AI Technical Summary
Technical Problem
Existing cutting inserts are designed without considering chip removal, which causes heat to be generated by the friction between the chips and the insert, increasing the risk of wear and chipping.
Method used
A cutting insert is designed, comprising an arc-shaped cutting edge, a chip breaker groove, and a flow guide groove. The flow guide groove is formed between the chip breaker groove and the rake face by a raised portion to improve structural strength. The flow guide groove and chip guide ridge improve chip discharge smoothness and cooling efficiency.
Benefits of technology
It effectively reduces the wear and chipping risk of cutting inserts, extends their service life, and improves cutting efficiency and cooling effect.

Abstract
The invention discloses a cutting blade and a cutting tool, and relates to the technical field of cutting tools, the cutting blade is provided with an upper wall surface and a side wall surface, a cutting edge is formed at least partially at the intersection of the upper wall surface and the side wall surface, the cutting edge at least comprises a tool nose cutting edge extending in an arc shape, and the upper wall surface is provided with a front tool surface, a chip breaker groove and a top surface. The upper wall face is provided with a protruding part corresponding to the tool nose cutting edge, at least part of the protruding part is located in the chip breaker groove, the protruding part extends to the front tool face from the top face, a flow guide groove is formed in the protruding part, and the flow guide groove extends to the front tool face from the top face. The protruding part is arranged and can be at least supported between the groove wall of the chip breaker groove and the front tool face, so that the structural strength of the cutting blade is improved; a flow guide groove is further formed in the protruding part, chip curling is facilitated, chip removal smoothness is improved, the risk of chip blockage is reduced, meanwhile, the flow guide groove can guide cutting fluid, the cooling efficiency of the cutting blade is improved, and the risk of tipping or damage of the cutting blade is reduced.
