Hi. Heres my work

[magicniner]

Lovely, a hint as to how you arrived at those results would be most informative ;-)

Sorry i dont get what you mean?

[magicniner]

I meant what CAD, CAM and machinery did you use?
Did you do all the CAD modelling, all the CAM and run the machine yourself?
Was the job run in your shed or at work?
What speed and feed calculators do you use, what cutters did you use.
We can assume answers but we'd probably be wrong :D

I did the job start to finish using some edgecam and some online programming.
Using 3 axis hardinge 1000 at work.
It was a big lump! Over 100mm thick so took a while to get it cut out.
I used about 30 different types of tools for this job.
I use feeds and speeds i have learnt from experience and up to 6000rpm.
Supporting it wasnt easy and i bolted it to some paralells from undernearth.
Took me 55 hours.

That's impressive, I don't think I have 30 different types of tool, not even sure I can think of 30 different types of tool for use in a milling machine ;-)

From memory i used 80mm face tool and long series drills to create a way to mount to paralells.
Then a long 10mm 3 flute to cut off excess material.
Then roughed out with 80 and 50 facemills.
Then various sized end mills and ballnose to achieve shapes. Then many different drills and taps and finally long series tools to do the top angled fine pitch sensor hole.
The item was for atomic testing agency
