Will more than two decimal places cause trouble for milling and engraving?

Hi,

I am working on a design that also gives the possibility of small letters being engraved instead

of being silk printed, using milling cutters with a diameter below 0.2mm.

 

Even though any dimensionn of the parts is "spot on" (i.e a knob hast a diameter of 18.0 mm

or a cutout has 120.4x30.4mm) the line withs of the engravings are not.

I designed and measured the typos using two decimal places.

So the desired line width was beteen 0.58 and 0.38mm.

But switching to three or four decimal places

while using the measure tool revealed that the line width is not spot on.

Could be 0.3812mm or 0.3805mm.

Now, the letters are just decorative. Nothing has to fit or pair mechanically

But I am worried how a CNC machine will deal with data that has four decimal places

instead of two or only one. (It will be probably a Datron Neo)

Should I rework the line width? Is there a possibility to "throw away" the last two decimals?

Because reworking every letter would be really PITA...

All the best,

Herbert
