Let me state the obvious: the paper touch off and the automatic tool setter mentioned below are the only cases I know where the touch off is performed while the cutter is moving.

Cnc touch plate software for mac how to#
You want to use the same kind of paper every time so you can determine its thickness by experiment and thereby know how to correct the touch off for paper thickness. You’ll be 0.002 – 0.005″ or so above the touch off point, depending on your paper thickness. Lower the cutter until it makes the paper move. You want to stick the paper down between the touch off point and the whirling cutter using a little bit of oil. I find it is convenient to use post-its, because they’re in a pad that’s about the right size. Originally this was done with cigarette rolling papers, because they’re very thin. You would then use this information to determine your tool length relative to some standard, and you’d enter that into the tool table on your controller.Īnother method of measuring tools for length is the paper touch off. With this method of measuring tools for length you can determine exactly how far the tip of the tool is from whatever your gage block is resting on–vise jaw, machine table, or top of the part. Instead pull the gage block out of the way each time, lower the tool, and then attempt to slide it back under. Note that you don’t want to just lower the tool onto the gage block–bad for tool and gage block alike! The simplest way to measuring tools for length is to take a gage block of known dimensions, put the tool in the spindle, and start to lower the tool until you can no longer slide your gage block under the tool. How do we go about getting the length offset? Touch Off Let’s focus on tool length data, and moreover, let’s start out on the dead simple end of the spectrum. Otherwise, one machinist will do things one way, and the next machinist to try to run the job on the machine will do things another, and we may once again have a CRASH!!!! Measuring Tools for Length In shops with more than one machinist, it’s also vitally important that the whole shop be on the same page with respect to measuring tools for length. Just imagine what happens if the tool is actually an inch longer than what the controller thinks it is–CRASH!!!! If you’re running a shop, you’d obviously like to minimize the cost of managing the tool data as well as minimizing the chances the wrong data is in use when a part program is run. There are lots of ways to measuring tools for length ranging from ad hoc just-in-time methods to more elaborate systems that involve tool presetters, tool setters on the machine, and potentially even tool management software. We will describe measuring tools for length via touch off and tool setter in this article. The controller needs to know how long your tool is relative to some standard such as the “gage line”, and it is often nice to know exactly what the tool’s diameter is as well, since tool diameters fall within a certain tolerance that may affect the accuracy of your parts. CNC machines require tool data, by which I mean length and diameter information, so they understand exactly where the cutting is happening. Tool Setter: Measuring Tools for Length ĬNC depends a lot on accurately measuring tools for length.
