AI Technical Summary
Technical Problem
Existing removal processes for metal parts, such as cutting, grinding, and polishing, suffer from tool wear and damage due to metal adhesion, leading to reduced tool life and decreased dimensional accuracy.
Method used
A method involving the use of a machining fluid containing fine bubbles generated by a fine bubble generator, applied during the removal process, where the power consumption and metal removal rate are controlled to maintain an optimal number density and size of fine bubbles, adsorbing the removed metal material and preventing adhesion.
Benefits of technology
The method extends tool life by effectively removing adhered metal material, maintaining tool integrity and accuracy during the removal process.

Abstract
To provide a method for manufacturing metal components that can improve tool life of a removal processing tool.SOLUTION: In a method for manufacturing metal components according to the present disclosure, a fine bubble generation step generates fine bubbles in a processing liquid PF using a fine bubble generation device 3. A removal processing step performs removal processing by bringing a removal processing tool 1 into contact with a metal material W. A processing liquid supply step supplies the processing liquid PF containing the fine bubbles to a portion of the removal processing tool 1 that is in contact with the metal material W and / or a portion of the metal material W that is in contact with the removal processing tool 1, during the removal processing. During the removal processing, a power P (Wh), which is an average power per one hour of removal processing time for the fine bubble generation device 3 to generate fine bubbles, and a removed metal quantity M (g / second) per unit time, which is an amount of metal removed from the metal material W by the removal processing, satisfy Formula (1): (1) 30<P / M<300.SELECTED DRAWING: Figure 1
