The bar feeder is perhaps the most widely used piece of automation in the metalworking industry. It has been around so long most don’t even consider it automation, especially in a world of robots, pallet shuttles and other more dramatic material handling devices.

However, the bar feeder is a critical, foundational accessory for turning operations of all stripes. The bar feeder continues to be developed and increasingly needs to be matched to an application to provide optimum efficiency.

As part of a wave of manufacturing professionals who are spreading positive messages about the industry’s technology-driven culture and career tracks, Terry M. Iverson, president/CEO of Iverson & Co. (a machine tool distributorship and rebuilder in Des Plaines, Illinois), is sharing his message supporting U.S. manufacturing by authoring his first book. In “Finding America’s Greatest Champion: Building Prosperity through Manufacturing, Mentoring and the Awesome Responsibility of Parenting,” Terry examines changing perceptions on topics such as how people view the art of manufacturing, view the return on the prototypical college education and contend with student loan debt. He also explores the importance of mentoring young people to become the next generation to strengthen America’s manufacturing industry.

While spending a year researching and writing his book, Terry interviewed more than 40 professionals, including elite athletes, executives, parents, clergy, media personalities and leaders in manufacturing, education and politics. Throughout the book, these professionals contribute their thoughts on topics such as mentorship, parenting and the importance of manufacturing in the U.S.

Machinists needing to produce parts with threads have many options for how to perform this operation. One of the most efficient processes is thread whirling, in which a circular toolholder with indexable insert cutters is mounted on an attachment that is canted to create the thread’s pitch. The blank is extended through the spindle or guide bushing, rotating at a low rpm. The cutting tool rotates around the blank, with each insert in turn cutting the thread into the blank.

The article “Two New Twists on Thread Whirling” takes a look at thread whirling and describes two variations on the process that promise to make it even more efficient. Horn’s “Turbowhirling” concept uses roughing and finishing inserts in the toolholder. The two types of inserts are specially designed to perform each task, improving tool life.

She installed a computerized system to track inventory, which in turn, has lowered inventory costs and increased inventory turnover ratio while still maintaining the necessary levels to keep customers satisfied.

Kelly began her career at Orrco in 2014 as its controller after working for a large chemical company. Her initial job assignments at Orrco were to assume the duties of the purchasing manager, to update the CAD system and to draw tooling prints.
