Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
The challenges to manufacturing as it evolves into the 21st century are now familiar, and impact how metrology must contribute. Manufacturers face uncertain production volumes with roller-coaster demand, shorter production runs and faster product development cycles. Automation, while alluring as a way to reduce cost, needs to adjust.
Today’s products require high finishes, burr-free edges, freedom from contamination, and often close tolerances. Electropolishing provides all of those conditions and more in a matter of seconds for many metal parts. It is a process that has been used for more than a hundred years. It is widely known and the science is widely discussed, but its ability to run job shop lots and high-precision high-volume parts in the same equipment makes it a bit unique.
It is reported that, not too long ago, before the current precipitous decline in machine-tool shipments, the number of 30-taper machines that were being manufactured and sold in Japan had surpassed the numbers of 40-taper and 50-taper machining centers.
Glenn Bridgman describes the difference between his shop’s manual grinders and its newest state-of-the-art CNC ID/OD grinder, a Studer CT960 OD/ID from United Grinding (Miamisburg, OH), as “feel vs. facts.” Bridgman, president of Bridge Tool & Die (Buckley, MI), believes that manual grinding is a somewhat personal operation.
The concept of attaching data to CAD models, such as GD&T, seems to be growing. Using model-based definition, the industry is beginning to take advantage of the technique.
Seco Tools LLC (Troy, MI) hosted a Mold and Die Manufacturers Seminar for metalworking professionals at its headquarters on July 26 in collaboration with hyperMILL (Open Mind Technologies, Needham, MA) and Heidenhain Corp. (Schaumburg, IL).
GE Appliances (GEA) has been designing and manufacturing consumer appliances for over 125 years. The iconic brand, headquartered in Louisville, KY, employs nearly 6000 people, a number that rose to 12,000 employed globally after its acquisition by Haier, making the company part of the largest appliance manufacturer in the world.
A new report urges the United States invest in emerging manufacturing technologies, saying the private sector can’t preserve US manufacturing by itself.
Tool presetting machines are a wise investment for machine shops that want to increase their machine utilization. Idle machine tools are often indicators of inefficient machining operations, and stopping a machine tool for any reason is synonymous to losing profits.
