宽带试样变形的产生原因及试样变形对机械加工的影响进行研究分析,并采取相应措施,保证了加工质量,提高了加工效率。

In machining, samples are often found to be deformed in varying degrees, mainly bulges anti twisting strain,which seriously impact on sample processing accuracy and the accuracy of sample physical properties. The causes for wide strip specimen deformation and its impact On mechanical processing were analyzed and studied, based on which corresponding measures were adopted to ensure processing quality, thus improving processing efficiency.
