Last year, Hot Wheels celebrated its 50th anniversary. While a writing gig in manufacturing and engineering probably sounded surreal to the 8-year-old version of this author, truth be told, he was obsessed with Hot Wheels and Matchbox toys for most of his childhood. Somewhere in a box in the basement there’s a 1967 Camaro and a 1953 Corvette that would still bring a smile to this face.

The Past, Present and Future of Vehicle Electrification

Question: I am a gear engineer for a motor manufacturer in China. I am writing about noise generated from cross-helical gear assembly error. I want to learn the relationship between the misalignment (center distance change and cross-angle shift) and transmission error. It is better under the loading and theory conditions. What is the trend of cross-helical gear development (use ZI worm and involute helical gear, point contact)?

Workholding Systems Continue to Focus on Speed and Efficiency to Improve Machining Operations

As most of you know by now, the trade show formerly known as Gear Expo is now the Motion + Power Technology Expo. If you're a gear-industry veteran, you might be confused by this change. If you've been coming to the show for years - or exhibiting at it - you might even feel a little betrayed. But I'm here to tell you it's going to be alright.

We’ll get back to our “origin story” project soon. One thing I have noticed about the guest blogs so far is that the people kept moving up the ladd...

My dear friend Octave’s account of his co-op experience (see Tuesday’s 1-29 post) reinforces my belief that no one should trust an engineer or desi...

Here is the first of our guest blogs on the topic of how you entered the gear trade. Chris Trochelman (pictured above, fa...

Contrary to what appears to be popular belief, 5-axis CNC gear manufacturing is not limited to milling with end mill, ball mill or CoSIMT (Conical Side Milling Tool — it is the generic form of the Sandvik InvoMill and Gleason UpGear tools.) tools, where throughput is too low to prevent production at any significant level. Straight and spiral bevel gear manufacturing on 5-axis CNC machines using face mill cutters provides essentially the same throughput as conventional gear cutting machines — with added benefits.
