Feedrate by Infrared temperature control?

[ibewgypsie]

I got a good one for you.. I am playing with the ideal of a camera mounted on my mill. A infrared-ccd type camera, I am working on a scanner using a mirror-laser led. By triangulation to figure contours. (I bought a laser barcode scanner to take apart)

The gist:
I heard someone say onetime if it is throwing blue chips slow down (meaning they are hot). A infrared camera can see heat. Intensity of pixels on screen can be read by simple vb commands. If it gets hot, coolmist it, if it gets hot, slow it down. Would not take long to get a schedule of temperatures that mills can exist at for optimum use.
ie: feedrates per rpm per mill sharpness at the moment. Kinda like a exhaust sensor recalculates the mixture. If ya really want to get fancy, they got these handhelds temp sensors with 232 ports and a laser led.

HUH? any comments on the logic? Looks like it'd work to me. Probably make the camera work full time instead of just a scanner.

Anybody need a new project? Here ya go.. get to work.. send me a check if it takes you bigtime.. HA.. Like anybody I know that is rich remembers me.. HA..

Didnt you just post that you needed a clone to cut up 55 gallon plastic drums? And now you want to make a cool project like this! Dont tempt us.... clone your self twice. The two can run the shop and you can sit, email us cool projects that you (or them others) finished and your wife will be so happy to have you around more!

Also - Intresting idea, if I make millions on it I'll buy you beer for life. Grins and a beer. JG

Problem I see with it is getting a camera that will read something as small as the tip of the tool, without reading the chips or the rest of the tool. If it reads anything else, it may be too late to save the tool by the time it reacts to the temperature.
We used an infrared camera to do something like this but it was using a much larger area. Even that had it's drawbacks.
You would also have to know the emusivity (sp?) of the item your trying to read, although if your just looking for a temp change, you could do without it.

The temp is not necessarily an indication of cutting too fast. I can see being able to pick out the "hottest" pixels on the screen no problem. But, how do you decide that you're cutting too fast or the bit is dull? If you slow down in SS it will get hotter. Also, how do avoid the pixels going into saturation? Visible light will affect the image. The light sources in the shop emit some infrared. Specular reflections from the work, the tool and the machine may overwhelm the sensor. Those reflections are not predictable.

If you want to experiment use an infrared filter on the camera. It so happens that fully exposed and developed color film (the black looking part on the leader of 35mm film) is an outstanding IR filter. It passes only 2% visible but 97% infrared.
