A critical flaw exists in V-Flange tooling used in CNC machining. This flaw translates to issues that are present industry-wide: vibration, chatter, run-out, poor tolerances, lack of repeatability, shortened tool life, lengthy set-up time, excessive spindle wear and tear. John will describe the how to identify the problem, the cause of the problem, and finally how to correct the problem. He will illustrate the cost of the flaw and the potential bottom line gains that can be achieved by making simple corrections to existing equipment. John’s presentation will include case studies that support his position that CNC V-flange can be the most accurate, affordable and productive tooling system available.
