The forming of thin-walled parts by laser cladding results in creation of uneven cladding layers that manifests itself in poor surface. Furthermore, it makes follow-up forming difficult. In this case, it becomes necessary to conduct auxiliary mechanical milling and polishing. However, laser forming is one quench solidification process that results in high hardness which makes machining of these hardened surfaces impractical. In addition, if the shape of parts is complex, the finishing machining operations will require multiple jigs and fixture setups which are time consuming and highly inefficient. In fact, the finishing machining operations can account for more than 60% of the entire manufacturing cycle. To overcome the difficulty, a new composite precision rapid prototyping method is proposed. This new method is based on machining the cladding part by laser milling. The proposed high performance and precise approach results in greatly improved surface quality, as measured by surface morphology, as opposed to the traditional laser cladding forming. Furthermore, it will eliminate the need for the post processing and reduce the processing time and ultimately the processing cost of the part.
