A New 3D Scanning-aided Procedure in Cutting Tool Production

Due to the growing demands on quality in modern production process, it is necessary to design a tool, which will precisely remove the burr off the castings. The burr represents a rough edge or area remaining on material, such as metal, after it has been cast. A tool is able to remove the burr all around the edge and not only in the areas of accumulated material that has been squeezed out (e.g. places where the material is being poured into the mould). A new process of tool design by using 3D scanning-aided technology has been invented by using rapid prototyping principles. The main demands of designing process is getting the precise position of 3D burr line from a real casting that differs from the CAD model due to material shrinking during cooling. Previously used procedures were inadequate and didn’ t meet the quality standards while the new principles in designing of tools significantly improve the efficiency of production.
