How to Generate CNC LATHE CODE using solidworks CAM HSMWORKS
In this video, we walk you through the complete process of designing a revolved part in SolidWorks and generating precise CNC codes using SolidWorks CAM for lathe operations. Whether you're a student, engineer, or machinist, this tutorial is designed to help you understand every step of the process, from creating the part to simulating the machining process and exporting G-code for a CNC lathe machine.
What You’ll Learn in This Video:
1. Designing the Part
We start by designing a revolved part in SolidWorks using the Revolve Boss/Base feature. The part includes key features like straight sections, tapers, fillets, and chamfers. This approach is ideal for cylindrical parts commonly machined on CNC lathes.
Key dimensions of the part: Diameter = 62 mm, Length = 90 mm, and additional features like a radius of 10 mm.
2. Setting Up SolidWorks CAM
Learn how to activate and configure SolidWorks CAM to start generating toolpaths.
We show how to define the machine setup, including selecting a 2-axis lathe, setting spindle speed, coolant, and tools.
3. Stock Material Definition
The video covers how to define the stock material (mild steel in this case) and set the correct dimensions for the stock to match the part's requirements.
4. Coordinate System Setup
Setting the coordinate system is critical for proper machining. We demonstrate how to align the Z-axis with the part's centerline and set the X-axis to represent the diameter.
5. Feature Recognition
Discover how to use Automatic Feature Recognition (AFR) to identify machinable features like faces, tapers, and fillets automatically.
Alternatively, we show how to define features manually for precise control over machining operations.
6. Generating Machining Operations
Rough Turning: Using G71 canned cycle for efficient material removal.
Finishing: Achieving the final dimensions and surface finish with G70 finishing passes.
Parting: Creating the final cut to separate the part from the stock.
Additional parameters like depth of cut (2 mm), stock allowances (U = 0.5 mm, W = 0.2 mm), and feed rates (F = 0.3 mm/rev for roughing and F = 0.15 mm/rev for finishing) are highlighted for optimal machining.
7. Toolpath Simulation
See a detailed simulation of the toolpaths in SolidWorks CAM. This helps visualize the machining process, ensuring no collisions or errors occur before generating the final G-code.
8. Post-Processing the Toolpath
We show how to use a post-processor to export the G-code for your CNC lathe machine. The post-processor ensures compatibility with your machine controller (e.g., FANUC, Siemens).
The final G-code includes all necessary commands, such as G71 for roughing, G70 for finishing, spindle speed (S800), coolant (M08), and safe retracts (G00).
9. Verifying and Editing G-Code
We provide tips on verifying the generated G-code to ensure it meets your machine's requirements. If necessary, we demonstrate how to make manual edits for better safety and performance.
