为了避免数控折弯机加工板材工件时的表面压痕发生，实验中从板材工件的折弯方式、材料硬度、凹模结构、选择机床与模具的精度4个方面来分析板材工件折弯时的产生表面压痕的原因。结果表明，通过使用防压痕胶垫、单V凹模防压痕胶套、块状优力胶+AT垫衬、硬质橡胶凹模和无压痕折弯凹模的方法来解决数控折弯时工件表面的压痕，达到产品质量要求。

In order avoid numerical control plate bending machining workpiece surface indentation occur,from the plate workpiece bending mode in the experinents,the material hardness,die structre,choose the accuracy of machine tool and mould four aspects to analyze the plate when the workpiece bending of the causes of surface indentation.Results show that by using indentation proof rubber pad,single V die indentation slab,block optimal force glue+AT pad,hard rubber die,and without indentation proof bending die CNC bending when indentation on the surface of the workpiece,to meet the quality requirements.
