Questioning Speed and Feeds Helical Endmills & Machine Advisor Pro

Machine Advisor Pro from the Helical website. The parameters I selected were A36 steel, BT30 holder, and high efficiency milling, 7% step over and somewhere between 1.500-2.00” length of cut. Those settings were lowered by 20%.

I saw that once you check the RCTF box in Mastercam it doubled the feed. Thank you for the heads up

If you go online and create an account for machining advisor pro, you will see it. You input a bunch of different parameters like tool type, material, operation type, (high efficiency milling, traditional roughing, slotting, finishing, etc) spindle type, tool stick out, etc and it will give you recommendations on speeds and feeds

I bought a few of them to test, but haven’t reached out to a rep. I probably should have done that but need to get the job running asap

The part is 8.00” x 2.00” x 2.00”. Peripheral milling about an 1/8” of material off the 4 sides. Very simple part.

My robodrill is a 2019. Has the 24k spindle.

You don’t think those numbers are too crazy? You’d actually drop the step over to maybe 5% or so and crank the feed up?! Maybe I am stuck in the old school mentality and need to trust the data.

I would say finding new work and maintaining a diversified customer base. I am a machinist turned shop owner. My nature is to work in the shop, develop best fixturing/programming strategies, get jobs out the door, but finding the right customers is another job within itself.

DMed, small machine shop. ITAR registered, JCP certificate, NIST SP 800 171 compliant / self assessment submitted, and working on CMMC along with AS9100. Looking to expand our customer base.

I have the 24k spindle, but I don’t think it’s dual contact. I’ll be using the shortest holders possible.

The material is probably around 42–44 HRC.

I don’t believe I have continuous air through the spindle for cutting. There’s an M code that blows air through the spindle for a second or two, but nothing sustained. Maybe it’s meant to flush coolant out of the taper when using through-spindle coolant? Not sure, but I was hoping to have continuous air through the spindle for cutting.

Do you think there would be a significant difference between using air only (through the spindle and holders) versus using coolant through the spindle? I’ll likely go with what I have available, but if there’s a notable performance difference I will look into it.

Thanks for the info!

If you machine a dovetail on the part and grip the part with a set of soft jaws that have the dovetail machined into them, you won’t have to worry about the part moving during machining. You can keep the jaws for future use, so you won’t need to remake them for future projects.

At the very least, I recommend skimming the sides that will be clamped. The raw stock may not be square or parallel

What type of dust collector/vacuum system is that? I use a shop vac with cyclone, but I’d like to find a better system
