METHOD FOR MANUFACTURING OBJECTS BY ROTATING WIRE CUTTING METHOD

摘要

It is often required to manufacture rotationally symmetric objects like pillars, balls etc. For soft materials like EPS foam, hotwire bent to required shape can be rotated to achieve desired shape. A machine for manufacturing such objects is proposed, in which workpiece clamping is simplified and multiple objects can be manufactured simultaneously. An automatic clamping method is proposed, which will minimize shape defects at ending point of cut. A method of bending the wire to accurate shapes with appropriate geometric compensation for thermal melting loss is proposed in this invention.
