Half of Mr. Jari Piili’s daily working time is spent at the computer – programming and designing 3D models. So is he a software developer? No, he’s a machinist specially trained for his job by his employer, ATA Gears, designer and manufacturer of world-famous bevel gears. A machinist’s job is not dirty work requiring brute force. No way: It needs good spatial perception, because a bevel gear with its curved facets and concavity, convexity and sphericity can be challenging when modelling the clearance between tooth contact points.
”In a machinist’s job, you can never be too accurate,” Jari says. ”You need to recheck and double-check and learn and maintain your own meticulous routine and process. You can definitely be proud of your work, of being a member of a rare profession, of producing top-quality, superbly-functioning bevel and cylindrical gears.”
