How Simulation Improves Machining Tool Design and Performance
Computer simulations of the cutting process can help tool designers predict the effects of tool-geometry changes. This article describes how one manufacturer is using the most recent advances in computer modeling to reduce the need for producing and testing prototype inserts. An accompanying article describes a commercially available simulation program.
Sawing In-House vs. Outsourcing: What Shops Should Consider
An increasing number of shops are purchasing saws and bringing their cutoff operations in-house. This article discusses the benefits of such a move and explains the factors that must be considered before selecting a saw. Blade selection is also discussed.
Frenzied Feeding: Turning Performance
By changing the nose radius of their finish-turning inserts, toolmakers are producing wiper inserts that allow machinists to turn workpieces at increased feed rates. This article explains the theory behind this innovation and describes the specific wiper-style geometries employed by three manufacturers.
Pain-Free SPC
Experts offer advice for implementing an SPC program in shops. They emphasize that developing an SPC program isn't as difficult as many people think, and that a program can be implemented with few hassles.
The Pressure’s on to Improve Drilling
The author explains how high-pressure, high-volume coolant can provide better control of chips and temperature during drilling operations. He also describes the tools, equipment and shop procedures that can ensure top performance from a high-pressure coolant system.
Machinability of Sintered Steel: Drilling Performance
Researchers from Lehigh University report the results of drilling tests conducted using sintered steel samples. The samples were prepared using different machinability-improving additives. The results showed that sintered steel with low-alloy steel and resulferized sintered steel are nearly as machinable as wrought steel.
PVD Coatings for Turning
Researchers report on their study of coating performance. Their tests of TiN, TiCN and TiAlN coatings involved turning Inconel 718, medium-carbon steel and ductile cast iron. The wear rates and failure mechanisms of the coated tools are compared.
Getting Peak Performance from Indexable Drills
Indexable-drill performance depends on insert selection, toolholding, coolant, and hole-entry conditions. This guide covers the setup details that most affect results.
Coatings Move Forward: Drilling Performance
The PVD and CVD processes produce coatings with specific strengths and weaknesses. This article compares the processes and attempts to correct some common misconceptions about CVD coatings. The findings of a survey on tool coaters' use of coating materials and methods are also reported.
Staffing Shortage Stymies Metalcutting Shops
An exclusive survey finds shops struggling to locate and hire skilled labor. This report of the survey's findings also reveals the most popular techniques to ease staffing woes.
CMM Made Easy
Next-generation CMM software offers users a simple interface, the ability to program the machine directly from CAD data files and the opportunity to write programs off-line. This article describes the latest advancements in CMM software and shows how older machines can be retrofitted to take advantage of the software's features.
Learning With an Edge: General Industry Coverage
Using his students as researchers, an industrial-arts teacher sets up an experiment to test claims being made for tool resharpening using cubic boron nitride wheels. The experiment taught the students how to keep a log of tool conditions, use and sharpenings as they gathered data for their study.
