Abstract

PURPOSE:To improve machining efficiency and machining accuracy by computing machining condition command in which cutting efficiency becomes optimum successively with progress of machining and by performing machining following to the change in machining condition. CONSTITUTION:When machining information is input in an input device, a tool transfer position is computed from the machining information such as the input machining objective shape, shape machined, tool shape used, machining method. And machining condition is computed from the input information and cutting constant. As the machining condition, feeding value which keeps efficiency optimum following to cutting load changed according to the tool position and cutting speed can be considered. And machining condition command is determined by the computed machining condition, and the command is output with the tool transfer command. This process is repeated until judgement of processing finish to the machining objective shape is given. Then, machining time can be shortened, and better machining face can be obtained and machining accuracy is improved.
