The inner workings of the tools in different modes of operation. 4. The function of the different elements of the press and tools. 5. The effects of changing fill and upper and lower compression points. 6. Actual observation of die wall friction and die wear. 7. Observation of "spring-back" and "pop-out" as it happens. 8.
