Pushing Productivity to the Limit: High Speed Machining of Brasses

Tue. April 25| 1:00 PM - 1:30 PM |

New findings from an extensive machinability research project on brasses will be presented to demonstrate that both leaded and lead-free alloys can be machined at cutting speeds and feed rates significantly higher than current practice and recommended handbook values. A basic business case will be reviewed to illustrate the productivity gains and cost savings that can be achieved with brasses through high speed machining.

After this session, participants will be able to:

1) Identify stable high speed machining conditions for leaded and lead-free brass alloys across turning, drilling and milling operations.

2) Understand the impact of increasing cutting speed, feed rate and depth of cut on key productivity indicators including: power factor, tool life, surface finish and chip formation.

3) Calculate spindle power requirements for high speed turning, drilling and milling on leaded and lead-free brasses.

4) Understand how different types of cutting inserts perform on brasses under high speed conditions including high speed steel, carbide and polycrystalline diamond.

5) Gain insights into optimizing machining parameters for brasses, and selecting machine tools with capabilities best suited to minimize capital costs.

6) Understand the business case and cost savings that can be realized through high speed machining of brasses.
