Another major challenge of this project was that the lathe needed to be relatively precise and accurate so that the final parts could actually be used on our robots. 33,4 тыс. подписчиков.

We have created the approach angle, the front clearance angle, the front relief angle, and the approach relief angle, all with two simple grinding operations and without understanding what all those words mean.

The last two angles we need are the side and back rakes. Since this is a right-hand turning tool, the cutting edge is on the right when the tip is facing you.
