If by "new machinist," you mean you have very little experience turning metal and grinding tools, I would sugfgest getting a few pre-ground tools and attempting to grind others to match.
I see that you are in the UK, so I don't know if there is a similar option, but LittleMachineShop here in the USA sells a set of ground tools and some blanks for just such practice:
Turning Tools 4516 Six presharpened 1/4" high speed steel tool bits; Five unsharpened 1/4" tool bits; Sharpening instructions; Learn how to grind tool...
Otherwise, you can follow some of the instructions posted online or videos on YouTube. You will find what works for YOU with some practice, which may actually differ from some of the things on your chart a little bit.
If you search for "grinding toolbits" on YouTube, you will find lots of instructions by lots of different posters, with some periferal information as well.
Of course, I am assuming that you have a good grinder, a grinding wheel dresser, and a bench stone.
Sorry if I'm assuming too much in posting this. No ill will intended.
