WinCNC , Tracking sheet count per bit, possible?

4/29/16       
Matt

I will contact WinCNC directly about this but also wanted to graze on the thoughts of the folks here.

We are trying to find a way of tracking the sheet count of our individual bits between bit swaps.

Router is a 4x8 CNT Motion, using WinCNC on a desktop pc.

The only tool we routinely change during the day is the main cutter tool 1 (going from ply to melamine, to occasional hardwood).

Other than that, they all stay in use until worn out.

It's tricky to keep up with a sheet count on them all, but we have been having issues with premature bit failure (particularly 8mm back Dado and 5mm line bore).

We are in the process of solving that issue, so I'm not directly addressing it here. Just looking for ways of tracking sheet count on each tool in WinCNC.

Open to other methods of bit tracking that don't involve a paper and clipboard apocalypse.

Thanks all!

I have used Wincnc on multiple machines since 08, pretty sure it will not do a sheet or file count. my operator has a sheet list and ticks off completed sheets because we are loading a run file for each one. I am pretty sure you are doing the same.

Thanks James, and yes, we are. We don't currently track all the tools because there are 8 of them, and they all get replaced on very different intervals based on cut quality. Having my guys track all 8 of them manually (esp. with some just being a couple dollars) isn't a good return on investment..... but if WinCNC had a way of doing it, it could prove to be very helpful.

Thanks!
Matt

I think this would have to be done via manual spreadsheet. But you should be able to track the sheet count based on the cam program you're using to generate your g-code.

The word from WinCNC is that there is no plugin for it available, at least not one generated by them. I'm not sure if WinCNC is open source or not, someone may have produced such a thing.

Basically I think the ideal plugin would be something that tracks the sheet counts starting a 0 every time you calibrate the tool. Generally speaking, we only calibrate the tool once, use it until it's spent, and change it. So that sort would work great for us.

We are currently just using a sharpie to write the date on the bit, and that's so-so, I'll keep looking.

The spreadsheet idea sounds interesting but I'm trying to avoid having the CNC guy have yet one more step to worry about.

Thanks,
Matt

It's possible to do this, even without a plugin/etc. It is more complicated than you might like though.
Wincnc allows you to output D/A signals to auxillary outputs. You can pretty easily hook up a counter and output the signals to count at various points, and restore the count to the right number each on tool change. You can use the local position storage to store/restore the values for each tool .

So, yeah, if you really want to do this, and there is no other mechanism, ...

I am not familiar with the control, but based on the link above the control has parametric capabilities? Does it have a variable register? It would be a screen with variables (usually numbers such as 100~199, etc. They are called within most Gcode programs with the # symbol)
If it does, this could easily be done with a sub-program call and set a counter up for each discreet tool, then you would simply refer to variable register to look at the count for each tool. Hope this helps

Matt...
There may be a couple ways to do this.

1) See if you can glean the required info from the WinCNC log file. Run time, tool run time and I/O info is in there. You will have to open this into Excel or another spreadsheet app and manipulate the data, and it may not be as accumulative as you need. And, unless you put a discreet signal at the beginning of a sheet, you will most likely not get that info. Maybe an operator button?

2) Use a bank of digital counters and/or hourmeters hooked to discreet outputs and clock each action. Could be a simple version or have a PLC added to give specific information.

FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
