Stefan in his Your Questions, My Answers answered my question about his slide calculator used for feeds/speeds on his milling machine.

Hoffmann/gallant 11 0965, available in En and De (I assume that means both language and metric or imperial judging by looking at the pic in their catalog).

Available locally from [email protected] on Matheson Blvd in Mississauga (distributor) for CA$24 each. 2 weeks lead time. I have one of each on order.

Hah! I just watched that episode last night. I wondered about the speeds and feed calculator too. Thanks for this :)
 
Most endmill manufacturers have calculators on their site for free based on current technology and knowledge. You will find that these far exceed what the smaller machines that most use.

For instance on my machine the limitation is horse power, rigidity in the machine. Pushing the upper limit on the machine I might reach 20% of the what a given cutter can do which in itself is surprising. What is even more surprising most of my feeds and speeds are at least 4 times what I would have done manually with better results.

For me I start off very conservative with new cutter sizes or materials and build from there.based on first cut I can usually guestimate junp required to get close, when the machine starts groning, push past or back off and hopefully hit the ideal combination.

The site Gerrit provided earlier pulls all the major companies recommendations together in one place. Pretty ambitious website. They claim to be connected to the companies and always updating the info. I like it.

I've used it too. It is good but it is generic and isn't vendor specific. I have found that there is something magic about following the vendors recommendations. I've started keeping a running list of the recommendations for each of my inserts.

HSS was so simple. It just worked. I don't know why I left the well travelled trail.......

Ain't that the truth! Some of the inserts I got lately off Amazon and Ali actually have recommendations on the box. Some of them are obviously BS!

There is no need to buy generic inserts from AliExpress.com, there are at least 2 stores that sell branded inserts. Using the codes such as VP15TF you can reverse lookup the brand. Hence the usefulness of the machiningdoctor web site. Inserts I buy from those are noticeably better and included the cutting info on the box.

@Susquatch
You can of course distrust everything and pay 10x the price, and get the same info on the box :)

Over Christmas one of customers dropped off 60-70 carbide endmills (slightly used), a few need a touch up sharpen, the rest I can not see any wear. As he explained it they do not meet their spec anymore and they are recycled (ie into the bin and scrapped), great gift.

What I meant is that some of the cutting info I've seen on the box is obviously bogus because it can't possibly be right. Most of it looks good though.

In fact, a box of inserts for steel with large radius noses just came in the mail today that have data that looks reasonable.

They are WNMG 433 with recommended usage of:

VC 370 mm/min (210 - 470)
Fn 0.25mm/r (0.12 - 0.46)
Ap 3.0mm (0.5 - 6)

I am a big fan of WNMG Inserts and especially the double sided ones. These were very inexpensive ($30 for 10) so I decided to give them a try. We will see.
 
For those of you interested, instead of throwing away a bunch of inserts no longer used at school, I picked them up looking for a better home other then the scrap bin. Here's a listing of what I've got and have no need for:

Pay for shipping and I'll get them out to you! Merry Christmas!

The calculators arrived, awesome implementation and quality.
Order the 0965-EN, the -DE has same info except in German. metric only.

Works for mill (cutters) and lathe (workpiece). shows metal removal rate as a bonus

See post #1 in this thread for contact info.

Front and back plus Niagara Cutter one for size comparison. The Garant implementation is plastic with no windows to trap dirt. Vs NC one that you have to pull out of a sleeve and won't fit in your pocket. Guess which one I will be using :-)

Very nice! That's the way I envisage stuff like that being handy and useful.

It's not really clear to me if it has both metric and imperial units Gerrit. Can you clarify?
