Buyer Beware: Supply Chain & Logistics
This article warns against the dangers in recent manufacturing supply trends. According to the author, both outsourcing and integrated-supply programs can have seriously detrimental effects on productivity and innovation. In this article, he explains the reasoning behind his views.
Absolute Zero: General Industry Coverage
When digital calipers that did not have to be zeroed before each measurement were introduced, they represented a significant advancement in electronic gaging. This article explains the technology behind these absolute-reading instruments and how they are used to make typical shop-floor measurements.
Itching for a Solution: Safety, Standards & Compliance
This article reviews the causes of skin irritation suffered by some shop workers, with special attention paid to skin conditions that result from poorly maintained metalcutting fluids. The article also discusses the factors that can aggravate skin problems and suggests ways that workers can protect themselves from skin irritants.
Grinding With Segments: Heavy Stock Removal Guide
Segmented grinding wheels can help in heavy stock-removal applications with large contact areas. This guide covers where grinding segments fit and what shops should watch.
On Boring’s Cutting Edge
Although machinists are using cermet and ceramic cutting tools for an increasing number of applications, they have been slow to adopt them for boring. This is beginning to change, however. This article describes some of the ways a boring operation can benefit from the use of these tools.
Countersinking Aircraft Materials
This article traces the changes in countersink design and materials that have been made to satisfy the demands of the aerospace industry. The advantages and disadvantages of different types of modern countersinks are discussed.
Workholding Goes to Great Lengths
When shouldered parts are held for turning with a draw-in collet, length-control problems can result. This article provides directions for making collet add-ons that allow the machinist to locate the part against the spindle face, providing a consistent length from part to part.
Getting a Grip on Productivity
This article guides the reader through the many decisions that must be made when selecting and installing a hydraulic workholding system. Basic hydraulic system design principles and maintenance also are discussed.
Know What You’re Tapping
Traditional tap/drill charts recommend drill diameters for each size of tapped hole. But, according to this article, these recommendations are based on the size holes that were typically produced by less-accurate tools and processes used in the past. This article suggests guidelines for producing holes that will, in turn, produce correctly sized tapped holes.
Coolant Care
By recycling used metalworking fluids, shops can realize considerable savings in fluid and disposal costs. This guide takes the reader through the fundamentals of fluid recycling and management. Excerpted from a manual on the subject, the piece covers both the care and cleaning of fluids and fluid-handling equipment.
Ball-Drive Superiority: Drilling Performance
This article makes the argument that ball-drive quick-change tapholders, which transfer torque through hardened-steel balls fitted into mating detents, are more reliable than tang-drive units. The technology behind ball-drive tapholders and the design's benefits are explained.
Burning Brightly: Turning Performance
The more sophisticated die-sinker EDMs on the market today possess enough intelligence to monitor cutting conditions and make necessary adjustments on the fly. This article describes the technology that drives these smart machines and the "fuzzy logic" they use to maintain an optimal spark.
