Adaptive Clearing Online

Monday, September 12th, 2005 at 10:31 pm Written by:

We had it working in the past, a version of Freesteel that can be run via cgi over the web. Well, it’s working again, follow this link. It is quite fun to write web applications like this, I have certainly learned a lot about scripting and dynamic web pages. There are a lot more things that could be done to make the online version more useable, but it will do for now.
The main purpose is to point interested people to the online version to test the algorithm for themselves. It is effortless to use, and if you are prepared to install a plug-in to visualise vrml worlds, it could almost pass as a graphic, interactive demonstration version. It might be easier to ask somebody interested in our work to use a web interface than to give them a CD or ask them to download a demo version that needs installing on a computer. More advantages are: no need to write installation procedures; being independent of any operating system (all you need is a web browser and access to the internet); usage is easily traceable (a demo CD might just end up in the bin).

    Would be useful if you could give some links to some STL files to play with…

    Gave a try at the online version, seems its only for ball nosed tool and not for toroidal /bull nosed tools (insert type). Also toolpath calculation calculates for the whole of the area and then validate removes the segments which cant be machine. It will be time saving for algorithm to do it in reverse way find regions which are accessible by tool and calculate offsets and Z slices for only that regions.
    How about using Java 3d for your site the interface can be more user friendly.
    I read your other strategy you opted to make it opensource. I have been looking for cam projects for quiet a time no and only found opencascade a tru opensource but its mostly for cad and havent been explored for cam

    What parameters did you give it? I’d like to know so I can go through it with you. We find most people don’t understand what is going on because we have explained it so ineffectively, so this would be a sure way to help us correct it.

    Your suggestion of the way to do the algorithm is the way it already works! I guess it’s not obvious.

    I’m quite acquanted with Java, even online. It’s too bloated. I am trying the server-side-images/svg/javascript route because it just might work.

    I’ll comment on open-source stuff in another blog entry.

    Julian , Nice to see a quick response. I am not sure how the alogorithm works for toroidal /bull nosed tools eg 52 R 6 . Here large step downs wont be permitted. The algo would be good for solid carbide tools where we get sufficient flute lengths.

    Regarding my earlier testing . I have uploaded a stl and caculated toolpath with 12ball and default settings the caculated toolpath segments were in the region where tool could not enter , only after validating toolpath the gouging segments were removed.

    Also would like to know how to calculate two way toolpaths ie both climb and conventional.

    Does the algo take care of cusp left by earlier passes (slices).

    I can volunteer to do testing debugging for you.Can I have your mail id. I can send you pic of test results

    The online version seems to be have taken off for maintenance. In the new version it would be nice if you can add some help regarding the parameters , and also provide a small example.

    Over the past few years, i haveseen a handful of companies that have very successful web experiences despite strongly decentralized organizations. We set out to discover what makes these companies’ sites more effective, and found some consistent characteristics.

    Hmm. What was Fred trying to say? Is this a spam attempt that was successfully foiled, or was this an in-depth analysis of ‘web experiments’ of the corparate world in comparison to individuals? Will we ever find out?

    I dont know but why i don find such informative and profitable blogs so often,I suspect blogging world is becoming so small that we cant find such lucrative blogs like this one.

  • 10. Alisya replies at 2nd March 2007, 7:06 am :

    I suspect that’s thereason general public want to read blog….Internet visitors generally create blogs to declare themselves or their secret views. Blog grant them same matter on the monitor screen what they specifically needed,so as the above stuffs declared it.

    My main concern is that you can’t guarantee every page of your website will be included in the SERPs. Considering I’m constantly adding new products to my company’s website, I need to be sure that customers can find them as soon as possible.http://www.seoptimizerz.com
