Re: Cut Outs for Electrical Boxes in Plywood

1. What is the best way to get to specific measurement on my plywood to make my cutout for an electrical outlet?
2. What is the best way to set up the cut to get the exact size of an electrical outlet?
3. What size and type of bit should I use to get the best accuracy and cleanest cut? Currently I am using a 1/4 up cut bit.
I am currently using VCarve Pro
Any other suggestions would be appreciated. Thanks!
1) You would measure the location just like you would measure it if you were going to use a saw for the cutout. You would measure from 2 edges of the plywood to locate the cutout, which means that the X0,Y0 would be at one corner of the plywood.
2) Normally when you are setting up the job in CAM, you tell the program the diameter of the tool bit and the program subtracts (or adds) the radius of the bit to cut the correct tool path. So for a cutout, you would subtract the radius of the tool because you want the tool to cut inside the outline. So using a 1/4'' bit, the tool path is 1/8'' smaller, per side, than the desired cut.
3) You might try a down cut or compression bit, but you can not plunge in with these bits, you have to ramp in. Alternatively, you could just cut from the back side where a little fuzz/splintering on the cut edge would not make any difference. Should be cleaner than a saw cut.
