Hi I just got my Pro8+ setup and am using Vetric software . I am having trouble setting up my tool database for the Amana 46282. Could someone offer the correct database info for this tool . I have listed it as a tapered ballnose but don't know the data I should input . What speeds and feeds should I use for soft and hard woods Thanks in advance for any input

I can't believe that the Tool Database/Import does not work. I have never heard of that ever being an issue. If that is really true, then it is an issue for Vectric support. Are you using a registered copy of Vcarve or Aspire?

Barry: If you're wearing that hat when tying to work with your computer or cnc machine, that is probably why you're having a problem adding tools to the tool data base. LOL

In all seriousness I am looking for some actual speed and feed numbers. Particularly because some of the tooling I have is not Amana . I have some Yonico and Freud that i also need to enter and they don't have a data base download . I used the Amana 46282 for my question since it is quite unique because I want to know about the bit . Loading a database doesn't help really . If you cannot answer the question I understand. .but to suggest use a database which takes no account of my actual machine is not what I am asking
To cover the remark regarding my hat I only wear when crossing the border LOL

You can use the feed and speeds from Amana for other bits if they have the same geometry. That what I do and probably most others on this site and many others. Much of it is really an estimate anyway. The type of wood your cutting changes the speed anyway so it's a lot of trial and error. There are lots of feed and speed charts on line, but when you start cutting, your ear will tell you weather your cutting correctly. With using a spindle, because it's so quiet you will be able to tell when your cutting correctly. Even with a speed and feed chart, you're going to break and burn out some bits. It's really all part of the learning experience.
I do really like the hat!

Once you create the tool or import the tool from my exported list linked above you'll have the tool type and default parameters that you can change if you want. You may want to get the free 30 day trial of G-Wizard: www.cnccookbook.com/cnc-router-feeds-speeds-calculator/Or even buy the tool as any default values are seldom used. The tool list will work for any machine as it's about geometry and not unique to any machine. Actual tool parameters (ADOC, RDOC, speed, feed, chip load) will vary with every cut but there is a wide range of what will work. Material removal rate, tool deflection, tool stick out, TIR are important control parameters as the material you're cutting. The desired finish roughness is a function of step over. Everything gerry and steve said above applies to you and your machine but what you asked for is only a starting point. Your tapered ball nose cutter is pretty normal as well as your machine and not unique. Toolpaths are a very deep and complex subject with many exceptions but also fairly flexible. The reason every toolpath starts with a default value for a particular tool and has an edit option right next to it is that you will use it almost every time.

Hi I just got my Pro8+ setup and am using Vetric software . I am having trouble setting up my tool database for the Amana 46282. Could someone offer the correct database info for this tool . I have listed it as a tapered ballnose but don't know the data I should input . What speeds and feeds should I use for soft and hard woods Thanks in advance for any input Here is mine.....I by no means an expert on this but its a starting point.... From my experience (AR4+Pro) and doing mostly 3D carvings in hardwood (maple, walnut, cherry, purpleheart, etc), this bit (the 46282) is my "go to" bit for finishing paths (I use a 1/4" ball nose for roughing). For anything between about 6"-15" tall, I use this bit exclusively. For smaller, I use the 42280 (1/64"r) and for larger, I use the next size up (1/16"r, depending on the side angle required). I bought the Amana set that (AMS-136) has a good variety of bits included, so it's a good starter set to see what works for you. I think that RetiredAFChief's settings are on the (very) conservative side, both for feed rate and for stepover. I use 100-125IPM and a 7% stepover rate. I usually start with 18,000RPM (300 on VFD) and then adjust by sound/chips. I am pretty certain I could go faster (on feed rate), but I don't want to mess with success, and I find the smaller step-over pretty much eliminates sanding (I usually use a brass brush and go with the grain to get rid of fuzzies and to open up the grain a little bit, and then some sanding in the 120-150g range to remove tool marks, and then use steel wool (#2, 0, 000) usually. I have used every variation of the 3M scouring pads, and I wish they worked as well as steel wool, but they don't.
