Automating PowerMill with C# API | Step-by-Step Guide

In this video, I present an API I developed from scratch to automate programming tasks inside Autodesk PowerMill. This API was designed to help CAM programmers save time, reduce repetitive work, and create a more efficient workflow. I’ll walk you step by step through the process: importing models, creating workplanes, setting machining parameters, importing tools, generating toolpaths, checking for collisions, and running simulations. Although I’m using PowerMill as the example, the same automation logic can be applied to other platforms like NX, Fusion 360, and Mastercam. The goal is to show how an API can transform complex CAM workflows into a faster, more reliable, and customizable process. Whether you’re a CAM programmer, a manufacturing engineer, or simply curious about automation with C# and APIs, this video will give you insights into what’s possible when software development meets digital manufacturing. ⏱️ Chapters 0:00 – Introduction 0:45 – What is this API? 2:00 – Importing the model 4:30 – Creating Workplanes & setups 7:00 – Tool import & management 10:20 – Generating toolpaths automatically 14:00 – Batch calculation & collision checks 18:00 – Simulation & validation 20:30 – Final thoughts & next steps 🔧 Software shown: Autodesk PowerMill 💻 Development language: C# API 🎯 Topic: CAD/CAM Automation If you find this content useful, don’t forget to like 👍, share 🔗, and subscribe 🔔 for more videos on CAM automation, PowerMill, NX, Fusion, and beyond.
