Not all threaded connections serve similar purposes.The load-carrying needs of an aerospace engine support bolt in a tension assembly greatly exceed those of a simple screw that fastens a cover plate to an electrical wall socket. International thread-acceptance documents and standards recognize this basic engineering fact, and incorporate different thread-inspection requirements into their verification standards.

Machining composites presents unique challenges compared to metals. Reinforcement fibers are abrasive, shortening tool life. The plastic matrix carries away little heat, unlike metal chips, and overheating can melt the matrix.

The cost benefits of deploying multitask machine tools are undeniable, with multitask machines offering the ability to perform many machining operations on parts with just a single setup.

Highly realistic 3-D simulation software can greatly improve manufacturing processes, lending sophisticated visualization tools that help increase manufacturing productivity and product quality.

Process improvement encompasses a wide range of tools, techniques and strategies. When properly deployed, shop-floor data collection and monitoring systems can help factory-floor managers leverage key data metrics including overall equipment effectiveness (OEE) and total effective equipment performance (TEEP) that measure machine uptime and pinpoint bottlenecks or other problems in order to improve machining performance.

Once considered also-rans behind automated drilling and filling, alternative aerospace automation processes, like painting, coating, sanding and other surface preparation, are starting to catch on with aerospace builders, especially in commercial aviation where immense order backlogs loom large and demand immediate attention.

Interesting changes have been happening at Haas Automation, one of the few American machine tool builders left standing after scores have been displaced over the decades by Japanese, German and Korean builders.

As automotive manufacturers around the world begin to invest in products and components made with a variety of advanced lightweight materials, the ComauFlex body shop solution—developed and refined over the past decade—has been demonstrating how it can accommodate dissimilar materials while incorporating a wide range of processes.

What are companies looking for in manufacturing execution systems [MES] software?

Additive manufacturing needs to improve its quality and consistency as it assumes a bigger role in manufacturing, advocates of the technology say.
