Abstract: B2016 Frame Planer was reformed in CNC based on the FX2N PLC Mitsubishi. Frame planer tool set, crossbeam external interface and main cutting motion electrical control circuits were designed. The control system of main cutting motion, tool set, and crossbeam was programmed. The logic sequence control over the tool set, crossbeam and the work bed was realized. The machine performance and machining ability  were greatly improved using the alteration machine. The manufacture precision and efficiency were increased, and large economical benefit was produced.
Key words: frame planer; programmable logic controller （PLC）; numerical reform
