NUMERICAL CONTROL INFORMATION GENERATING APPARATUS

A numerical control information generating apparatus has a function of automatically correcting machining conditions by calculating corrected machining conditions from corrected numerical control information. The apparatus also has a valid/invalid setting function of automatically correcting machining conditions for the purpose of allowing an operator to select at will the conditions under which the function of automatically correcting machining condition works, and a numerical control information correcting section, in which a machining conditions automatic correction command is provided, so as to perform machining conditions automatic correction at any time as required. As a result, since machining conditions are corrected automatically by correcting numerical control information, an operator can set proper machining conditions easily even if the operator does not understand the relationship between the machining conditions and the generated numericaL control information.
