If you’re into CNC machining, mechanical tinkering, or just love a good engineering rabbit hole, you’re in for a treat. Substack’s [lcamtuf] has written a quick yet insightful 15-minute introduction ...

This is an idea for a computer program to convert certain sizes of involute spline shaft hobs into different sizes, and vice-versa, as they have the same circular pitch or diametral pitch (P). It is ...

Following an earlier proposal for transcribing the angle of hob profile teeth measured in inches, our correspondent now describes how to execute a similar task with metric measurements: “The U.S.

The ubiquitous ball spline. Basically, it is a type of mechanical element used in a variety of industrial applications where precise movement and alignment is required, like machine tools, robot arms ...
