Hy Gregory.

To me Rhinocam 2012 is ok as CAM software since they have introduced 5 axis simultaneous module, it has a lot of post processors but mainly has APT output option which is not reacheable on higher level CAM software such Powermill or Mastercam, APT is not a standard option for output file. Rhinoceros is a perfect modeller and I found it most intuitive and well suited on my kind of logic in building surfaces starting from points and curves.Rhinocam being integrated with Rhino is perfect.I am interested only by milling materials, soft materials, composites, wood and maybe light metals as aluminium alloy.My first interest was for creating boat master models, therefore large parts but studing all ways of generating shapes, double curved surfaces I found that the best option is a robot milling cause is necessary to have 5 axis and robot offer 6 axis. Of course for large parts a linear track would make the job easier offering 7 th axis, translating the robot along your model as you can see in my video I posted here on rhinofablab. I am not an experienced user, only a well informed person and I studied many options from the market.

Hi Victor, this is true we don't have as many features as the established robotics softwares, but Grasshopper is so fast for building specific applications that it can become more versatile than these specific software products. Other than milling, what specific features do you need? - we are always interested in getting feedback from experienced users...

Hi Gregory,

you still need to work till to compare with Rhinocam 2012 and simulation software for robots, Eureka,Workspace 5, Irbcam, Robotworks,etc.

More about cnc, goto cnczone or Machsupport.

Hi Victor, Godzilla is a robotics simulation platform - designed for people to build their own applications.  As we have only just released the software, there is no specific milling applications available yet - but we will post a simple example to get you started with developing a GH definition...

Hi Gregory,

I checked again and I saw that Kuka/prc is a beta software, experimental yet but is an appreciative thing your trial, it seems to be a solution dedicated on arhitecture work not for a large use in milling.

Hi Nichloas, sounds like a labour of love!!! Bear in mind that the controller is there to smooth the current using inverters, and controls the motor speed through managing the (high) current, plus a computer to manage the kinematics - so it might be worth searching ebay for some spares...

Hi,

In my opinion the information is very poor and unclear for me on the website you indicated, where you establish cut levels, tolerances, tool angles in a roughing milling operations, where are operations you could choose 3 axis or 5 axis, on the Grasshoper site there is no information about these aspects. Who sell KUKA/prc , there is too less information on robotsinarhitecture.

Hi Victor, good questions! We have made Godzilla as simple as possible, but if you look closely you will find that all the features needed to build robotics tools and applications. The timeline is the most powerful feature, as you can set the "actions" to write spindle speed or feed commands to the code a certain points along the path. We haven't built a specific CAM application yet, but if you can define a toolpath with curves, and divide this into planes (e.g. Perpendicular Frames component) the robot will follow it. Double click on the Tool component to select the milling tool, or build your own. We will post some videos soon...
