issue with lock dados

[Thomas strembitsky]

hi I just noticed this on our last few cuts and also when going to assemble the cutting for the outline pass seems to be cutting deeper on top of the tongue. im running control nesting 5.84 and ecabinets build 17
ive attached a few photos too[

If you are doing flip ops on these parts, it looks like the sheet or parts are slightly miss aligned when flipped.

If they're not flip-ops, look to see that the bit diameter in your tool table hasn't gotten changed.

If you look closely at both photos the tool cuts deep on 1 of the tenons and shallow on the other by what looks to be the same amount. That tells me the part shifted when flipped. Happens to us every once in a while if the operator gets sloppy when flipping a sheets. If you are doing flip ops first take a look at your pins to see if one is damaged.

This has always been a flip op problem with us.

Thomas,

This certainly appears to be a fence/pop-up pin location issue. If the values to the pins are incorrect, you will see twice the error when flipping sheets. If a pin or the machine has become out of alignment, this can cause what you are seeing. You may want to verify your fixture offset value (or fence macro value if doing it the older way). You may want to also ensure that the machine and pins are square to each other. I have always found that the best way to get/confirm the pin locations is to put a sheet of material into the pins that has been trimmed on 2 edges by the machine. Place this sheet into the pins, turn on vacuum, then lower the pins as you would do in normal production. Next, touch off the edges with a known diameter tool or solid pin and subtract the radius of the tool/pin. This can also be done using a dial indicator etc, but this method works very well and does not require special tools. If this is not your issue or you need more help with this, please feel free to contact us or CNC Automation for help.
