In general, when utilizing Common Line the nest engine decides which parts will be
common lined. The next section will demonstrate how to utilize common line
within NC Express.
5.7.3 Exercise 2- Common line Nesting
Parts that share the same symmetry are capable of automatically being nested.
Below will demonstrate how to do this.
Before starting this exercise there are two parts that will need to be created. When
setting up the parts use the same material type and thickness.
Step 1: Create a new part. Enable common line within the part properties.
Disable nest rotations for the parts.
Step 2: Import NESTPART1.dxf and save.
Step 3: Autotool the part using only punch tooling around the outside. Set the
parts to be externally microjointed in the four corners. Make sure there are no
microjoints anywhere else but the corners. All tooling will need to match on
each side of the part (symmetry).
Step 4: Save part.
Step 5: Repeat steps 1-4 for NESTPART2.dxf
Once parts are created they are ready to be common line nested. The following
is the process of creating a common line nest automatically.
Step 1: Create a new nest by going to File menu | New – Nest, enter run
number 110 and also select the same material type and thickness used to create
the two parts- NESTPART1.cp and NESTPART2.cp.
Step 2: Go to the Part List and schedule both of the common line parts to be
nested. For NESTPART1.cp enter a quantity of 28 and for NESTPART2.cp
enter a quantity of 10.
Step 3: Utilize a plate size of 100”x50” (2500mmx1250mm) to nest the parts.
Step 4: Global parameters.
a. Enter part separation equal of tooling that was used on the outside
of the parts. (Ex. 0.25”x3.00” tool used on the top and bottom Y-
0.25” & 0.125”x1.50” tool used on sides X- 0.125”)
b. Set Nest Direction to- Top left
c. Enable Common line- Same part only
Note- Notice that when common line is activated in the nest dialog some
options are unavailable. This is because the nest environment has now changed
to grid nesting only. Parts are nested symmetrically, and if parts are not
symmetrical they are nested in a grid pattern.
Step 5: Click OK to nest parts.
