PPT-Simulation of chip formation during high-speed cutting

Authors Christian Hortig and Bob Svendsen Jordan Felkner October 5 2009 Purpose Model and simulate shear banding and chip formation during highspeed cutting Carry out a systematic investigation of size and orientationbased meshdependence of the numerical solution. Rache Corporation provides laser cutting, laser welding and Laser Marking services to a wide range of industries including medical devices, microwave components, aerospace, automotive and more. We are organized to provide cost effective laser solutions to industrial challenges in a customer-comes-first environment.

In cutting process, the major . independent variables. , that is, the variables that we can change and control directly, are :. Machinability. Tool Life. Useful cutting life of tool expressed in time. Time period measured from start of cut to failure of the tool. Time period b/w two consecutive resharpenings or replacements.. Offer. .

Speed skating is a competitive form of ice skating where competitors race each other in travelling a certain distance on skates. Men compete in 500m, 1,000m, 1,500m, 5,000m and a 10,000. In each event, skaters race in pairs against the clock on a standard 400m oval ring. All events are skated once, apart from the 500m, which is skated twice. In this case, the final result is based on the total time of the two races. (feed force). Main Cutting force. Radial force. Tool feed direction. Topics to be covered. Tool terminologies and geometry.
