GCodes, Offset Tolerances and Easy Repeatable Toolpaths

I laughed the other day reading
a Fanuc CNC programming guide when
it did not accurately capture the
need for the following when tracing
cabinet parts outlines:

Offset tolerances need to be at minimum
in the 3/32" range when working with case
sheetgoods, due to shear tear-out and finish
sanding needed post-cut. Anyone programming to the .000 thousandth needs to account for this
variance. Again, you are making parts that need to be hand assembled, prepped, and spray finished. Keep this in mind, maybe two end panels would have been done better by just cutting on a sliding table saw. Think about your workflow before working...it really does pay off !

Toolpaths needed to be thought out in
advance, ie the Atc tooling head needs to
Be told to drill shelf peg holes BEFORE
cutting to dimension the actual part.
Vac tables being what they are, they cannot always hold perfectly and the machining force
of 37mm setback hinge holes is enough to twist and damage the part being skin-cut. I saw this at another cabinetmakers shop and immediately pointed it out. Problem?...solved.

Slow the ipm travel paths to an optimum cut speed, trying to show off your latest Thermwood Cs43 by running it to the envelope just leads to broken pcd bits that cost 565.00 each from Royce. DONT DO IT, it also leads to gantry misalignment over the long term. Stick to speeds below 700 ipm or even less. No one drives their car with the needle buried, why do this to your CNC ? A second toolpath pass to drill or shape in two runs may result in a better finish than causing "chatter" on a cabinet door edge. The old adage, sometimes two small steps together leads to a big step of accomplishment over time.
This can be applied to any wood shaping approach.

This is the best Cnc guide I've learned....
Blows away the shitty Thermwood Manual...
Just sayin'...!

Always test cut your custom g code program on a spoilboard.!!! No one bats .1000 !

Any island or casework wider than 4 feet should be assembled on site, don't trust our shitty Halton roads, the vibration is just unreal at causing shifting and racking misalignment.

Less glue is better, Titebond has a hold force of at least 2000 psi, sanding off sloppy glue from an end panel or frame join may take longer than you think, you can always add more.
