    Ok this does have a bearing on the design so please be patient with me, If you were machining these Z parts what would your Cutter preferences be and why, this will help me when i finalise the design, so please everybody pipe in, Remember What type and Why please, if you prefer then PM me as i know some of you wizards like to keep your advantage secret, but please let me know. Right off to bed now 4 hrs should do LOL speak after 1..

    Depends on what you want and if your lazy.?

    Could get away with doing the whole lot with 6mm and no tool changes but would take longer due having to keep shallower depth of cut for 6mm cutter with 30mm plus flute length.?

    Or could use 10mm that would allow to hog the whole lot away quickly with deeper DOC and just have larger radius in the corners.

    Or if really need tight corners use combination of both 6 & 10mm. Use large cutter to Hog the 98% material away then run round twice with 6mm. One profile pass to fettle corners then another full depth to clean up.

    If the radius doesn't matter, which in your case don't think it does then I'd use 8 or 10mm has they will allow more DOC and speed up the Job with no tool changes. . . 8mm would be my preference.!

    I'd use 8mm 2fl to cut the pockets, do finishing passes on the pockets with 6mm 1fl if required and cut the part out with 6mm. So basically the same as Jazz.

    OK gents I will run that through a V-carve simulation with an 8mm cutter (two flute) and see what i get and if any alterations will be required to take into consideration the radiuses, although i Know i wont be doing the job myself it will give me an idea of what the finished part will look like..

    Ok Ive altered the design to put in some registers (In Red) and opened the channel to allow for a standard 1605 ballnut bearing seats are all now standard as well Im going to transfer this lot to V0Carve and run the simulation to see if i get any surprises. All the bearing and ballnut mounts are now seperate and adjustable, there is ample access for Lubrication as well

    You can only see one side of the registers but take my word for it they are there..

    Rick simple thing but worth doing is putting the register on the first pic at the top not bottom it makes setup easier has the register sits on the bearings machined edge while bolting up.

    Ahhhh cheers Jazz, I had to read that twice LOL yeh makes sence now, Thats wont take two ticks as the bearings are 46 wide and the pockets were 48 so ive just moved 1 wall in 1 mm so ill move that back out and the other one in, that will still give me 1 mm free play in the pocket.
