Aerospace – Fuselage Frame

Tooling concepts

• Improves productivity and prevents chattering on thin wall parts
• Application of low cutting force tools to achieve high speed and high D.O.C
• In order to maximize the performance of the 5-axis machine, apply multi-functional tools and machining methods such as ramping and contouring

Process 1: Rough face milling

Benefits

• The V-shaped bottom geometry securely clamps the insert against centrifugal force. Enables stable, high-efficiency machining at extremely high cutting speeds
• Shoulder milling cutter with long cutting edge length for high depth of cut machining. Reduced machining time for rough milling process
• Cutting force is reduced by combining a sharp cutting edge and a large rake angle
• Polish treatment on the rake face of the insert reduces adhesion and achieves excellent machined surface quality

AJ chipbreaker

• High accuracy grinded insert
• Excellent machined surface quality by built in wiper edge

Process 2: Finish face milling

Benefits

• Polishing treatment on the rake face of the insert reduces adhesion and achieves excellent machined surface quality
• Cutting force is reduced by combining a sharp cutting edge and a large rake angle
• Highly rigid body design and high density for high productive machining
• Lineup of cutters with internal coolant channels. Wet machining contributes to excellent chip evacuation and improved machined surface quality

AJ chipbreaker

• AJ chipbreaker dedicated to aluminum machining and grade TH10 are available
• High economical insert with 10 edges

Process 3: Rough shoulder milling

Benefits

• High-productive rough milling by the vibration suppression effect of the wave-shaped cutting edge
• Chips are finely divided even in aluminum machining where chips are likely to be long and connected due to the wavy cutting edge

TERC-E3

• Roughing end-mill with 3 flutes and 38 deg helix
• KS15F grade keeps edge sharpness and prevents welding

Process 4: Finish shoulder milling

Benefits

• Polishing treatment and a large rake angle prevents the occurrence of built-up edge that tends to occur when machining aluminum alloys. Maintains excellent machined surface quality
• A head can be combined with a carbide shank. Prevents chattering that tends to occur during long overhangs, and maintains high accuracy even in deep area machining

VEE-A03

• Cutting edge design specialized for aluminum machining
• Welding is prevented by polishing treatment

Process 5: Finish profile milling

Benefits

• Strong rake angle design for low cutting force. Prevents chattering
• Abundant shank lineup allows adjustment of the optimum overhang length. Secures tool rigidity and contributes to maintaining dimensional accuracy

VBE-BGA

• Head exchange type tool supports easy management
• Excellent adhesion resistance due to polishing treatment
