Abstract
In this paper, the influence of thermal accumulation on the deposition trajectory quality during the plasma deposition process was investigated. The energy balance model in the deposition process was analyzed and an adaptive gas cooling subsystem to diminish thermal accumulation during manufacturing process was developed. The subsystem consisted of gas cooling rotation device driven by step motor and a special CAM program. Experiments were carried out to verify the validity of the adaptive gas cooling subsystem. Results showed that the application of adaptive gas cooling subsystem effectively suppressed the thermal accumulation during the manufacturing process and eliminated the collapsing of the deposition trajectory.
