Milling vs. Grinding for Rapid Stock Removal

A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.

Extrusion and Drawing Knowledge

Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.

Change-up Pitch: From Metal to Plastic

Even though it’s been around since the 1950s, when engineering-grade resins were first introduced, many manufacturers still are not familiar with the many benefits that metal-to-plastic conversion provides.

Mix and Match for Lightweight Autos

It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort.

Hard Hips

The challenge of machining hip replacement implants out of cobalt chrome

Nano Molding and Tooling

The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.

Dunnage: Often Ignored, Always Important

Dunnage used to ship and process automotive parts on the shop floor is a key component in the overall manufacturing process, yet it is often overlooked when companies are working to make lines lean and green. Today, it is important that manufacturers know that most dunnage used to transport parts from start to finish can be reused for the lifetime of production.

Drilling Difficult Materials

Drilling a hole to required specification in production drilling can be challenging when the workpiece material is especially difficult-to-machine.
