Problems solved by technology

At this time, the mechanical resonance phenomenon can be used to efficiently obtain a cutting depth of micron order, but since the vibrator vibrates in a sinusoidal waveform, the shape of the processed surface obtained is limited to a periodic shape that depends on the sinusoidal wave trajectory of the tool tip

Embodiment Construction

[0034] figure 1 A schematic structure of the cutting device 1 of the embodiment is shown. The cutting device 1 is a machining device that performs turning-like processing by reciprocating the cutting edge of the cutting tool 11 with respect to the workpiece 6 . The cutting device 1 of the embodiment is a roll lathe that turns a cylindrical workpiece 6 to produce a rolling roll, but it may be another type of cutting device. Typically, the material to be cut 6 is die steel, copper material, aluminum material, etc. whose surface is electroplated with nickel phosphorus, but it may also be other materials.

[0035] The cutting device 1 includes, on a machine base 5 , a headstock 2 and a tailstock 3 for rotatably supporting a material to be cut 6 , and a tool post 4 for supporting a vibrating device 10 to which a cutting tool 11 is attached. In addition, the cutting device 1 has at least a feed mechanism for moving the tailstock 3 relative to the headstock 2, a feed direction for ...

Abstract

A cutting apparatus (1) comprises a cutting tool with a cutting edge, an excitation unit (15) for exciting vibrations in the cutting tool, and a driving unit (30) for applying voltage to the excitation unit (15) so as to cause the cutting edge of the cutting tool to oscillate. The excitation unit (15) involves excitation forces with higher frequency components than a resonance frequency and carries out excitation with a reduced excitation force at the resonance frequency so as to suppress residual vibrations. The excitation unit (15) carries out a first excitation, and carries out a second excitation for suppressing residual vibrations from resonance after the passage of time equaling to 0.5 times the period of the resonance from the time of the first excitation.

Description

technical field [0001] The present application relates to a technique for cutting the surface of a material to be cut by vibrating a cutting tool to displace a cutting edge. Background technique [0002] Microtexture processing is a technique for controlling the mechanical properties of a processed surface by forming a fine periodic structure, and applied research is being carried out in various fields. For example, it is known that a microtexture functioning as an oil pool can be formed on a sliding surface using lubricating oil, thereby reducing the coefficient of friction and wear, and achieving high lubrication with a small amount of low-viscosity lubricating oil. [0003] Consider the following method: In the case of machining micro-textures, the vibrator on which the cutting tool is attached and the workpiece are relatively moved, while the tip of the cutting tool is reciprocated relative to the workpiece to form the machining noodle. At this time, the mechanical res...
