The advantages of noses include:
- Having consistent engraving depth is the major plus and a convenient location for a chip removal.
- An advantage that’s not always obvious is the pressure a nose exerts steadies the material and makes the material stick better to the table.
- A well-leveled table can engrave without a nose, provided the material you are engraving is a consistent thickness, but itsnot a simple task to achieve with all the possible irregularities in table flatness, material thickness, and adhesion to the table.
For a nose to work best: Use a chip removal system, the spindle must have over-travel capability, the software must apply over-travel, and most importantly, make sure the cutter is properly set.
