Thanks for answers. I can use stock at lathe but I can't use stock at milling. Can you send me example? days days I am working on this work but I cant

I load the main part file and I go machine type->MILL->mill3axis vmc mm.mmd then I go toolpaths->surface rough->flowline I select boss I select drive surfaces on part I go stock setup in stock setup->shape->file I select "file" that "stock.STL" I write essential parameter about tool-ballnose tool 5mm diameter I regenerate all operation. toolpaths appears. Toolpaths start top of part not top of the stock. I hope I can tell my problem ) I cant write very well Tool is cutting air mastercam mill cant see stock. can you help? thanks

I want to make milling. At milling, tool doesnt start top of stock, does it?

Using STL file in mastercam and Define stock At Rough Flowline Hi, I am using mastercamX. I want to machine to cast iron. At Rough Flowline operation I cant define stock. I am writing stock parameters but Mastercam didn't use stock. Tool must starts operations top of stocks, but tool starts operations top of part. How can define stock? And I want to define stock with stl file. I can load stl file but mastercam doesnt use this stock. Tool starts operation top of part. I want to machine to cast iron. I must define amorph shape stock. And mastercam must use this stock. How can I do? Thank you very much. MastercamX (10.0.12.2)
