I recently had the chance to work with TechSolve, the machining consulting firm based in Cincinnati, Ohio, on filming some really ugly machining passes.

The point was cutting force analysis. Watching poorly performing cuts while also seeing the corresponding cutting force profiles illustrates what force measurement can reveal about the process. In many cases, force monitoring is limited to the machine’s spindle-load monitor, but TechSolve can bring more than this. It can measure forces more specifically and directly using a three-component dynamometer.

These days, most CNC turning centers use live centers in their tailstocks to provide support for long parts. Unlike a dead center that does not rotate, a live center features a bearing assembly to enable its tip to rotate with the part so there is much less friction between the tip and the part. As a result, higher rotational speeds and faster turning operations can be achieved. That said, not all live centers are the same and some designs differ depending on the application, as I learned from Tom Sheridan, vice president of marketing for Royal Products.

According to Mr. Sheridan, the company’s decades-long experience manufacturing live centers led it to develop the Roto-Shield coolant-production system, which uses a spring-loaded seal to keep cutting fluids out of centers’ bearing assemblies and increase the centers’ lives. The centers feature points with comparatively short lengths and thick girths for increased rigidity, and the robust bearing assemblies are designed to provide stability while maintaining high speeds. 

I have but one small criticism of Scott Walker’s new book, which is a collection of selected newsletters written for the staff of Mitsui Seiki USA, the U.S. sales arm of Mitsui Seiki, a machine tool builder in Japan best known for large, high-torque five-axis machines for titanium aerospace work. As president of the U.S. company from 1999 to mid-2018 when he became chairman, Scott distributed these newsletters to staffers with their bimonthly paycheck. My criticism is this: Instead of titling his book “Rantings of a Machine Tool Salesman,” he should have called it “Teachings of a Machine Tool Salesman.”

Angry people rant, often with more emotion than reason, whereas thoughtful people who care seek to teach, to enrich, to edify. Reading even a few of the newsletters in this book shows that the authors (Scott penned most of the newsletters, but a few were contributed by his associates) clearly intended to teach—to convey insight, knowledge and perhaps most of all, wisdom. I’ve been sampling the newsletters in this book (there are 216 altogether) in the past few weeks and I can say that I learned many things about the inside workings of a machine-tool sales organization, the ups and downs of selling high-ticket machine tools, the intricacies of dealing with a Japanese parent company, the challenges of managing a small team of dedicated staff members and more.

The image gallery above, based on Modern Machine Shop magazine’s Modern Equipment Review Spotlight, features a variety of equipment and software related to measurement and inspection from Beta LaserMike, Alicona, DWFritz, Zeiss, Creaform and MC Machinery Systems. Several of these technologies were displayed at IMTS 2018 last month.

Six Points on Effective Leadership

Thousands of books and articles have been written about leadership claiming to deliver useful information about what it takes to lead others to a desired outcome. John C. Maxwell is probably one of the most accomplished authors on the topic, having written such best-selling books as “Leadership 101” and “The 21 Irrefutable Laws of Leadership.” Any publication can describe the basics of leadership, and many even share examples of how people have led others to achieve great things. However, anyone faced with the need to lead must ultimately develop their own leadership style—one that will allow them to achieve their own desired outcomes. The following points should be considered as you develop your personal leadership style.
