Common Line Cutting
In the Router-CIM Automation job, pick the Advanced Nesting tab and check the Common line box:
The DOIT file needs a knowledge to layer association to cut the common line geometry created by Autonest. You must make a knowledge called COMMONLINE and associate it to a layer called COMMONLINE. This one knowledge will be used to cut all materials in your job.
If you need a different knowledge for each material in your job, you can make a layer / knowledge association formatted like this:
Knowledge name: MATERIAL CODE+COMMONLINE
Layer name: MATERIAL CODE+COMMONLINE
As an example, The ¾ MDF material has a material code of MDF75 and parts on this material will use a knowledge called MDF75COMMONLINE and their common line geometry will be on a layer called MDF75COMMONLINE. The tool radius in this knowledge is used as the offset for part nesting. Other knowledges can cut this layer as well but the common line geometry can only be cut on center and cannot be offset.
Parts in the same job on different materials will need a knowledge / layer association that matches the MATERIAL CODE+COMMONLINE format.
If you have parts on other materials that do not have a knowledge associated with the material code, they will be cut using the regular COMMONLINE knowledge.
The tool diameter in this knowledge is used as the bridge width for part nesting.
Small part cutting can still be used by making a knowledge that has a lower rank than the Common line knowledge and it cuts the SML outside part layer.
