Hello

Nice job  ;D

I found some errors with the figures #

page 6:

The geometry is shown in Figure 2 as a cross section view of one edge of a section of inlay.

It is figure 4

page 7:

The key to understanding how it work is shown in Figure 3. Here we have a letter “A” processed with the V-Engrave MOP.

it is figure 5

page 8

For the substrate: create a series of enclosed shapes, using the drawn pattern as a reference, on the inside of the pattern to allow the Vee cutter to create the required sloping edges on the inside of the pattern. This can be done by creating offset shapes. The width of the offset is shown as Os in Figure 2.
• For the inlay: create a series of enclosed shapes, using the mirrored pattern as a reference, on the outside of the pattern that allows the Vee cutter to create the required sloping edges on the outside of the pattern. This is done also using the offset capability in CamBam. The width of this offset is shown as Oi in Figure 2.


it is figure 4

page 9

A number of examples are shown in Figure 7:

it is figure 8

page 11

With the V-Engrave Regions defined the next steps are:
• For the substrate: create a pocket MOP to machine out the remaining material in the inside of the V-Engrave paths. This can be done by using the original geometry and specifying a substrate roughing clearance in the MOP so that the cutter will stay away from the edge by this amount so that it only cuts up to the centre (or close to it) of the V-Engrave path way. This roughing offset is computed as shown in Figure 4.
• For the inlay: create a pocket MOP to machine out the remaining material outside the V-Engrave paths and inside the outer border of the item being made. A pocket MOP is created for these shapes by specifying a roughing clearance for the inlay roughing clearance as also computed in Figure 4.


it is figure 7

page 13

Not sure to understand.

a) Substrate V-Engrave:

i) Create a new MOP and name it “1-substrate engrave”
ii) Select all the shapes in Layer 1, excluding the outer boundary.
iii) Create a new MOP using V-Engrave and set these computed substrate parameters:
  (1) Stock surface
  (2) Vee cutter angle


a new MOP or a new Part ? (same for b,c, d)

Dear David

Many thanks for identifying the errors in the text.  I am attaching a revised version of the notes.  Hopefully I have fixed all of them.

To EddyCurrent: I am attaching the updated sources for your records.
