Johnny Freeze to Present at PMTS Knowledge Center


Coming in April to the Precision Machining Technology Show (PMTS), presentations from industry experts will be part of festivities through knowledge centers, which will be located in the back on Hall D. Johnny Freeze, applications engineer, Peterson Tool Co., will be presenting “You Cannot do that on a CNC … Or can You?” on Wednesday, April 22, at 10 a.m.

Johnny will explain how CNCs can be even more efficient with simplified setups that are incredibly user/operator friendly.

The knowledge centers will be held on the show floor and are accessible to all attendees. But you must be at PMTS in Columbus, Ohio. Click here to learn more and register.

Presentations Shine at PMPA Management Update

This year's Management Update was held in San Antonio.

At the end of February, the PMPA (Precision Machined Products Association) featured its Management Update conference in San Antonio, Texas. Just a couple hundred yards from the Alamo, the hotel offered nice accommodations for an event that included great networking opportunities and an outstanding lineup of speakers.

After a welcome reception on the evening of February 26, the conference sessions opened the next morning with a very positive economic analysis by Brian Beaulieu, CEO of ITR Economics. He foresees strong production numbers for the remainder of the year, with positive trends continuing through 2017.

Other large-group sessions included presentations with deep management insights from Richard Sheridan, CEO of Menlo Innovations, David Marquet, retired naval officer and author of Turn the Ship Around!, and growth expert Mike Machalowicz, who associates business growth with the methodology of growing colossal pumpkins.

Afternoon breakout sessions consisted of a series of speakers who addressed such topics as the skilled labor shortage, disaster preparedness, social media marketing, health care costs, and creative leadership.

Typical of PMPA conferences, this year’s Management Update addressed its audience with highly appropriate content to help attendees improve their businesses. These events are well attended for good reason. For more information about upcoming PMPA events, including the National Technical Conference to be held immediately preceding PMTS, visit the association's calendar page.

Chemistry Determines Machinability

Manganese and sulfur have a powerful effect in reducing flank wear on HSS tools.

Manganese sulfides are a separate internal phase.

Flank wear is the “normal” failure mode for tools when machining steels. The volume fraction of manganese sulfides is a determinant of the tool’s wear rate. “The wear rate of high speed steel tools decreases rapidly up to about 1 percent volume fraction of MnS and then levels off to a constant wear rate as the volume fraction is increased.“-Roger Joseph and V.A. Tipnis, “The Influence of Non-Metallic Inclusions on the Machinability of Free-Machining Steels.”

As sulfur rises beyond 1% volume fraction, surface finish improves, chips formed are smaller with less radius of curvature, and the friction force between cutting tool and chip decreases because of lower contact area.

How does manganese sulfide improve the machinability? The MnS inclusions act as “stress raisers” in the shear zone to initiate microcracks that subsequently lead to fracture of the chip. MnS inclusions also deposit on the wear surfaces of the cutting tool as “built-up edge (BUE).”

BUE reduces friction between the tool and the material being machined. This contributes to lower cutting temperatures. BUE mechanically separates or insulates the tool edge from contact with work material and resulting heat transfer. This is why resulfurized steels in the 11XX and 12XX series can be cut at much higher surface footage than steels with lower manganese and sulfur contents.

'Easy Button' Made Easier for Mfg Day

Across North America, 360,000 people attended the 2014 Manufacturing Day event.

The partners responsible for Manufacturing Day have refreshed its website,, to make it easier for sponsors, companies, supporters and volunteers to participate in this year’s event. It is scheduled for October 2 this year, but it is not too early to think about getting involved, and this website is an entry point.

For 3 years, Manufacturing Day has celebrated the world of modern manufacturing as a direct means of inspiring the next generation of manufacturers across North America. It is manufacturing’s pro-active approach to show and tell young people why modern manufacturing does not represent many of their preconceptions.

Last year, more than 1,650 companies, educational institutions and associations in all 50 states, Canada and Puerto Rico participated in Manufacturing Day events, which were attended by 360,000 people. With the launch of this new and easier to use site, Mfg Day is hoping to increase participation and move further in the important work of educating the public about the benefits of careers in modern manufacturing.

It’s a concerted effort to answer one of manufacturing’s most pressing problems. Seems like a no-brainer to me. Click here to access
