Titanium Impeller, Blade expert

[declfc]

Hi, ive got a new project to get my teeth into.

As the title says its a Titanium Impeller. I have programmed plenty of jobs out of Titanium and I have also programmed a few Impellers, but they have all been out of Ally. I know this is a bit specialist, but if anyone has done this before any tips would be more than welcome.

I will be programming the Impeller using Mastercam X6 Blade expert. I like this, does most of the hard work for me! buts its the speeds/feeds, cut depths, roughing startagies ect. im experimenting with at the moment. I just dont want to go breaking too many cutters as the coated Taper mills im using arnt cheap!

Also would love to have a chat with some fellow blade expert Impeller programmers to swap tips and any info we can share.

 

Impeller details:-

 

Material - Titanium TA11

 

Hub is 120mm at the bottom, up to 30mm at the top.

42mm in height.

7 blades with splitters, so 14 in total. Not too tight.

 

When I make ally ones I use a 4-6mm 3 flute to very quickly remove most of the material around the blades and splitters, (surface high speed, OptiRest)

 

I thinking I will be using soild carbide tapermills (TIALAN-T21 coated) to do most of the work on this one.

 

Thanks for looking, keep up the good work.

I have not machined any impellars yet, but intend to , we had a study completed by Sandvik, for a titanium impellar, i have attached if this is of any use ?

Thankyou, The info here is brilliant, just the sort of thing im looking for. Do you know what sort of depth of cut was planned for for the 10mm and 8mm ballnose cutters.

Unfortunately no, but i think this info is available somewhere on the Sandvik website, i am sure i have seen an actual cutting data sheet, i will look and post if i find it
