Stephanie (Monsanty) Hendrixson served as a Modern Machine Shop summer intern in 2012 and joined the team as an assistant editor later that fall. She currently works on event news for MMS Online and on the production of the print magazine. She also blogs about additive technology and helps to manage Additive Manufacturing magazine as its associate editor. Stephanie holds an M.A. in professional writing from the University of Cincinnati and a B.A. in English literature and history from the University of Mount Union.

While micromachining is not a specific type of machining process or strategy, it often demands specialized equipment and tooling. Micro milling and drilling requires tiny tools as well as a machine with the spindle speed to cut effectively with them (as this manufacturer and shop owner learned). As another example, it’s possible to cut micro features with abrasive waterjet, but the nozzle orifice, mixing tube and abrasive particles must be downsized appropriately.

The 2015 World Machine Tool Output & Consumption Survey (the basis for May’s cover story and artwork seen above) indicated that U.S. machine tool consumption surpassed $8 billion in 2014, a significant capital investment driven in part by low interest rates. For a complete overview of the data and what it means for manufacturers worldwide, find the story and an infographic on page 72 of the digital edition.

Did you or one of your kids ever play with one of those pin impression boards? The idea was that you could press any object—a smaller toy or a hand, for instance—gently into the pins on the back of the board and see a crude relief image on the other side.
A clamping element from Euro-Tech called “The Jaw” (pictured above) works in a very similar fashion. The product has a number of hydraulic pins on each side that quickly conform to the shape of any part placed between them. Internal clamping sleeves lock the pins in place, and the company says that the form fit reduces required clamping force. The adaptable system can be used as jaws for vises, as supports, and in combination with robot grippers and other custom solutions.
A lathe or multitasking center equipped with both a main spindle and subspindle enables turned parts to be machined on both ends in one setup, by simply passing the bar from one spindle to the other. But what if you don’t have a subspindle? A robot flipping system can be a cost-effective automated solution.
The video above from Methods Machine Tools shows a Nakamura AS-200 multitasking machine equipped with a FANUC LR Mate 200iD7L robotic arm with two sets of grippers. Around 3:06 in the video, the robot removes the first workpiece, swaps in a blank, then sets the first workpiece unmachined-side down on a shelf just to the left of the machine door. The robot then grasps the part from underneath, flipping it over to be placed back in the spindle for machining on the other end. The configuration enables a two-spindle process to be completed with just one spindle on a smaller machine.

The motorcycle part manufacturer featured in the cover story of Modern Machine Shop’s April issue struggled to keep up with the cyclical demand for its products—until it added the robot-tended cell visible in the cover image. Another shop featured in this issue shares its experience moving from manual to automatic pallet-switching and a third was able to reduce machine run time with an automated five-axis cell, additional examples of automation used to reduce setup time and streamline operations.
