For engineers who already know the math—but still lose projects. For the last few years, I’ve been sharing technical guides here on Mechanical Design Handbook —how to size a motor, how to calculate fits, and (as you recently read) how to choose between timing belts and ball screws. But after 25 years in industrial automation, I realized something uncomfortable: Projects rarely fail because the math was wrong. They fail because: The client changed the scope three times in one week. A critical vendor lied about a shipping date (and no one verified it). The installation technician couldn’t fit a wrench into the gap we designed. University taught us the physics. It didn’t teach us the reality. That gap is why I wrote my new book, The Sheet Mechanic . This is not a textbook. It is a field manual for the messy, political, and chaotic space between the CAD model and the factory floor. It captures the systems I’ve used to survive industrial projec...
You can design the mechanism . This is the other half of the machine: the sensing, the logic, the wire, and the safety case that decides whether your motion ever runs. If you specify machines, judge quotations, or lead the people who build them, and your training was mechanical, this is the ground you are missing. What follows is the big picture first, then the detail. Where a topic has real depth, it sits behind a deep dive toggle you can open or skip. Every number here is attributed, and where a standard is paywalled or a figure is vendor specific, that is said rather than hidden. What this covers The big picture: one loop, repeated fast Sensing and IO: digital, analog, remote, IO-Link Relays and the PLC: what each is still for Industrial networks: EtherNet/IP, PROFINET, EtherCAT, CC-Link, Modbus Drives and motion: VFD, servo, stepper, electronic cam Machine safety: stop categories, PL and SIL, safety over a network What the specificat...
