V-Carve Text on a Cylinder | 4-Axis CNC Tutorial in FreeCAD 1.1

Download link for the file created in this video: https://ko-fi.com/s/0162104996 Learn how to V-carve text on a cylinder using FreeCAD 1.1 CAM and a 4-axis CNC machine! In this complete rotary machining workflow, we go step-by-step from modeling the cylinder to engraving wrapped text - generating accurate rotary G-code using only free CAD CAM tools. In this tutorial, you’ll discover how to: Model and prepare a cylinder for rotary machining Create a 4-axis CNC job for milling the cylinder from square stock Set up a 3D Surface operation for rotary toolpaths Optimize parameters for faster machining and smoother finishes Add engraved text that wraps perfectly around the cylinder Generate the V-Carve engraving toolpath for curved surfaces Export ready-to-run G-code for A or B axis machining Whether you’re a beginner exploring rotary CNC or an experienced FreeCAD user expanding into 4th-axis engraving, this tutorial will help you master curved surface toolpaths and text wrapping in FreeCAD CAM. 00:00 4-Axis CNC V-Carving in FreeCAD 1.1 – Complete CAD to G-Code Workflow 01:18 Modeling a Cylinder in FreeCAD Part Workbench for Rotary CNC 02:09 Creating and Scaling 3D Text for V-Carve Engraving 03:28 Explaining the Workflow: Milling the Cylinder First, Then Engraving Text 04:09 Creating the First CNC Job for Roughing and Milling the Cylinder 05:03 Setting the Origin for the Rotary Job to Generate G-Code Correctly 05:30 Adding the Toolbit with Feeds and Speeds for Rotary Milling 06:23 Setting Rapid Speeds for Efficient CNC Movement 06:43 Creating a 3D Surface Operation for Rotary Axis Toolpath Generation 07:40 Changing Drop Cutter Direction to Reduce Milling Time 08:24 Adjusting Depth Offset to Improve Surface Finish on the Cylinder 08:53 How to Simulate a Multi-Pass Operation in FreeCAD CAM 10:20 Exporting the G-Code for Rotary Milling (A-Axis) 10:52 Machining the Cylinder on the 4th Axis CNC 11:32 Creating the Second CNC Job for Engraving Text on the Cylinder 12:54 Pro Tip: Setting the Correct Origin for Rotary Engraving 14:00 Adding the Cylinder Model to the Engraving Job Setup 14:17 Adjusting Position and Orientation of the Cylinder for Accurate Engraving 16:00 Placing and Aligning Text on the Curved Cylinder Surface 17:06 Creating a V-Carve Operation and Generating the Toolpath 17:29 Using “Filter Collinear Lines” to Improve Toolpath Smoothness 18:00 Refining V-Carve Movements: Smoother, More Linear Toolpaths 18:24 Optimizing Up and Down Movements with “Optimized Movements” Setting 18:46 How to Make the V-Carve Toolpath Follow the Curvature of the Cylinder 19:49 Engraving Curved V-Carve Text on the Cylinder – Real 4th Axis CNC Cut 21:57 Final Thoughts and Thanks for Watching Subscribing to my Patreon page means you also have access to this video without interruptions.
