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.
DIY: Creating Through-Tool Coolant Capability June 1, 2015 New retrofit systems make it possible to quickly, easily and cost effectively transform the standard external-coolant live tooling heads on turning machine turrets into those with through-tool-coolant capability. And shops that have done the retrofit are experiencing longer tool life, more efficient chip control and less heat generation.
Machine Vision Inspection Speeds Up Automotive Lines May 1, 2015 As machine vision technologies improve, providing more data more frequently, new uses for inspection during the manufacturing process are emerging. The automotive industry might represent the ultimate challenge to providers of machine vision equipment used in robotic guidance and material inspection.
The Increasingly Perfected Science of Machining Composites April 1, 2015 A 1965 Shelby Cobra 427 shown at the Detroit Auto Show was additively manufactured on a Cincinnati BAAMCI machine by DOE’s Oak Ridge National Laboratory (ORNL), one of seven founding members of the Institute for Advanced Composites Manufacturing Innovation. The Detroit IACMI branch will get $70 million to develop a robust supply chain to improve materials, handling, and machining properties for automotive composites.
Milling vs. Grinding for Rapid Stock Removal February 16, 2015 A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.
Extrusion and Drawing Knowledge January 2, 2015 Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.
Change-up Pitch: From Metal to Plastic October 2, 2014 Even though it’s been around since the 1950s, when engineering-grade resins were first introduced, many manufacturers still are not familiar with the many benefits that metal-to-plastic conversion provides.
Innovative Tools Remove the Jagged Edges October 1, 2014 Don’t overlook advanced technology available for removing the gnarliest burrs from parts large or small
Mix and Match for Lightweight Autos September 1, 2014 It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort.
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.
