    How to use Robot Service Requests on a fanuc robot

    Thanks, i'll try there too. Excessive accuaracy is a sign of poor breeding. -Socrates.

    How to use Robot Service Requests on a fanuc robot

    Hi all, I've aquired an old Fanuc robot, an LRMATE200i. I have all the manuals, and i've worked out how to write a program that works well. What I'd like to do is have that program activate automatically when a component arrives in a hopper. I know this can be done using Robot Service...

    auto-scale a drawing

    That's what we do at the moment, but then there is no point in having a factory of parts. Or even a CAD model come to that! Also a huge table of dimensions (it's over two pages) is unweildy, and leads to interpretation error. Excessive accuaracy is a sign of poor breeding. -Socrates.

    auto-scale a drawing

    Hi, I've built a family of parts model, and I'm referencing the model parameters in a drawing so that as the model changes the drawing automatically updates all sizes. In this way I can use one model to create different drawings 'on the fly'. It's a massive time saving. But: Sometimes the...

    Question About CNC Software/Hardware

    My questions are: 1. Is that a fair or accurate price? Get quotes from competitors. Ask around. Ask if you can visit some other companies who are already running the machines (which is always a good idea anyway) - when you get there ask them how much they paid. 2. Is a specific companies...

    DNC stips out first line of program

    ah ha, fixed it.. there was no <CR> (carriage return) marker for the program to look for when it sent it to the machine, so it was just stripped out - removing the first line. Excessive accuaracy is a sign of poor breeding. -Socrates.

    DNC stips out first line of program

    That's a useful hint, (sending back an empty file) but no. Say for example I have this program: %1000 (EXAMPLE PART) (PROGRAMMED BY KNOBHEAD) G10 etc etc When I send it to the machine it will look like this: %1000 (PROGRAMMED BY KNOBHEAD) G10 etc If I then send it back to the PC %1000 G10...

    dimensioning to mid limit

    I'm sure there is a way of doing this, but I can't work it out. Our manufacturing guys want all our models done to mid-limit sizes, so that they can drop the models directly into their CAM software without any edits. Historically, we've always dimensioned tolerances in our parts in a +0.2/-0.0...

    DNC stips out first line of program

    Hi all, we're using Edgecam's DNC system to send and recieve programs to our CNC machines. My problem is it seem to always delete the very first line of any program each time it is used. Normally not a problem so much, but if a program is sent back and forth a few times (edits, backups, etc)...

    fanuc tool length management 11m to 16m offset to 999,000

    There's a million ways to crash a machine - get round this one and they'll find another! Seems to me either your operator was having an off-day, (even the best guys have a hangover occasionally) or you need to look at your operator training. He's just had the best training already though -...

    Anything new to talk about re: machine controls?

    Mazak do have their own cam system, called Camware, which I do use. But the interface is different to the machine, and the backplot isn't as useful as the backplot on the machine itself. Camware isn't the most user friendly program in the world, but your stuck with it on mazaks if you want to...

    Best way to machine features facing opposite directions on 5 axis

    Hmm, you could use a spindle probe to check your position before machining the second side. If you're feeling ambitious, you could even create a feedback loop from the probe to automatically correct itself. A decent 5 axis machine shouldn't really struggle to do this, it is what they're for...

    Anything new to talk about re: machine controls?

    'easier and faster' always seems to be at the expense of 'flexible and powerful' - I use both Gcode and Mazatrol. If I'm doing something straightforward, mazatrol is great. Quick easy, accurate. If I want to do something a bit weird, bend the rules, then mazatrol is fairly useless and I...

    Drawing gears

    If you want to draw an involute, you have to go back to the old manual drawing board techniques and develop it 'long hand' so to speak - there isn't a quick way (that I know of). You might find someone somewhere has done a LISP routine to generate them quickly though.. I'm sure you know how to...

    Sore arm and Shoulder

    The other thing with a trackball of course, is that you don't need a surface to use it on. You can put it on your knee and sit right back in your chair - maybe put your feet up.. Excessive accuaracy is a sign of poor breeding. -Socrates.
