Forgot the trick

Post by M Farris »

Hi all,
It has been a long time since I have posted and I hated missing McGrew's camp this year. Since I left my job a little over a year ago and went full time with the CNC it has been a little busy, but great.

I have used this trick before and thought I had it wrote down, but who knows. I am cutting a shallow pocket in a panel to accept a carving. I will be using the carving boundary by offsetting outwards once, inwards twice, and outwards once by the diameter of the bit...... or 1/2 the diameter of the bit? That is what I have forgotten. This allows for the bit and creates a tight fit. A little help please.

Thanks,

Offset outward by the radius of the bit
Offset inward by the diameter of the bit

There's also a gadget that does it as well which can make things a bit easier if it's something you do a lot - http://forum.vectric.com/viewtopic.php?f=47&t=27848

Thank you, much appreciated. I have to learn to write this stuff down.

I am trying to get my head around this:
1 step to the left
2 steps to the right
1 step to the left.
Doesn't that get you right back where you started? :?:
Cheers

Yes but each time it's rounding the corners by the radius specified so you need to do it that way to get the inside and outside corners converted.

For a single rectangle the fillet tool can be just as quick without having to remember to alter the offset radii and direction of offet.

Can someone remind me why this is a better approach than using an inlay toolpath? This is a practical question, not snark, as I am about to do this exact thing in expensive signboard and I would prefer not to mess it up.

Because I remember and understand the offset method, and I've not tried the inlay toolpath to do the same thing.
