Comparative study of the usage of SAE 8620 and EN 36C in an automotive...
An automotive differential gearbox is a critical component of the powertrain involved in the transmission of power and its appropriate distribution to the wheels....
Case study: Heading to the High Torque© finish line
More than most industries, today’s aerospace, defense, and automotive-component manufacturing is challenged with machining a lot of exotic alloys and hard metals. This can...
Service life of cylindrical and bevel gears under variable load and stresses
Transmissions are usually loaded by variable external loads under real operating conditions. The decisive load for a gearbox is in most cases the applied...
Comparison of strength ratings of plastic gears by VDI 2736 and JIS B 1759
The demand for strength ratings for plastic gears has been consistently increasing. However, there are no international standards such as ISO, DIN, or AGMA,...
Women in manufacturing: Diversifying the industry
You don’t have to go very far back in time to find a point where the role of women in the manufacturing sector was...
Latest advances in chamfer hobbing
While not considered a “value adding” process such as hobbing and fine finishing, cylindrical gear chamfering and deburring are getting the recognition they have...

Detecting cracks in PM green products using laser vibrometry
Cracking of green parts in powder metallurgy (PM) is a big concern in the PM industry. Detection of cracks in green parts before sintering...
Metallic glass gears up for ‘cobots,’ coatings, and more
Where are the robot assistants we were promised?
For all the space that robots have occupied in the popular imagination for the last hundred...
Formulating load-sharing behavior in epicyclic gears for wind turbines
In an ideal epicyclic gear set, every parallel gear path transmits the same amount of torque. However, it is well known that certain manufacturing...
Specifying surface texture parameters – tricks and techniques
There are many different ways that designers specify surface texture parameters for their parts. Some specifications are good, some not so good. Some are...
Design of a double spiral bevel gearset
It is known that bevel gears are used to transmit rotary motion and torque between intersected axes in case there is no possibility of...
The advantages of pulse plasma nitriding
In the gear manufacturing industry, when case-hardening, tempering, or nitriding the surface of steel, whether for gears or gearboxes, the options have traditionally included...
Incorporating 3D artificial intelligence with AR and VR technology
