RhinoCam Ramping moves.

[kamcad]

Hi
I am currently using Artcam as CAM software, but since I also use Rhino, I am considering switching to RhinoCam. What I fail to achieve with it is adding ramping movements to each step down layer. So far, I only manage to get lead in movements on the first step down layer.
My question is whether I can get a similar movement with each step down layer in a pocketing or roughing operations ?

Thanks in advanse

Its a few years since I used RhinoCam and ramping was my preferred entry strategy.I can't remember any issues with ramping on anything but to be certain,you might fire off an enquiry to Mecsoft.If they can see a potential sale resulting,I don't doubt they will soon provide an answer.

The answer is yes. There is a check box in the entry/exit dialog tab that asks whether the entry/exit criteria should repeat for each pass.

It’s an old post, but wanted to say, that option you have advised is not ramping, it just repeats entry / exit at each level by raising a tool and entering a path again, waisting enormous amount of time.

Rhinocam lacks a ramping option, while it’s a quite crucial option for a smooth machining of wood ..

RhinoCAM has ramping, they just don't call it that. You can do a helical entry or a straight ramp in by unchecking the helical box. You don't have to do at each level if you don't want it to. There's some explanation here: https://mecsoft.com/OnLineHelp/Rhino...hing3axis.html

When I checked that link it led to the entry that relates to adaptive cutting operations.This one may be more use for cutting profiles: https://mecsoft.com/OnLineHelp/Rhino...entryexit.html .The index for the help section isn't the greatest but the software does a good job.

As I have mentioned earlier, entry / exit ramping is not the same as plunge ramps. Yes, you can repeat that on each level, and you might get away with that that, but it’s completely different than having dedicated options for the plunge ramping on each pass. For example: you need a certain entry / exit, and different kind of plunge ramping on each pass, you are forced to use multiple tool paths, or you have to manually correct G-code. Most of the time when I need a custom ramping, I end up editing g-code or even using a different software.

I wish I could do everything in RhinoCAM, in one path but especially ramping is far behind compared to the competitors software

Did you follow the link I posted and note the check box for ramping at each level?You can also choose a ramp exit,but I have never done that.Just as I have never selected different ramp geometry for each pass level.

With all respect, I think you didn't read my message carefully. I'm not here to seek for a help, I know very well how it works and I'm aware of the check box.

It's stated clearly in the user guide too: "Entry and Exit determines the way in which tool enters and leaves the part geometry." The check box only REPEATS entry / exit on each level. There are no ramping options for in between levels.

It's very simple: you have a sandwich panel that has a top / bottom layer of different material than a core. You need to enter material using very shallow angle and speed to avoid chipping. Between levels you have to ramp into the new level without ever raising a tool + higher speeds. On exit you have to go out in a shallow angle too. Have fun achieving this in RhinoCam while other software has no problems, because they have dedicated options for ramping in the between levels..

I have to admit to only machining a few dozen sheets of composite panels with a honeycomb core and the daily output wasn't such that a few minutes difference in cutting mattered more than the time spent programming the ramp moves.For the thousands of sheets of melamine faced chipboard I have worked with,I just use the simple ramp entry.I don't doubt that for the same components repeated a huge number of times that there is a gain to be made.

Have you communicated your concerns to MecSoft? They're pretty easy to work with, and seem very open to enhancement suggestions. I've probably had somewhere around 20 suggestions over the last 8 or 9 years implemented in the product.

That's where I really drifted away from the RhinoCam - we had to create the toolpaths for the mass production. I agree that machining one-offs you can get away with any tool path. But if we are talking about 10 000 / 100 000 items - every second is saving money and time. I remember the first massive job we did by the other software it was ~60h saved in total machining, after that we decided that RhinoCam is not for us.
I know there are thousands of folks using and loving it. I would never look back to this software again, but one client insist us to use it, because someone told him 10 years ago that this is the best software in the world, even he knows ain't s**t about CNC. So from time to time I'm still googling and hoping that they have implemented some advanced futures for the 2D milling.

I would definitely do, if I was still on the board.. To be honest, if I would list my concerns now - they would have to build a new software from the scratch.. Right now, coming back to the RhinoCam again, I see flaws almost everywhere - just because I used to the other software workflow. It might not be flaws at all - just personal preference.
