Summary of Video “fresadora01”
This video is a detailed tutorial and walkthrough on using SolidWorksCAM for CNC milling programming. It focuses on a rebar cutter piece featuring multiple elements such as pockets (open and closed), holes, and rebates. The tutorial covers key technological concepts and product features essential for effective CNC programming.
Key Technological Concepts & Features
-
SolidWorksCAM Add-in Activation Instructions on enabling the SolidWorksCAM add-in within SolidWorks, including managing loading times and adjusting language settings.
-
Machine Definition Selecting the appropriate CNC machine type, including 3-axis, 4-axis, 5-axis milling machines, and lathe options. The tutorial primarily uses a 3-axis milling machine for simplicity.
-
Tool Management Overview of cutting tools available in the turret/tool library, such as:
- Flat tools (6mm, 10mm, 16mm, 20mm)
- Centering tools
- Drill bits
- Spherical and toroidal tools
- Boring tools
- Countersinks
- Face milling cutters
- Probing tools
Explanation of tool dimensions (diameter, working length, total length) and their applications.
- Material Selection
Defining the initial stock/block material, with examples including:
- 6061-T6 aluminum alloy
- Low-carbon steel
- Stainless steel
- Cast iron
- Tool steel
- Polymers
- Nickel alloys
The material choice impacts cutting parameters.
-
Initial Stock Definition Setting the size of the initial block larger than the final part, especially increasing the Z height to allow for machining allowance.
-
Work Plan Definition Selecting the face of the part to work on and orienting the tool approach direction. Adjusting and defining the coordinate system based on the part’s geometry and machining setup.
-
Feature Recognition & Definition Identification and programming of various machining features, including:
- Planar (facing) features to remove material on flat surfaces
- Rebates (rectangular pockets) with islands (areas not to be machined)
- Mortises (irregular pockets)
- Hole features of different sizes requiring different tools
-
Machining Operations Assignment Assigning appropriate machining operations to each feature, such as:
- Roughing
- Contouring
- Facing
- Drilling
- Centering
Tool selection is based on feature size and type. The tutorial also covers adding new tools (e.g., 20mm and 14mm drill bits) if not available in the library.
-
Toolpath Generation Generating toolpaths for each operation and visualizing them in the operations tree.
-
Simulation Running step-by-step or full simulation of toolpaths to visualize machining sequences and verify material removal. The video explains color-coded difference analysis between desired and obtained geometry:
- Green: Finished surface (no further machining needed)
- Blue shades: Areas needing more material removal
- Yellow to red: Over-machined areas (material removed excessively)
-
Post-Processing Generating CNC G-code from the work plan, including:
- Saving the output file
- Overview of G-code content such as tool changes, spindle speeds, feed rates, and movement commands
Guide/Tutorial Highlights
