We made presetting blocks for the different machines. We use an Indexer on most of the machines and the rotary indexer center height is different on every machine. So we set our tools there and the program for machining is figured from the center of the part. We started out programming from the top of the stock but if a tool breaks and the part is no longer round there is no way to set it because the reference surface is gone. A tool setting block was the only answer. |
