Why is the carbon fiber milling cutter easy to entangle chips?

In the carbon fiber machining scenario, milling cutter chip entanglement is a headache for many practitioners. It not only slows down the machining rhythm, but also may affect the machining accuracy, damage the tool, and even lead to the scrap of the workpiece. So, why is the carbon fiber milling cutter especially easy to wrap chips? Today, we will come and Zhongye da editorial together to understand.

First, the root cause

Material properties

First of all, carbon fiber composite material consists of carbon fiber reinforcement and resin matrix. High hardness, high brittleness of the carbon fiber is easy to produce short chips, and the resin matrix is softened by heat viscosity, the chips will be bonded into a mass winding carbon fiber milling cutter, the combination of its hard and soft characteristics to increase the difficulty of chip removal.

Structural design defects

Secondly, small and poorly shaped chip holders prevent chips from being discharged in a timely manner, and the blunt cutting edge aggravates the deformation of material extrusion, which are two factors that increase the risk of chip entanglement.

Improper processing parameters

One point that cannot be ignored is that too low a rotational speed causes cutting heat to accumulate, and too slow or too fast a feed will lead to excessive chip fragmentation or delayed discharge, and too large a depth of cut exceeds the capacity of chip removal, all of which will lead to chip entanglement.

Second, chip removal solutions

Optimize the design of cutting tool: Adopt spiral milling cutter with large chip holding groove, sharpened with high precision, and coated with DLC anti-adhesion coating.

Adjustment of processing parameters: reasonably increase the rotational speed to reduce cutting heat, match the material characteristics to set the feed rate, and use layered cutting to control the amount of chip generation.

Reinforcement of auxiliary measures: use lubricant-containing cutting fluid to reduce temperature and remove chips; during dry machining, blow the cutting area directionally by high-pressure air.

In short, carbon fiber milling cutter chip entanglement, the nature of a variety of factors superimposed on the results. We want to solve efficiently, as long as these methods to eat through, live, in order to make carbon fiber processing chip removal smooth, efficiency, precision double enhancement, do not have to worry about chip entanglement.
