A Dual Personality: Industry Trends & Analysis
Numerous factors determine whether a manufacturer is profitable or not. Lately, one of those factors for a U.S. manufacturer is whether it is is focused on the domestic market or pursuing a global approach.
Industry’s Image Issue: People & Companies
The results from a recent SME survey of parents about their views relating to careers in manufacturing showed there is not enough accurate information about the opportunities a manufacturing career offers.
More Help for Engineers: People & Companies
In last month's column, I discussed the value of communication between engineers and shop personnel.
Technology Targets Crashes: 5-Axis Machining
As CNC machining gets more complicated, the chance of programmer and operator errors increases. These errors can cause collisions involving machine components and workpieces during the cutting process, resulting in downtime and part, tool and machine damage. Costly crashes aren't inevitable, however, thanks to technologies aimed at preventing collisions and minimizing their impact.
A Very Formal Visit: People & Companies
When a good customer requests a meeting at his place, I go. That happened recently, when our shop's account manager accompanied me on a 20-minute trek to a customer's new corporate headquarters for a meeting to review our contract and extend it a few years.
Coming Revolution: Inspection Efficiency
Contrary to the history lessons from middle school about "the" Industrial Revolution, it is a widely held belief that the modern world has experienced three industrial revolutions. In the first, industry harnessed the power of steam and water. Mass production, reliable electrical power and division of labor drove the second revolution. Electronics and the computer defined the third.
Q&A: Deep-Hole Drilling
Deep-hole drilling is virtually an art unto itself, with a host of complexities and considerations inherent to the process. Greg Forman, technical director of toolmaker Precision Cutting Tools Inc. (PCT), Santa Fe Springs, Calif., answered questions to provide some insight into drilling holes greater than 5 diameters deep.
A Simple Diagnosis: General Industry Coverage
It's not the most glamorous piece of equipment by any means, but the ball bar is a diagnostic tool used, in some form, to benchmark the performance of virtually every machine tool sold, according to Harold Schoch, vice president of technology and sales for Konecranes, Erlanger, Ky.
High-Pressure Work: General Industry Coverage
Components used in the manufacture of combustion hardware for a Mitsubishi gas turbine begin life as sheet or plate stock. Because our components come from large sheets, we start every manufacturing process by cutting the desired shape or profile.
Multibenefit Machines
CNC lathes have evolved greatly over the past few decades. What were once simple 2-axis turning machines have become a bewildering array of extremely capable metalcutting equipment, most of which offer two spindles, multiple turrets, robust milling capabilities and can complete many parts in a single setup. In other words, they have become multitask machines.
Clamp Down: General Industry Coverage
The technology to form, press and grind indexable carbide inserts has evolved to such a high degree that the methods to effectively clamp inserts in a cutter body have struggled to keep up, but strides are being made. Some insert shapes have advanced to the point where they have a true, 100-percent, 3D geometry with almost no flat surfaces.
Cutting remarks: General Industry Coverage
Michael Finklea believes that there isn't much reported on sawing in the manufacturing trade press because "it's kind of the redheaded stepchild in the industry—an unappreciated part of the manufacturing process. In most shops, the least-skilled person is running the saw."
