Cutting angle acquiring method for restraining milling burr of carbon fiber laminate

Abstract

The invention discloses a cutting angle acquiring method for restraining milling burr of a carbon fiber laminate. The method comprises the following steps: constructing a calculating model for milling burr and cutting force angle of the carbon fiber laminate; acquiring the cutting angle with the cutting force parallel to a carbon fiber layer; accordingly designing an orthogonal experiment for comparing the burr defect under an appointed technical condition; selecting the cutting angle for effectively restraining the milling burr of the carbon fiber laminate. According to the method provided by the invention, the structure modification for machine tool is not required and the method has the advantages of simple and convenient operation, high calculation efficiency and high practicability.

AI Technical Summary

Benefits of technology

This new technology helps prevent damage from small cracks or imperfections during processing of composites made up by layers of fibers. By millering it slightly beyond an angled cut-off line, these flaws can become less visible compared to previous methods without this technique being applied. Additionally, if there were any differences between different materials for example due to changes over time (such as temperature), adjustments could also affect how well they work together.

Problems solved by technology

Technological Problem addressed in this patents relating to the use of carbon fibers for various purposes including making composite structures like vehicles or airplanes due to their superior physical performance compared to traditional metals (such as steel). These composites require specialized techniques involving machining processes called sandwich blinds, which involves laying up individual sheets of preform beforehand without damaging them while they still hold together tightly enough to resist deformation under heavy loads. Additionally, these compositions must exhibit improved durability over long periods of operation because they often experience severe impact from external factors such as temperature changes, moisture absorption, abrasion, etc., causing cracks and fractures.
