Cracking the Code: Turning Performance
This article reviews the nomenclature that toolmakers use to identify inserts. Both ANSI and ISO codes are described character by character. A chart lists all of the possible choices for each position in the code and what each code letter or number signifies.
PCBN Turns the Hard Stuff
This article compares hard turning to grinding for finishing hardened steel parts and discusses which operation would be more appropriate for various situations. The article also looks at the machine tool, insert and cutting parameters required during hard turning.
Honing Comes Full Circle: Turning Performance
Honing was originally a surface finishing operation that did not remove significant amounts of material. This article discusses brush honing, a process the authors say produces results similar to what honing was originally intended to produce. Proper boring is also discussed, because, according to the authors, a properly bored hole will not require further correction through modern aggressive stone honing techniques.
Barfeeding Advances: Drilling Performance
According to this article, the short-bar barfeeders that are on the market today are not plagued by the drawbacks that have become associated with barfeeding. The units load 5-foot bar stock into a lathe rather than the longer stock loaded by earlier units.
Optimal Automation
The efficiency of a die-sinker EDM operation can be enhanced by automating at least part of the work handling or tool handling. This article describes the automation that is available, from the simplest electrode grippers to fully automated toolchanging systems.
EDM Conquers Copper: Settings and Electrode Guide
Copper can be difficult to EDM because its thermal conductivity changes electrode wear and process behavior. This guide covers the settings and strategy shops should review first.
CVD Diamond for Everyone: Turning Performance
It took years to perfect, but manufacturers finally found a way to economically coat carbide inserts with a diamond film. This article describes the coating process and looks at that companies that are offering diamond-coated tools, the companies that are coating tools for other manufacturers and the companies that are supplying coating equipment. Thick-film diamond is also discussed.
Squared Straight
Three different problems can cause a laser to make beveled cuts. As these problems interact, they create distinct patterns of bevel angles that require sophisticated mathematical analysis to sort out. This article discusses an experiment using Fourier analysis to determine which combination of problems caused the cyclical variation that was observed in the measurements of a laser's cutting angle.
Carbide Coatability: Trade Shows & Events
A clear and intact substrate surface is important to the success of a coating deposited on a carbide insert. This article looks at the surface problems and contamination, introduced by the insert manufacturing process, that the coating company or insert user must correct before the insert is ready to be coated.
Saving Saw Bucks: People & Companies
Advancements in bandsawing are allowing shops to closely control the cost and precision of the operation. This article looks at such innovations as informational computer programs that provide advice on workpiece positioning and machine settings. Improvements in blade design and the applicability of these new blade geometries is also covered.
A Simple Groove: Turning Performance
This article discusses the trend among insert makers to consolidate chipbreaker designs and carbide grades. The result is the three-chipbreaker/three-grade matrix many insert makers have adopted in some form. The evolution of the chip-forming groove is also traced, and an ANSI proposal for a grade identification system is described.
Bushings Get It Straight
Guide bushings are used in difficult holemaking applications to ensure that the drill produces round straight holes. This article discusses the types of bushings commonly used and the materials they are made from. Guidelines for sizing bushings for a given operation are also supplied.
