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.
How Indexable Tools Keep Their Edge April 22, 2020 Sales figures don’t lie: indexable cutting tools—featuring removable cutting tips called inserts—are a smash hit with machine shops.
Live Tooling: Basic Concepts, Recent Developments April 24, 2020 Live tooling, as the name implies, is driven by the CNC and the turrets of various spindle and powered sub-spindle configurations on CNC lathes.
Measurement Accuracy: What You Need to Know April 23, 2020 It’s an old challenge: You’re a manufacturer whose customer needs you to assure that the part you’ve contracted to make for them will be held to specified tolerances. So, what’s the best method for making sure the part is within spec?
Shops Use Shrink-Fit with Presetters for Toolholding Efficiency April 15, 2020 Unlike its name, the use of shrink-fit tooling is expanding. A shrink-fit toolholder starts with a slightly undersize bore that is heated to enlarge the inner diameter enough to accept a cutting tool and then grip the cutter as it cools and contracts.
Replaceable-Tip Tools Get Permanent Spot in Shop Inventories April 13, 2020 When weighing the choice of replaceable-tip mills and drills or solid-carbide tools, consider this succinct statement from one industry expert: carbide equals cost.
How to Choose the Best Toolholding System for Your Shop April 16, 2020 Many job shops hold onto traditional, inexpensive tooling systems. ER collets and Weldon flats are tried and true; they work and are proven. At the same time, newer, advanced machining technology, such as multi-axis machines, may perform better when newer, advanced (and more expensive) toolholders are deployed.
Rough Boring vs. Finish Boring April 16, 2020 There’s more than one way to finish a hole. The most effective option will depend on the number of parts, cycle time and tolerances. One of the most effective options is boring.
Modular Quick-Change Systems Not Created Equal April 17, 2020 While the initial investment for a modular quick-change tooling system is higher than that of traditional toolholders, significantly improving the connection between spindles and tooling is well worth it.
