Challenged by an increasingly niche-oriented automotive market, The Chrysler Group (Auburn Hills, MI) must increase the number of models it offers while decreasing its capital investment. The company plans to offer 50% more models in 2009 compared to 2004, according to John Felice, VP of manufacturing, technology and global enterprise for Chrysler.

Nothing seems so obvious in subtractive machining than that milling and turning processes really are very different: single point vs. multipoint tools; rotating workpiece vs. rotating tool; static tool vs. rotating tool, etc.
The U.S. Navy has awarded Northrop Grumman Corporation (NYSE: NOC) a $9.6 million contract, with options up to $40.5 million, to produce the Transducer Array/Nose Shell Assembly of the MK 48 heavyweight torpedo.
Manufacturers are accelerating use of Internet of Things (IoT) technology, according to a survey of 66 companies.
Keeping products clean is becoming a more significant part of manufacturing as standards for cleanliness, deburring, and finish grow more stringent.
One of the most cost-effective ways to obtain the benefits of automation is by adding a bar feeder to a CNC lathe or other bar machine. Costing anywhere from about $10,000 to $40,000 depending on configuration, the devices can add hours of untended operating time for part volumes of a few hundred to tens of thousands.
Shop efficiencies start with the machine tool controller, as today’s CNC equipment offers machine operators myriad tools for improving part surface finishes, allocating machine time, and cutting job cycle times.
For years, the manufacturing industry has debated the pros and cons of opening up manufacturing networks, but concerns over virus vulnerabilities and the stability of PCs on the network largely limited open-architecture PC controls’ progress and kept entrenched proprietary systems in place.
Workholding techniques using a magnetic field, a vacuum, or an adhesive can be effective alternatives to clamps. When these techniques are used, more part area is available for the cutting tools, thin parts can be held, and initial setup can be fast and simple. Plus, there is a potential for smoother surfaces and a shorter overall production cycle.
A key success factor for Industry 4.0 and IIoT (Industrial Internet of Things) initiatives is the emergence of more and better sensors in machining centers, and even in the cutting tools themselves. These sensors provide the data and connectivity that are the foundation for the “factory of the future.”
