Just in time (JIT) manufacturing, by nature, increases setups and shrinks batch sizes. This puts shops in a bind, because more setups and smaller batches are typically less profitable; but saying "no" to work can be even more painful. The burden to search out creative ways to reduce cycle and setup time in order to realize a profit falls to the shops that commonly perform JIT work and on the shops that can’t afford to turn it down when the opportunity arises.

Three primary elements play a heightened role when machining molds for plastic injection molding of microparts compared to moldmaking for the macro realm: part size, feature size and dimensional tolerances. 

The Look Ahead column in the April 2017 issue of Cutting Tool Engineering magazine features a project to improve robot mobility as much as humanly possible.

The Look Ahead column in the April 2017 issue of Cutting Tool Engineering magazine features a portable 5-axis machine tool made from carbon composites.

END USER: Zodiac Engineering, www.zodiaceng.com. SOLUTION PROVIDER: Brush Research Manufacturing Co. Inc., (323) 261-2193, www.brushresearch.com. CHALLENGE: Reduce programming and cycle time, and eliminate the need to regrind or replace chamfering tools when deburring part edges. SOLUTION: Apply in-line abrasive nylon disc brushes.

A shop that cylindrically grinds steel shafts is having trouble keeping up with tighter and tighter surface-finish tolerances. Though the shop can hold the finish, roundness and size take a hit. So the shop seeks the Grinding Doc's advice.

Drilling, reaming and boring are the basic holemaking operations of machining. In simple terms, drilling creates a hole in a workpiece where there was no existing hole. Reaming and boring accurately enlarge holes that already exist.

Machine tool builders, tool suppliers and software developers now deliver technology that makes it possible for CNC operators to set up jobs in minutes rather than hours, and deliver parts in days instead of weeks. 

To reduce setup—as well as overhead costs—in a job-shop environment, first examine the workholding methods, according to the Shop Operations column in the April 2017 issue of Cutting Tool Engineering magazine.

The design of the knee mill goes back to 1936, when Rudolph Bannow’s company produced a knee-and-column vertical mill with a rotating turret and sliding-ram head. The mill became known by the company’s name—Bridgeport—which, like Kleenex, became the generic signifier for mills of similar design. 

Shop Profile: MTU America machines parts for large diesel engines while helping fill the skills gap.

The April 2017 issue of Cutting Tool Engineering magazine includes an occasional column on Swiss-Style Machining that addresses training options for new and experienced machinists.

The April 2017 Machine Technology column in Cutting Tool Engineering magazine covers tabletop equipment for sharpening cutting tools.

Commit to a German-style, dual-training apprenticeship program so your shop can produce its own skilled workers, suggests the director of the German American Chamber of Commerce of the Midwest Inc.

On March 2, mHUB, a physical-product innovation center and microfactory, celebrated its official grand opening in Chicago. The center is designed to galvanize the area’s manufacturing ecosystem by generating innovative ideas, attracting world-class talent and fostering collaboration.

U.S. toolmakers should “claim the origin of [their] products,” he said during a speech at an industry event hosted by the grinding-machine and EDM builder Vollmer. Viaud-Murat pointed out, though, that manufacturers should not claim a product is U.S.-made if it isn’t. Doing so could result in legal action against the offending company, initiated by the Federal Trade Commission.

Omron Adept Technologies Inc.’s LD-series mobile robot can gather information about its surroundings and automatically generate a map with just one run through any given environment.

One roadblock for parts makers to begin implementing Industrial Internet of Things technology is psychological: Implementation sounds like a big, time-consuming undertaking. It can be, of course. But a good way to start might be to take about 20 minutes and fire up Smart Attend, an all-in-one manufacturing-facility communication system from Smart Attend Inc.
