Basic FormabilityTransfer Curves

1 day course


Learn the development, generation and use of transfer/interference curves for both tri-axis and crossbar systems. Also included is the influence that transfer curves have upon both the process planning and die design phases. Students will be challenged with exercises to verify the transfer of a part in a die operation.
