Research on Ram Thermal Deformation Real-Time Compensation of Large Floor Type Boring-Milling Machine

Abstract:

Ram is a very important component of heavy-duty floor type boring-milling machine, and thermal deformation is a significant source causing errors in machining process. The law of thermal deformation of ram is researched for real-time compensation for thermal deformation error of ram. Meanwhile, DRF function compensation is proposed based on 840D NC system. Real-time error compensator is made and proved to be available by experiment.
