在等离子喷涂快速制造金属模具工艺中，采用机器人等离子喷涂成形工艺，在被喷涂原型表面生成具有较高硬度的耐磨金属涂层，机器人喷涂路径规划是影响金属涂层成形性的关键因素。而轨迹间距是机器人喷涂路径中的重要参数。通过对机器人等离子喷涂几何模型的实验研究，从而确定了最佳的轨迹间距，为合理的机器人喷涂路径规划提供了依据。

英文摘要：

In the plasma spray rapid metal tooling, the wearable metal film with high hardness is formed on the sprayed prototype by robotic plasma spraying. The robotic path planning is the key that affects the formability of the metal film. And the path interval is one of the important parameters of the robotic path. The geometry model of the robotic plasma spray is experimented to confirm the optimal path interval, which can afford evidence for the reasonable path planning of the robotic plasma spraying.
