OI mb control V's 18 IMb control

[DiamondD]

Which controller do you prefer and why.

 

Reason for asking: I work for Vanguard Machine and we are trying to determine if the cost difference is worth going ahead and ordering the machines with the 18 controller.

We have Oi controls and I feel the 15 is really better than either control. The 31 is top notch but most machines do not come with them. I like the 18 control on machines I have used and think it offers a good screen graphic. The Oi's we have are with small screen and that sucks!!

I like the 18's we have better than the Oi's because they have the PCMCIA slot that we can run off a CF card for extra memory. The Oi's have very small memory, so we have to watch the size of our programs until later this year when we upgrade our DNC software.

I think the new 0i`s also have the card reader in them. I would also be interested to hear what is the main difference between these control other than how many axis they support and screen size.

The 18 can be upgraded in ways that the O cannot. HIgh speed machining options are limited on the O more so that the 18.

Does anybody have a side by side comparison of these 2 controllers?

[Newbeeee™]

The oi is only 4 axis. The 18 can handle more (6?). It is also a faster control at processing.

 

We have 3 chevalier vmc's (QP models) with oic.

The machines are setup very well. We're roughing at upto 275inch/min feed rates, and if you look at the control it is accelerating/decelerating very smoothly.

We are finishing accurately (std g2/3 ie no G08 or G05.1) at 160inch/min.

Whether that is chevalier setting up the parameters well, or whether that is fanuc 'standard' settings I don't know.

 

However, we had 3 x hitachi vmc's with 16 controls and 4 hori's with 15mb controls at a previous company. The best they could accurately contour at was 70inch/min!!!! We roughed much quicker, but the controls weren't configured for accurate cutting. The machines were junk, they just cut corners.

 

Back to the oi, CNC Apps Guy is correct about the limitations of high speed (G08/G05.1).

We're currently experimenting, and as configured, both options give the same ploughed field finish on the bottom of a pocket, where the tool profiles (ie g2/3 moves). Straight line it's ok. It looks like the head bounces 1/2 a thou when interpolating, it is that bad.

But we're working on it....

 

We've never used the graphics (been told they're very basic).

Thank you for your input. I will print this out and read all of them in are meeting. Please keep adding to this form. I will use all your information to come up with the right controller for are machines.

Simultaneous. X, Y, Z AND the Spindle. YES the spindle is considered an axis to the control.

I think it will do 5 Simultaneous - X, Y, Z, a Rotary Axis, and the spindle. I'll have to double check.

Some times the builder will tune the servos before leaving the factory. Seems as though they did that for yours.
