Advances in 3D printing are impacting the factory floor and production workflows from the design engineer to the floor technician. One area in particular is the efficient production of reliable, production-ready jigs and fixtures.

Join Modern Machine Shop, Additive Manufacturing and FormLabs Application Engineer Andrew Edman to learn how companies leverage low-cost, high-resolution desktop 3D printers and advanced 3D-printing materials to produce jigs and fixtures in house, shortening supply chains and bringing innovation closer to the production floor.

In just five years since Don Dumoulin purchased Precise Tooling Solutions, the company has purchased a five-axis machine that has opened new contract-job opportunities, and its production mix is now more varied due to extra capacity. Revenue lost to scrap and rework dropped from $225,000 in 2014 to $40,000 last year.

While Mr. Dumoulin admits that the transition has not always been comfortable, he was able to accomplish these feats without changing the fundamentals of how machining has been done at the company for the past four decades. What has changed is the company’s approach to strategic decision-making. To gather information for these decisions, Mr. Dumoulin invested in the E2 Shop System enterprise resource planning (ERP) system from Shoptech Software. Read more from the May issue cover story.

Steps For Getting Form Measurements Right

Form systems are becoming standard tools on the shop floor as their cost decreases. Instead of being operated by a typical quality specialist, these systems are more likely to be used by a machine tool operator. As such, the user may not thoroughly understand part form as it relates to the part’s application or the manufacturing process.

While today’s most basic form-measuring systems are greatly simplified operationally and much more powerful than they were just a decade ago, form measurement is still a complex process. As a result, operators should have a good understanding of the meaning of the parameters they are measuring and be familiar with how they relate to the parts being manufactured. It is critical for the operator to know how to properly set up the form-measuring system and the part for the various form functions that are available.

After the Build Is Done Why Do the Bills Keep Coming?

A metal additive manufacturing (AM) part is essentially “welded” to the build plate, and you will not be able to pull it off without some assistance. Even then, the AM part will need post processing before it is ready to use. Here are some costs associated with post processing AM parts.

Powder Removal: AM parts build “down” in a powder-bed fusion system as new layers are added to the top, which means that parts are buried in powder when they are done (see Figure 1). After the build has finished and the parts/build plate have cooled, the machine operator has to remove all of the powder from the build volume and sieve/filter/recycle it for later use, assuming you want to reuse it. This is not an expensive step, but it does take time.
