As with other casting design characteristics, the machining allowance depends on ____.
A) the casting process
B) the number of fillets and rounds used
C) the type of material used
D) both a and c
E) none of the above

Question

Quizplus · Accepted Answer

The machining allowance depends on both the casting process and the type of material used. Different casting processes may result in different surface finishes and tolerances, which will affect the amount of machining required. Similarly, different materials may have different characteristics that affect machinability, such as hardness and abrasiveness. Therefore, the machining allowance must be determined based on these factors. The number of fillets and rounds used may also affect the amount of machining required, but it is not the primary factor driving the machining allowance.
