Advanced manufacturing technology is no longer limited to large companies. Continuing innovations in automation, shopfloor software and more have made borne fruit with products and options well-suited and affordable for independent manufacturers. This maturation doesn’t just make these technologies accessible for job shops, however: it has started to make these technologies a necessity to compete in the modern manufacturing marketplace.

High-Mix Automation

Automation has long been out of reach for job shops for two reasons: cost and a reliance on low-mix production. Technology maturation has led to lower prices on cobots, pallet changers and other automation technologies, but high part mixes have continued to stymie lights-out automation efforts.

of Champaign, Illinois, bypasses this limitation by acknowledging that high-mix automation doesn’t need to mean full 24/7 automation. “If you’re trying to get 24/7 production, that takes a lot more planning than just trying to bump your production by 50%,” says Kurt Wagner, owner of Wagner Machine. Wagner has used cobots to automate machine tending on five-axis machines for jobs requiring at least 50 hours of total machine time. As a single-shift shop, even four hours of nightly automation is a 50% productivity boost, so time spent on programming is offset quickly enough to make automation cost-effective. By the time three of Wagner’s five planned custom cobot cells were online, robotic automation had boosted the production milling team’s productivity by more than 30% while improving on-time deliveries.

is another high-mix shop that uses automation to manage its workload. While the shop does use its palletized five-axis turn-mill for lights-out automation, the machine’s pallet changer has been just as useful for prototyping during the day. With six pallets, the shop can prepare for multiple future jobs even as the machine works on one. “It keeps us productive when we would otherwise have to stop the machine,” says Todd Peterson, co-owner of Peterson Machining.

Shopfloor Software

High-end ERP and machine monitoring software have also driven significant productivity improvements at job shops. For , adopting ProShop ERP improved setup documentation and management of job travelers. “It’s led to reduced overall setup times, higher spindle uptime and less scrap,” says Chris Guidotti, son of East Branch’s founder. Revenue increased by 18% within a year, with process improvements helping the shop eliminate $20,000 in expediting fees and $12,000 in shipping fees.

Machine monitoring has made a similarly large impact at . While the shop’s machinists were originally apprehensive about switching from paper shopfloor efficiency tracking to MachineMetrics, positioning the new machine monitoring strategy as process-based rather than people-based improved shopfloor acceptance. The ability to quantitatively track machine uptime helped AccuRounds determine where additional training or tooling adjustments were most needed. The shop’s resulting improvement efforts led to a 20% increase in OEE and a 15% reduction in tooling spend.

Cybersecurity

Cybersecurity options are now more available to job shops than ever — and more necessary. Hacking attempts on job shops are not matters of if, but when, says Allison Giddens, president of . The cost of developing a cybersecurity plan now is far less than the cost of recovering lost data (and lost customer trust) after a malicious cyberattack.

Job shops aiming to work in the defense industry should also know that Cybersecurity Maturity Model Certification (CMMC) audits will soon be a prerequisite for sensitive work. These audits will require shops to not only invest in cybersecurity technology and training, but prove their proficiency with it.
