Processing Temperature Fluctuation of CMC
Fenómeno do problema
Temperature fluctuates ±5-8°C during CMC processing, exceeding the ±2°C control accuracy
Análise das causas
Improper PID parameters of the temperature control system; aging heater bands with uneven power; improper thermocouple position causing measurement deviation
Solução
1)Re-tune PID parameters; 2)Replace aging heater bands; 3)Adjust thermocouple position to the melt pool center
Conclusão principal
Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are the key
