Stop Using the Wrong Boundary in PowerMill! (User vs Selected Surface)

Are you making costly mistakes with your CNC machining boundaries? In this PowerMill tutorial, we compare the Selected Surface Boundary vs User-Defined Boundary to show you why using the wrong boundary ruins adjacent faces and fails your finish machining. Discover the exact differences between User-Defined and Selected Surface boundaries in Autodesk PowerMill. Learn when to use each boundary type safely, how to prevent tool gouging on neighboring surfaces, and why User-Defined boundaries are strictly for roughing operations—not finishing! ⏱️ Timestamps: 0:00 - General Video Overview 0:15 - Explaining the Differences Between the Two Boundaries 1:10 - Additional Explanations 1:30 - Use Cases for User-Defined Boundary 2:18 - Next Video Preview 🔔 Don't forget to Like, Subscribe, and Comment your questions below! 👉 Check out my full MTD File Playlist here: [   • MTD File Creation Workshop – 3‑Axis Machin...  ] #PowerMill #CNCMachining #PowerMillTutorial #CADCAM #AutodeskPowerMill #MachiningTips #CNCProgramming #Boundary #Selected surface Boundary # user defined boundary # MechMasterAcademy
