How are the production times for a material in electron beam machining

1.	How are the production times for a material in electron beam machining?(a) Very small(b) Small(c) Moderate(d) LongI have been asked this question in an interview for internship.The origin of the question is EBM-Applications, Advantages and Disadvantages topic in chapter Thermal Processes of Advanced Machining
Answer» Right option is (d) Long The best explanation: In ELECTRON beam MACHINING, long PRODUCTION times are REQUIRED due to the GENERATION of vacuum in the chamber for machining purpose.
