Picking the Right Toolholder for the Toughest Jobs August 1, 2015 When sizing up an application for a milling toolholder, it is necessary to consider the materials being machined, how aggressively metal is going to be removed, and any machining conditions that are likely to present a challenge to tooling security. By now, the pros and cons of hydraulic, mechanical, and heat-assisted shrink-fit systems are well known and results well documented.
Interpreting the Language of GD&T in Metrology September 1, 2014 The industrial world is continuing its adoption of Geometric Dimensioning and Tolerancing (GD&T), the advanced tolerancing methodology. The symbolic language is intended to be both more precise while providing more latitude in allowable variations, replacing the simpler method of adding tolerances to each dimension.
A Revolution in Gear Manufacturing June 1, 2014 Machine manufacturers are working to streamline the gear-making process, to deliver a more highly finished gear in fewer steps.
New Metrology Culture Improving Chrysler Quality September 1, 2013 “Five years ago, our fit and finish was below average,” said Dr. Raj Kawlra, director of dimensional strategy and management of Chrysler Group (Auburn Hills, MI). “To be the future world-leaders, we knew that we had to focus on all aspects of quality … vehicles that look good, feel good, sound good, and are reliable.”
Tooling to Match Composite Production April 1, 2009 It’s getting harder to imagine any market that isn’t benefiting from the latest developments in parts manufactured from advanced composites. “Advanced composites will arguably dominate consumer and production products, especially in the near future,” says Bert Erdel, industry consultant and executive technology advisor, Morris Group Inc. (Windsor, CT), “as they have begun to gain wide acceptance in solving energy-related issues.”
Solutions for Difficult Machining January 1, 2009 The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.
Programming CMMs May 1, 2004 Off-line programming software tools for CMMs allow manufacturers to increase measurement capacity and throughput by programming CMMs, probes, and fixtures before parts are made.
What’s the Connection? June 1, 2004 A lot of attention is paid to the “business end” of CNC toolholders–the part that actually holds the tool.
Tooling and Workholding Systems August 1, 2002 “We are developing solutions for power workholding such as hydraulic swing clamps and block clamps, because the real estate on a fixture is so valuable,” says Jason Betz, product specialist for Carr Lane Roemheld (St. Louis). “This pushes the use of smaller workholding components as much as possible because the more parts on the fixture the greater the productivity.”
