When the original accuracy of the machine tool, cutting tool, fixture and workpiece blank etc. all meet the process requirements without considering the dynamic factors, the effect of adjustment error plays a decisive role in machining accuracy. Improve the geometric accuracy of the machine tool used for parts machining

There are many factors that influence welding distortion; in summary, these can be categorised into three main areas: materials, structure and process. Whilst ensuring the structural load-bearing capacity is maintained, weld dimensions should be kept as small as possible to minimise the impact of welding heat input on the material’s properties.
