speed/feed

[gc3]

Since a lot and I mean a lot of guys ask about that I thought...well why not, just for fun to see response from...

Always amazed on many forums questions asked without OP making any effort to learn...

Gene you do some really nice work. Looks complicated, but beautiful.

Like the "Layered" one a LOT:)

A lot of people who join the forum ask a lot of questions.. yes. But, is that not the whole premise behind having a forum? Or are we all supposed to figure everything out in private?

Coming from a woodworking background, I had a pretty good idea what feeds, rpm etc I should try and cut wood and plywoods at. However, cutting on a CNC router IS differetn than that of a saw, shaper, etc. And, I have to say that the members here who helped me are more than generous with their combined knowledge and eagerness to assist people who need some guidance. I certainly asked many questions and received some valuable help that saved me many hours of time to get to where I needed to be. I'd like to think I have also helped some others as well.

If it bothers/annoys you to see people ask for help, or for a starting point due to their inexperience or possibly since they are trying to cut a material that is new to them - ust pass those threads by. But, I beleive that the forum is primarily a place to help one another with technical problems and solutions. Otherwise what is the point?

Asking questions IS making an effort to learn.
If every person had to learn everything on their own with no outside help it would take a life time to get good at anything.

Gc3, I'm sure when you started you ask what many would see as dumb, lazy questions to get headed down the correct path. You maybe the Edison of speeds/feeds by making your own bits, chip load charts, steppers, spindles, Cadd/cam and control software but others are not and do not feel as brave cutting new things.

As some else on this forum pointed out to me: just give people a good starting point so they have success will make them happy, and give the confidence to start tring things on their own.

Some people, like myself, are so new to the whole scheme of things that they (I) don't even know how to ask a question. We read the books and manuals, but they may as well have been written in a foreign language. Like Kyle said, a good starting point may be a little elusive sometimes. But, the good news is that if you truly are interested in the subject, the doors will start to open and the fog will lift and you will start to make some really amazing things....joe

Perhaps it's not that fact that people ask about speed/feeds etc it's that they ask when the information is easily available with a quick search. How many time recently has someone asked for feed/speeds on aluminium for instance?

I can appreciate both sides of the discussion.Feeds and speeds is a good example of there being lots of previous posts but yet I'm still perplexed after reading them as well as going to the Onsrud, Centurion and PreciseBits sites using Google and trying some calculators. In my case, I can go through their processes and end up with a number such as .02 or .008 but then what do I do with that???

Virtually all of the manufactures charts and such assume that the person already knows some basic info but, if not, then it's no good. It's unfortunate that at least one of them doesn't put together a starting from scratch video tutorial. They'd grab a lot of the newbies that way - some who evolve into large users.

Example: I just bought about $600 worth of Centurion bits because that was what was recommended to me. I'd never have bought from them otherwise because their website is so poor. The down shear ones come as plunge and FEM. Nowhere do they tell me what FEM means. They don't offer any support info to speak of really so I suspect they loose a lot of would be customers who are just starting out. My order arrived a couple of days ago and guess what; not a label or part number in sight either on the tools or the containers. I've no idea which are plunge and which are FEM and I'm certainly much more likely to use the wrong one sometimes. Grrr.

Onsrud provides both markings and feed & speed charts so good for them. Now if they would provide explanations of what each column and abbreviation represents and how you apply those numbers it would help this geezer to grasp how I can use the info to actually calculate my feeds and speeds.

Grumbling aside, it takes a lot of thought and care to not assume even the simplest little thing that can block the newbies ability to understand. Most companies just don't invest in training and well written documentation any more, which is unfortunate because that was often their best weapon against the offshore suppliers.

But why is it such a problem? After all, people are also a social bunch. I don't mind having people on an Internet forum ask the same questions. After all if it bothers anyone to answer, just don't read it or don't post.

It's not like they are ringing you up at work and you're taking your own time away from something. It's your choice to help another person out or just pass that one by.

I like asking questions. Been that way ever since I was in school. Some people just do better when dealing in a discussion vs reading something. It doesn't mean they are lazy or trying to take the easier way out.

After all - what is this place for?? Just showing off work we do, or sharing our knowledge and giving and taking from that collective knowledge base? I don't find it troublesome that similar questions are asked often. It just means more, eager Shopbot users are buying machines and trying to use them.

No ones forcing any member to read or respond to any post. If you don't like it is it that hard to skin to the next topic?

[Brian Harnett]

This happens on any forum a thread of the same question, each person asking has a genuine interest and if they did not do a search so what, answer if you want or don't.


The chainsaw sculpture forums has the same questions asked a million times over when someone is new to it, there are a few that will help and a few that will give condescending you should know that type comments comments also.

Not quite sure why this thread was even started.
