AC servo and DC brushless motors are I believe one and the same for all intents and purposes. An induction motor cannot be described as a servo motor as its low speed performance is generally a bit

Did somebody try to get rid of the feed screw all together and replace it with a hydraulic cylinder? At the first glance it may present several advantages: no backlash, big force at low

synchronous I've been confused between DC Brushless and AC synchronous Servo motors and thought I'd sorted this out, but now I'm confused again. The MAC AC Servo motors by Indramat (now Bosch

Hi, I need all the help I can get as I'm trying to build my first cnc router. I have basic cnc knowledge, and I have a complete workshope. I need information on how to start, what do I need to know,

I seem to remember some one was asking about an inexpensive PCB machined. This may work, i have heard of them being used before.

As long as shameless plugs are in order, have a look at Axis Wizard, under Belfab URL, in the tagline. Probably doesn't do quite as much in threading mode as Wayne's, but it does do threads as

Yes but moving from x(0)y(0) to x(1)y(1) requires the same sort of calc. However you cut it though, the inherent differences in accuracy at differing radii in polar machine, is the death knell for

Bill, Haas resently paid Hurco some big bucks in a patent law settlement to use conversational programming on their controls :~) Seems Hurco has some patents on the machine side of conversational

Wayne, Please do give us the shameless plug. It is considered acceptable for your to explain what you have, give a price, and answer questions about it. You just have to conduct actual transactions

My friend uses them and swears by them and not at them. http://www2.automationdirect.com/store/Home/Home

Conversational why conversions where I worked. They are conversational and for short run or prototype they could not be beat. All you need to do is follow the menu and answer the questions! After

Bill - I ran across this site recently: http://www.programmable-controller.com/ Looks like an interesting approach... Regards, Carlos Guillermo VERVE Engineering & Design

Okay. I'll pose the design to a few folk that I know and see what they say about the EMC running it. It will not be programmed with polar coordinates at this point. Ray <s>

Fred, I have to agree with the other Ray H. A Polar machine/software making a move from X(1) to X(2) must calculate every position along the path, whereas a Recti-linear machine merely has to say' "Am
