New Concepts in 5-Axis Blisk Machining

Autodesk and UK based cutting tool specialist Technicut have jointly developed new tooling concepts and toolpath strategies for machining blisks (bladed disks). Manufactured from titanium and nickel, these highly complex and critical components are becoming more common due to the advantages of weight, efficiency and through-life servicing.

This patent-pending process, which combines innovative tooling solutions and application strategies for the roughing, semi-finish and finish machining of all integrally bladed rotors, has provided a 51% time reduction to machine a blisk from start to finish.

"Through our Productivity Solutions, we are able to demonstrate significant reductions in machining cycle times and total production costs for either current or planned components, and deliver both optimized `mini-turnkey' and `green-button' packages for their complete manufacture," said a spokesperson.

The blisk machining strategies utilize Autodesk's PowerMill blade, blisk and impellor module. Technicut's optimized titanium roughing solutions use X-TREME shanks in combination with Nikken Kosakusho's X-TREME milling chuck for enhanced workpiece security. Features include:

• Heavy-duty cutting capability
• Accurate clamping technology
• Zero tool pull out and tool micro-creeping elimination
• No damages to workpiece or machine

"Our focus is to continually enhance our customers' competitiveness through the supply of optimized tooling and application methodologies," said the spokesperson.

Productivity solutions include:

• Recommendation of best cutting technologies
• Generation of innovative application methodologies
• Provision of 5-axis part programming and machining
• Provision of first part prove off.

Additional features and benefits:

• Optimized machining strategies for highly complex shapes and closer blade spacing
• Reduced cycle times through near-net-shape roughing
• Enhanced component finish and surface quality
• Stable and repeatable process
• Low heat input for minimized distortion and improved dimensional conformance
• Non machine tool specific with low spindle loads
• Low-vibration machining
