Abstract
There is provided a roll surface machining method and apparatus for using a cutting tool to carry out ultra-precision machining in the surface of a roll with a reduced amount of data. The apparatus and method for roll surface machining includes setting a machining start position of a cutting tool with respect to the surface of the roll by C-axis indexing of the roll and positioning of the roll in the axial direction (Z-axis direction) both with respect to the cutting tool. Also the cutting tool and the roll are moved relative to each other in the axial direction of the roll by position control using C-Z axis interpolation, thereby forming a three-dimensional pattern in the surface of the roll.

A roll surface machining method for forming a three-dimensional pattern of protrusions or recesses in a helical arrangement at a predetermined lead angle in the surface of a roll by using a NC roll turning lathe provided with an indexing axis (C-axis) and Z-axis for controlling a position of a cutting tool in the axial direction, and a C-Z axis interpolation means, said method comprising the steps of:
- setting a machining start position of the cutting tool with respect to the surface of the roll by C-axis indexing of the roll and positioning of the roll in the axial direction (Z-axis direction) both with respect to the cutting tool;
- and
- rotating the roll and moving the cutting tool and the roll relative to each other in the axial direction of the roll by position control using C-Z axis interpolation according to the lead angle, thereby forming the three-dimensional pattern in the surface of the roll, and
- repeating the said processes for forming the three-dimensional pattern in the surface of the roll, with setting the next machining start position of the cutting tool and carrying out the C-Z axis interpolation.
