Machine Technology: No-hands tool changing
When CNC milling machines were conceived some in the metalworking industry asked why a computer couldn't also manage tool changes. That question was the impetus behind the development of the automatic toolchanger.
Manager’s Desk: Shop owner deals with theft
Keith Jennings, who writes the Manager's Desk column for Cutting Tool Engineering, never experienced being sad and mad at the same time until recently, according to his September column. The cause? A trusted employee who wasn't so trustworthy.
Taking measures to improve metrology
Many — if not most — shops encourage employees to purchase their own measurement tools. Some even help by "financing" these purchases, allowing machinists to pay them off in small increments. And what machinist doesn't want his or her "own stuff" with which to do the job? But does allowing machinists to use their own measuring tools actually make sense?
Three steps to optimizing machining
To profitably machine high-quality parts, many manufacturers follow a similar path, beginning with tool selection and application and then solving any problems that arise in a reactive way. However, research suggests that manufacturers should examine the entire machining process before cutting begins, focusing on eliminating rejected parts and unforeseen downtime.
No-cost thread mill program generators
Numerous toolmakers provide free programs that will automatically generate G code for a specific thread milling application. The programs vary in sophistication and in whether they are online-only or downloadable, but all are useful tools. Among the suppliers of these apps are Scientific Cutting Tools Inc., Simi Valley, Calif.; Guhring Inc., Brookfield, Wis.; and Kennametal Inc., Pittsburgh.
How to keep from scrapping parts
Scrap happens. By scrap, I mean parts that are out of tolerance and, therefore, useless. Unlike other by-products of the manufacturing process, such as chips, shavings and drops, you generate scrap only through mistakes. nnSo the challenge of reducing scrap comes down to preventing mistakes.
Swarf is telling you something
Swarf, which is the result of particles being removed when grinding hard or difficult-to-machine materials, tells a story.
3D-printed bone drill improves surgeries
Metal laser melting has made possible a number of groundbreaking developments in the medical field. One example is a 3D-printed bone drill that, unlike some traditionally manufactured drills, is designed not to damage tissue during surgery.
Lead Angle: Targeting markets high and low
The boost in productivity that the latest cutting tools provide enables manufacturers to reduce the amount fracking companies pay for parts.
Rush Machinery and Grinding Doc collaboration
For the 83rd episode of Cutting Tool Engineering’s Grinding Doc video series, Dr. Jeffrey Badger visits with Rush Machinery in Rushville, N.Y., to begin a three-part series devoted to establishing scientific truing parameters.
Pratt & Whitney adds new fan blade manufacturing facility to Lansing plant
Pratt & Whitney's new 93,000 square-foot facility adds to an already existing GTF fan blade production line in Lansing. The company's AutoAir facility has had a tenfold ramp-up in the past 20 months, and has increased its workforce from just over 200 to almost 700.
2017 U.S. cutting tool consumption up 7.1%
July U.S. cutting tool consumption totaled $170.95 million according to the U.S. Cutting Tool Institute (USCTI) and AMT – The Association For Manufacturing Technology. This total, as reported by companies participating in the Cutting Tool Market Report (CTMR) collaboration, was down 8.4% from June's $186.57 million and up 16.0% when compared with the total of $147.43 million reported for July 2016.
