My employer is expecting my replacement to learn CNC programming for a Haas VMC in the 3 weeks notice I have provided them. My "replacement" has less than 6 months experience in machining of ANY kind. He is very intelligent and a fast learner, however, I need to make my employer understand his expectation level is way too high.
Would several of you who are experienced CNC programmers for similar equipment provide some feedback on how long is reasonable to learn basic cnc programming (edits of existing programs and very basic work), mid-level (writing basic programs, advanced edits, etc.) and advanced programming. I am attempting to stave off disaster with an employer who does not know programming himself and underestimates the time required for proficiency. Thank you in advance to all who offer advise!
