45 / CUTTING OIL SAVES SHOP THOUSANDS
Many metalworking shops buy their cutting oils based strictly on price. While this might appear initially attractive on the procurement side, it often leads to a false economy when the total increased costs of tooling, down- time, and scrap, not to mention unhappy operators, are considered.
50 / SOFTWARE HEADS OFF COSTLY CODE REWORK, CRASHES
Computape (Monticello, MN) was founded in 1976 by Ed Popp, an NC Specialist working for General Electric, in a time when most machine tools still had hand cranks and levers. There was no C in CNC back then.
69 / EDM’S HOME FIELD ADVANTAGE
Changes in manufacturing including more use of hard-to-machine metals, play to EDM’s technology.
79 / NEW TECHNOLOGIES RAISE THE BAR FOR ABRASIVE WATERJETS
Fast, higher-pressure abrasive waterjets cut parts much quicker, reducing job-shop costs and improving productivity.
87 / MANUFACTURING SOFTWARE HELPS SHOPS MAP LEAN JOURNEYS
With scheduling, monitoring and quality analysis software, manufacturers visualize the factory fl oor to help reduce waste and reach their lean manufacturing goals.
95 / CNC MAKES GRINDER REBUILD LOOK EASY
“When ASB Industries called us with a rebuild application for a Mesta Roll Grinder with a 60" [1.5-m] swing and 288" [7.3 m] between centers, we knew we were going to be stepping it up a notch or two on this job,” said Jim Leigh.

FLUTE GRINDING TODAY A fl ute remains one of the most diffi cult features to grind in round tool manufacturing, especially in today’s tougher materials, such as high-speed steel (HSS) or tungsten carbide. A senior applications engineer with Saint-Gobain Abrasives talks about the importance of choosing the right abrasive and wheel geometry. More at

Cover: Here, a high-pressure waterjet from Flow International Corp. (Kent, WA) cuts nested metal parts. Flow, like its competitors, has worked diligently to deliver signifi cantly higher pressure, which can reduce waterjet cycle times and operating cost. In this issue, Senior Editor Patrick Waurzyniak writes about the latest developments in waterjet technology, which is helping the technology expand into the broader market.
