Cutting Tool Geometry Chart: 0.academia-photos.com/attachm...
G'day everyone,
I've recently bought some new HSS tool blanks for the lathe. My intention is to grind them into lathe tools for various types of cuts and materials. Since I was already going to grind the tools, I thought it might be useful to film the process of how I decide how to grind the tools for different types of turning operations and materials.
In this video I will go over some basic tool geometries (rake angles and clearance angles) and tool shapes that I have ground over the past 6 years. This video is intended as a beginning introduction to tool grinding and will allow beginners to understand the reasons why tools are shaped the way they are. I will be using by bench grinder to grind the tools into shape.
I hope you enjoy the video, cheers.
