模具钢材的制造过程也是确保模具钢材质量的重要一环，模具钢材制造过程中的加工方法和加工精度也会影响到模具钢材的使用寿命。各零部件的精度直接影响到模具钢材整体装配情况，除掉设备自身精度的影响外，则需通过改善零件的加工方法，提高钳工在模具钢材磨配过程中的技术水平，来提高模具钢材零件的加工精度；若模具钢材整体装配效果达不到要求，则会在试模中让模具钢材在不正常状态下动作的几率提高，对模具钢材的总体质量将会有很大影响。
Die steel manufacturing process is also an important link to ensure the quality of mould steel, mould steel machining method and machining precision in the process of manufacture will affect the service life of the die steel. Directly affect the precision of parts of the whole assembly mould steel, get rid of the influence of accuracy with the device itself, through the improvement of the processing method of parts is needed, improve the fitter in the process of die steel mill with the technical level, to improve the machining precision of die steel parts; If die steel can not meet the requirements, effect on the general assembly will make in the test of die steel in the condition of abnormal action rate has been increased, the overall quality of mould steel will have a great impact.
因此，为保证模具钢材具有良好的原始精度—原始的模具钢材质量，在制造过程中首先要合理选择高精度的加工方法，如电火花、线切割、数控加工等等，同时应注意模具钢材的精度检查，包括模具钢材零件的加工精度、装配精度及通过试模验收工作综合检查模具钢材的精度，在检查时还需尽量选用高精度的测量仪器，对于那些成形表面曲面结构复杂的模具钢材零件，若用普通的直尺、游标卡就无法达到精确的测量数据，这时就需选用三坐标测量仪之类的精密测量设备，来确保测量数据的准确性。
Therefore, in order to ensure the mould steel with good precision of the original - the original die steel quality, first of all, reasonable choice in the process of manufacturing high precision machining method, such as edm, line cutting, CNC machining, etc., at the same time should pay attention to mold steel precision inspection, including the machining precision of die steel parts, assembly accuracy and through the test mould acceptance work comprehensive check the accuracy of die steel, the inspection also need to choose high precision measuring instruments, as far as possible for the forming surface of complex curved surface structure of die steel parts, if use ordinary ruler, vernier card will not be able to achieve accurate measurement data, then we have to choose three coordinates measuring instrument such as precision measuring equipment, to ensure the accuracy of the measurement data.
