The traditional method of wood mold manufacturing is to determine the model classification and module structure according to the casting process drawing of the parts, draw the lofting drawing by hand, and make and assemble the blocks. Among them, lofting is the specification of two-dimensional drawing size of parts, which is also the standard of module manufacturing. At the same time, it is also a key process of model design and manufacturing, which requires high technical level of mold makers. For some complex parts, in the process of mold manufacturing, due to the two-dimensional drawing size is not perfect and the mold maker's understanding of the drawing is not thorough and other problems, the mold inevitably has the problem of inaccurate size. Most of these problems can only be verified gradually in the process of model manufacturing, and some can only be found after the casting is manufactured. This not only increases the workload of mold development, delays the progress of new product development, but also has problems such as low mold accuracy.
 
In five axis machining, the use of flat end milling cutter can greatly reduce the processing time by keeping the complex mold surface vertical. The principle of five axis machining center is also applicable to the side milling with angle surface, which can eliminate the rib like grain caused by the ball end milling cutter, make the surface quality of the mold more ideal, and reduce the workload of manual milling and manual operation due to cleaning the mold surface.
 
Through the five axis machining technology, the problem that the workpiece needs to be debugged and clamped for many times in the complex angle positioning can be solved, which not only shortens the time, but also greatly reduces the error, and saves the large cost of the fixture when installing the workpiece, and the machine tool also achieves the processing of complex parts, such as the drilling of complex surface The traditional methods can't do it.      
 
The tool used in five axis machining is short, and the whole part can be processed at one time. There is no need to install the card again or use the longer tool needed in the same kind of three-axis machining, which can complete the mold production in a short time, and the surface quality of the parts is also better.
 
The application of RECOJY five axis machining center saves the labor cost and shortens the development cycle of the mold. Moreover, it can process high-precision curved surface, make high-precision model, and then produce high-precision castings. With the rise of labor costs and the improvement of accuracy requirements of wood mold, the application of five axis machining center to make wood mold will become the development trend of casting mold industry.
