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
