Chris Koepfer has been involved in metalworking for 30 years. His first 14 were in the machine tool group at Cincinnati Milacron where he honed his technical writing skills in turning, machining and grinding before joining Modern Machine Shop in 1992 as an associate editor. In 2001, he helped found MMS’ sister publication Production Machining, which speaks to the precision machined parts segment of the industry. Chris is graduate of Xavier University in Cincinnati, as are three of his four children, and an XU basketball fan—which can be as daunting as working in metalworking, he says.

Mastercam Sails with America’s Cup

Mastercam is being used to help produce a racing yacht for the 2017 America’s cup

CNC Software, developer of Mastercam software, is part of the development team for Oracle Team USA, which is a participant in the 35th America’s Cup being held in Bermuda in 2017. Oracle Team USA is defending champion of the America’s Cup.

Mastercam software is being used by Core Builders Composites (CBC), which produces the carbon fiber components used in the construction of the Oracle Team USA’s racing yachts. The company has built all of the team’s yachts, including the trimaran that won the 34th America’s Cup.

Part designs originate with the Oracle team and are sent to CBC for production. Mastercam software is the bridge between the CAD file and the CNC machine tool, creating the necessary tool path to produce the part. These parts are produced by CBC on a five-axis machining center with a workpiece capacity of 59 ft. by 20 ft. by 10 ft.

A Smart Path to Reshoring


To keep pace with its growing business, Hybrid Racing (Baton Rouge, Louisiana) needed a smarter way to manage its supply chain. After failing to find reliable domestic suppliers, the company outsourced its production to China.

The pitfalls of such a move are well known, especially with a growing and rapidly changing manufacturing business. William Davidson, founder and CEO, describes them as communication, cash flow and lead times.

In 2015, with business booming, Hybrid was reluctantly planning to send more work to China when the company stumbled across MakeTime. This relatively new company, based in Lexington, Kentucky, features an on-demand virtual machining platform designed to help companies such as Hybrid better control their supply chain by enabling the use of domestically sourced manufacturing.

In a nutshell, MakeTime offers buyers instant access to a network of thousands of prequalified suppliers with production hours available on their CNC machines. This allows companies like Hybrid to overcome production shortages, eliminate risk in the supply chain and rest easy with guaranteed lead time and quality.

One Year to Go


No matter how one slices the calendar—days, weeks or months—it all adds up to the fact that The Precision Machining Technology Show (PMTS) is only a single year away. The 2017 edition runs from April 25 to 27, 2017, and will occupy the Columbus Convention Center in the heart of the city’s entertainment district.

Since its inception in 2001, the PMTS has grown and continues to grow. Its target audience is the precision machined parts industry, and after a record setting show in 2015, it is already on target to be even better.

A year goes by fast. Therefore, it's not too soon to begin making plans to attend PMTS 2017. Go to to learn more about the products, services, process innovations and players in our industry segment. Time is ticking.
