摘要 |
A CNC tool grinding machine has at least one rotatable grinding wheel (<HIL><PDAT>1</BOLD><PDAT>) movable relative to a workpiece (<HIL><PDAT>2</BOLD><PDAT>) for grinding a flute surface (<HIL><PDAT>3</BOLD><PDAT>) of a blade in the workpiece (<HIL><PDAT>2</BOLD><PDAT>). The machine is programmed with a path for the grinding wheel (<HIL><PDAT>1</BOLD><PDAT>) calculated to grind a smooth cutting edge (<HIL><PDAT>5</BOLD><PDAT>) for the blade, and programmed with perturbations to the path which vary the movement of the grinding wheel (<HIL><PDAT>1</BOLD><PDAT>) to grind a wavy cutting edge (<HIL><PDAT>6</BOLD><PDAT>) in the workpiece. With such a machine, it is possible to grind all surfaces of a wavy cutting edge in a single set up rather than requiring two more grinding and milling operations to form the wavy cutting edge.</PTEXT> |
