Five-Axis CNC Processing Technology to Form Expendable Patterns

During the casting of expendable pattern complex parts, the pattern accuracy is the key in determining the quality of expendable pattern. The paper conducts research on 5-axis CNC processing technology of multiple axes rotary spindle head expendable pattern, which is applied in processing experiments of complex parts expendable pattern. The results show that it is feasible to directly process expendable pattern with 5-axis CNC machine technology, which will have good promotional value.
