Tool Wear of Advanced Coated Tools in Drilling of CFRP

This paper aims to investigate the effectiveness of super-hard ceramic coatings by evaluating tool wear when drilling carbon fiber-reinforced plastics (CFRP) composite. The drilling experiments of CFRP are conducted with diamond-like carbon (DLC) coated, AlMgB 14 (BAM) coated, AlCrN and Si 3 N 4 and TiN (simply denoted as (AlCrSi/Ti)N) coated, and uncoated tungsten carbide drills.

Assessment of Cutting Parameters Influencing on Thrust Force and Torque during Drilling

Drilling which is a secondary machining process is per- formed on fiber reinforced polymer composites (FRPCs) to know the effect of various factors during machining. Drilling is the most widely used for machining of com- posite materials, the effect of thrust force

A Damage

A damage-free cutting method called the constant- load feeding method is proposed as a high-precision machining method in carbon-fiber-reinforced plastic (CFRP) cutting. The constant-load feeding method can minimize cutting defects such as burrs and scuffing during diamond-saw cutting.

Failure characterization of the interface between concrete

Concrete structures are severely susceptible to degradation as a result of mechanical or environmental processes. In most cases, retrofit is the only available option because reconstruction of the deteriorated structure is neither a feasible nor financially practical option. The overall performance of a repaired structure is highly dependent on the properties of its interface, which is the

Infusion of aerostructures: Doubling down on the

Then four plies of 6-oz plain-weave 3K carbon fiber fabric are layed up. Alley buys the carbon fiber from multiple sources, noting that price is the primary criterion in his selection of material. "A cowling is more like a fairing in that there is no structural loading on the part.

Cutting Forces in Milling of Carbon Fibre Reinforced Plastics

The machining of fibre reinforced composites is an important activity for optimal application of these advanced materials into engineering fields. During machining any excessive cutting forces have to be avoided in order to prevent any waste product in the last stages of production cycle. Therefore, the ability to predict the cutting forces is essential to select process parameters necessary
