AMC710438 - Aircraft Landing Gear Component | Product | AMC Line Solid Carbide High Speed Machining Tools  | Application | Kellering and Finishing | Sector | Major Aircraft Manufacturers and Job Shops | Work piece | Aircraft Landing Gear Component | Material | Aluminum 7075 T-7351 | Machine | Mazak 5 Axis CNC Vertical Mill | Tool | AMC710438 Three Flute Ballnose Finisher with Extended Reach Length .250" Diameter, .375" Flute Length with 2.125" Extended Reach | Situation | Competitor: Data Flute | Problem | The parts have chatter due to the long reach on a small diameter tool. This requires secondary operations to clean up the part which puts it at risk of being damaged or scrapped. | Solution | The AMC tool was a "Plug-n-Play" tool. It eliminated the chatted and will run faster feed rates than present tool. | Cutting data | Down Cut Vc (SFM) = 1965 sfm V1 (RPM) = 10,000 rpm or 599 m/m fz (Chip load) = .009" or .23 mm ap (ADOC) = .125" or 3.18mm
ae (RDOC) = .188" or 4.78mm | ONSRUD Tool Vc (SFM) = 1965 sfm
V1 (RPM) = 10,000 rpm or 599 m/m fz (Chip load) = .009" or .23 mm ap (ADOC) = .125" or 3.18mm ae (RDOC) = .188" or 4.78mm |
| Benefit | The "Plug-n-Play" capabilities allow the tool to be tested without any changes to the existing programs. This is a huge advantage since NC Programming is the most difficult operation to be changed for a tool test. It eliminated the need for secondary operations to clean out the chatter marks. Now that the tool has replaced the competitor further tests will show the tool will increase productivity due to faster feed rates. This test contributed to a complete start-up order of a major size from one of their sister companies. | Target markets | All solid aluminum parts with difficult to reach pockets |
