Powermill 4axes for chair

What Will You Learn?

• This course provides a complete, step-by-step guide to programming and machining wooden chairs using Autodesk PowerMill on a 4-Axis CNC Router. Participants will learn how to prepare 3D models, set up machining strategies, and generate accurate G-code to achieve high-quality results in furniture production.

Material Includes

• 1. Introduction to PowerMill and 4-Axis Woodworking
• Overview of PowerMill and its applications in furniture and woodworking.
• Difference between 3-axis and 4-axis machining.
• Practical uses of 4-axis machining in chair production.
• 2. Model Preparation
• Importing designs from CAD software (Rhino – SolidWorks – 3ds Max).
• Orienting, scaling, and positioning models for machining.
• Splitting complex chair models into machinable components.
• 3. Material and Tool Setup
• Defining the wooden stock (MDF, Beech, Oak, etc.).
• Setting up the block for machining.
• Selecting and defining the proper cutting tools for chair components.
• 4. 4-Axis Machine Setup
• Defining workplanes and datums.
• Configuring the rotary axis (4th axis).
• Controlling part rotation for complete machining without manual repositioning.
• 5. Toolpath Strategies
• 2D Roughing: material removal and preparation.
• 3D Finishing: surface finishing with precision.
• Rotary Toolpaths: programming curved and round chair components.
• Special strategies for chair legs, backrests, and armrests.
• 6. Simulation and Verification
• Running full machining simulations.
• Detecting errors, collisions, or gouges.
• Optimizing toolpaths for shorter machining times.
• 7. G-Code Generation
• Setting up the correct Post Processor for 4-axis routers.
• Exporting G-code to the CNC machine.
• Linking the program to the machine and test cutting.
