AI Technical Summary
Existing ball end mills, when machining fiber-reinforced composite materials, suffer from high cutting forces, severe vibrations, and difficulty in heat dissipation, resulting in poor machining quality and accelerated tool wear.
Design a ball end mill with a helical structure, including a helical chip removal groove and a helical chip tolerance groove. The ball end mill is divided into multiple micro-tooth milling cutting edge units. The helical chip removal groove and the ball end mill are connected to form multiple rows of micro-tooth milling cutting edges. The chip removal groove is connected to the ball end mill, forming an orderly arrangement of micro-tooth milling cutting edge units, which reduces cutting force and facilitates heat dissipation.
It effectively reduces cutting load, improves cutting efficiency, reduces vibration, improves machining quality, extends tool life, improves the heat dissipation performance of fiber composite materials, and avoids damage caused by local high temperature.
