If you are in the jewelry manufacturing business or learning CAD for design, you have likely heard the name Surfmill. Developed by JD (JewelCAD) or more specifically, the Beijing Jingdiao Group, Surfmill is a powerhouse in the world of 3D relief design and CNC machining.
With the release of Surfmill 9.5 (often confused in search queries as Surfmill 95), the software has introduced significant upgrades in speed and user interface. But with professional software comes a professional price tag, leading many to search for a "free" version.
Here is a complete look at Surfmill 9.5, its features, and the safety of obtaining it.
Assumptions: 20-year life, 3% discount rate, O&M = $8,000/year.
LCOE = (Capital + Σ O&M/(1+r)^t) / Σ AEP/(1+r)^t = $0.09/kWh.

If the official site only lists newer versions (SurfMill 8.0 or 10.0), check CNC hobby forums like CNCZone or Practical Machinist. Often, community members share direct links to legacy 9.5 installers provided by Jingdiao tech support.
FreeCAD is open-source. Its "Path Workbench" is essentially a free CAM module similar to SurfMill's 2.5D and basic 3D strategies.
Let us assume you successfully downloaded the official free trial of SurfMill 9.5. Here is a 30-minute workout to test its power before the trial ends.
Step 1: Import a Model
Launch SurfMill 95. Go to File > Import > 3D Model. Use the provided sample STL or STEP file (often included in C:\Program Files\Jingdiao\Samples\). If you are in the jewelry manufacturing business
Step 2: Define Stock Click "Stock Modeling." Set your material size (e.g., 100x100x20mm aluminum).
Step 3: Create a Tool
Go to Tool Library. Create a new tool: End Mill, 6mm diameter, 2 flutes. Set speeds (10,000 RPM, 800 mm/min feed).
Step 4: Generate Roughing Path
Use 2.5 Axis > Pocketing or 3 Axis > Z-Level Roughing. Click "Calculate." Watch the blue toolpath appear.
Step 5: Simulation Click the "Virtual Machine" button. Watch the tool cut away the virtual stock. This is where SurfMill shines—the realism is excellent. Assumptions: 20-year life, 3% discount rate, O&M =
Step 6: (If Trial allows) Post Processing
If your trial permits output, go to Post Process. Select your machine (e.g., "Jingdiao CNC" or "Fanuc"). Click "Save NC File."
| Metric | Value | |--------|-------| | Average pneumatic power | 112 kW (peak 95 kW electrical after losses) | | Annual energy production (AEP) | 312 MWh (assuming 80% availability) | | Capture width ratio | 0.38 | | Peak-to-average power ratio | 3.2:1 |
The device achieves rated power at ( H_s = 2.1 ) m. Below 0.8 m, the turbine does not self-start; a small auxiliary motor (2 kW) can be used for grid synchronization.
