关于这个项目

我们的原型模型是基于物联网的，因此为它提供了一个可扩展的架构，可以在几乎任何有互联网连接的地方使用它。这是一个 350mm x 350mm CNC，具有 250mm x 240mm 工作区，在开源运动控制软件 (GRBL) 上运行。甚至我们的硬件也大多是开源的，因此主要是削减成本。这台机器完全由本地采购的材料制成，可以加工木材、塑料、硬橡胶、硬树脂等。我们的主要目标是低成本的PCB制造。

对木材的渴望也是有前景的。

作为我们未来项目的一部分，我们也计划添加激光加工支持。

由于该系统目前可以从本地 Intranet 无线控制，我们希望进一步扩展它以制作分布式模型 Web 应用程序，以构建和连接多个此类设备的生态系统。

我们的机器有无限可能。

我们的原型模型的基础框架由 2020 年 T 型槽铝挤压件和 L 型接头制成。该机器通过其 2000 rpm 的直流控制主轴提供大约 80-85 瓦的功率。它具有导螺杆和螺纹杆运动方案，导向光滑杆具有径向凹槽卡扣配合球轴承，可沿所有 3 个轴平稳运行。

最小引线间距为 0.8 毫米/转，每转 2000 步，所有轴的分辨率为 1600。我们的粗机尺寸约为 430x430x330mm，工作区域约为 270x170x65mm，定位精度为 0.04mm。我们的 Z 轴龙门架采用双导杆从头开始 3D 打印。

Z 轴行程 4.8 厘米，安装有主轴钻头。我们使用 45° V 位刀具进行 PCB 雕刻，它还支持 0.2 毫米至 1.8 毫米的立铣刀位。我们为每个轴主驱动器使用最大电流为 3A 的 NEMA 23 步进电机。电机由 2.5A A4988 驱动器驱动，最大微步进分辨率为 1/16，以非常经济的成本为我们提供最高的加工精度。

对于物联网部分，我们可以通过无头显示器（如移动/平板电脑屏幕（此处充当我们的 HMI））从任何具有互联网连接的地方控制 CNC 路由器。我们使用 Raspberry Pi 和连接到互联网的路由器（安全）装置并运行网络服务器来提供用于无线控制我们的 CNC 的接口。我们还计划掌握宝贵的机器部件洞察力，如实时电机扭矩、电流消耗、振动、噪音等，并在网络平台中实时获取洞察力以实现更好的协作。这在制造业中可能被称为工业物联网 （工业 4.0） .
