Apparatus and method for aiding programming

摘要

An apparatus for aiding a machinist in preparing a machining program. A machining simulator (11) simulates a basic machining program. Values of machining variables (HJ) are obtained during the simulation and stored in a simulation result data memory (12a). A spindle load determiner (41), a cutting speed determiner (42), and a rotating speed determiner (50) analyze the machining variable values (HJ) of a certain machining process to determine the machining efficiency of that process. A navigation information memory (47) stores a plurality of messages (MSG) for giving advice on how to change the cutting conditions. A message, which depends on the analysis of the machining variable values (HJ), is selected from the memory (47) and is shown on a display (6). Accordingly, an operator can easily modify the basic machining program by following the message on the display (6), even if the operator does not have much knowledge or experience.
