Tabs and Flash

First step is to separate all of the parts from the sheets they were machined from and  remove the tabs and flash, if any.
What are Tabs and Flash?
Tabs: In order to keep the parts in position while they are being machined small tabs, typically .04 thick and about .25 long, are left in place to prevent the cutting bit from throwing what would otherwise be loose parts around the room.
Flash: The name is taken from plastic PC models which typically have "Molding Flash". Caused if the molds the parts were made from didn't fit together precisely, small amounts of thin plastic would be present along the joints. The same thing happens to the parts I cut if the cutter doesn't go all the way threw the material. Can be caused by minor differences in material thickness or the cutting surface not being held flat.
