摘要

目前金属增材制造设备大都建立在大型数控机床系统的基础上

用户很难根据不同需求和功能进行合理的修改和二次开发。根据数控加工技术的基本原理

开发了一套以智能运动控制卡为运动控制核心、以等离子弧为热源的一体化增材制造设备

通过三维建模、切片处理、路径编译、焊枪运动、步进送丝等步骤具体实现。制造过程可通过上位机实时控制

提高了加工柔性。整套设备实现了由三维模型到实体零件的自动化成型。经测试

设备性能良好、制造过程稳定、加工周期短

加工的零件性能良好。

Abstract

Currently

metal additive manufacturing equipment is mostly built on the basis of large-scale CNC machine. It is difficult for users to make reasonable change and secondary development according to different practical needs and functions. A set of integrated additive manufacturing equipment is developed based on the basic principles of CNC machining technology. This equipment uses intelligent motion control card to control the motion path and uses plasma arc as heat resource to melt the metal material. The manufacturing procedure includes three-dimensional modeling

model-slicing processing

manufacturing path compiling

welding gun moving control and stepping wire feed. A real-time control of manufacturing process is achieved by a host computer so that the process flexibility improves. Thus

this equipment is able to automatically accomplish the whole procedure from three-dimensional model to formed part. After testing

this equipment has the advantages of high performance

stable manufacturing process

short process cycle and high performance of formed parts.
