Abstract
The present invention provides a cutting method comprising a cutting step of cutting a workpiece material with a cutting tool to thereby form a through-groove in the workpiece material, wherein in the cutting step, the through-groove is formed in the workpiece material by cutting the workpiece material with the cutting tool while contacting a cut-assisting lubricant with the contact portion of the cutting tool with the workpiece material and/or the contact portion of the workpiece material with the cutting tool, and the workpiece material comprises a fiber reinforced composite material.
Claims20
A cutting method comprising cutting a workpiece material with a cutting tool, the workpiece material and/or the cutting tool being contacted with a cut-assisting lubricant, to thereby form a through-groove in the workpiece material, wherein:
- the cut-assisting lubricant comprises:
- i) a compound (A) having a weight average molecular weight of 5.0×104 or higher and 1.0×106 or lower,
- ii) a compound (B) having a weight average molecular weight of 1.0×103 or higher and lower than 5.0×104, and
- iii) a carbon (C) having an average particle size of 100 μm or larger, and
- the workpiece material comprises a fiber reinforced composite material.
