Some machine tools are modified so much and so frequently it becomes a common practice. That's certainly the case with rotary transfer machines.

Sawing is one of the most common manufacturing processes in a machine shop. It is versatile, simple and reliable. Nonetheless, many young engineers and machinists are quite familiar with lasers and abrasive waterjets but have no knowledge of sawing.

When it comes to selecting toolholders for drills, taps, endmills, shell mills and other round cutting tools, there is virtually an unlimited number of options. So how do you determine when a custom toolholder is a better option than 'stacking' standard ones?

Every so often a job or part geometry comes along where it would be helpful to have a few extra inches in a machine's work envelope, or perhaps a little higher rpm or an additional spindle. At these and certain other times, it might be worth considering a custom machine.

Abrasive waterjet systems have always provided some advantages for parts manufacturers. For one, the high-pressure stream of water and abrasive grit, usually garnet, that is delivered to the workpiece surface can cut through pretty much any material. For another, being a cold process, abrasive waterjetting (AWJ) doesn't create a heat-affected zone.

Resharpening dull taps by hand is probably not a good idea when you could be making parts. Plus, a thorough reconditioning requires a grinder designed for grinding the actual tap form. So resharpening dull taps is one job best left to the experts.

Deciding whether to use a turret or gang tooling is one of many topics that seems to engender religious fervor from one side to the other. Let's start by providing a brief overview of each approach and then dive into the details.

Machine tools are heavy. Moving them yourself can be dangerous, causing damage to people and machinery alike. But with the right tools, knowledge of how to use them and some common sense, DIY machine moving is possible—though not always recommended.

Whether an application involves simultaneous 5-axis machining or five-sided (3+2) machining, the workholders and fixturing techniques from the 3-axis world typically won't apply, according to John Zaya, workholding product manager for BIG KAISER Precision Tooling Inc., Hoffman Estates, Ill.

Koenigsegg, the Swedish manufacturer of high-end, high-performance sports cars, was featured in the 2016 documentary "APEX: The Story of the Hypercar," which describes the battle for a new class of high-speed, fast-pickup sport scars.

Industrial waste, its impact on the environment and regulation by governments have become significant areas of interest for medium and large manufacturing companies. One company's proactive approach to environmental sustainability also reveals ways to reduce waste.
