CAD-CAM technology is the modern solution to CNC machining automation. Can your machine shop benefit from CAD-CAM? More often than ever before machine shops are using multiple CNC programming systems than ever before. The reason is simple. Not many CAD-CAM products do it all and small to mid-sized machine shops can benefit from having a primary system with a supporting cast of programming solutions in order to meet all of their programming needs. How can BobCAD-CAM fit the bill as your primary CAD-CAM solution?

In this example we are going to use a bmp file of a fish to:
• Get the profiles of the fish to use for the embossing process
• Use the image of the fish for texture

During the layout process we are going to use the following features:
• Load Image
• Rectangle
• Change image origin
• Line join
• Ellipse
• Spline fitted
• Deform contour
• Add new layer
• Offset
• Quick trim
• Arc sketch
• Line continuous

Getting Started:

Step 1: Draw a rectangle 11” X 6”
Step 2: Draw a center line
Step 3: Draw an ellipse 9.95” X 5”
Step 4: Load Fish BMP
Step 5: Change the origin of the image to X: .95” Y: 1.25” Z: 0.0”

Now we are going to trace the body and fins of the fish:

Step 6: Add a new layer and make it active
Step 7: Use a fit spline to trace around the body of the fish
Step 8: Add a new layer and make it active
Step 9: Use fit spline & line continuous to trace around the fins of the fish.

Now we are going to trace the gills and eye of the fish:

Step 10: Create a new layer and make it active
Step 11: Use the fit spline to create the gills
Step 12: Use arc sketch to create the eye

Congratulations you have completed all the wire fame layout for this part!

The steps we will be taking now is for the emboss model, we are going to use the wire frame we created to raise and lower areas of our emboss model

Step 1: Create/ Modify stock X:11” Y:6”
Step 2: Emboss convex ellipse subtract the ellipse
Step 3: Emboss convex ellipse add the fish body
Step 4: Emboss convex ellipse merge high the fins
Step 5: Emboss line subtract the gills
Step 6: Emboss convex art the eye

Note: If you see a red X in the BobART manager it means that you have not “regenerated” the emboss model. To do this you RT click on emboss model and LT click on regenerate.

Let’s create our emboss model:

Step 7: Regenerate your emboss model
Step 8: Texture from Image
Step 9: Create a boundary for the image texture
Step 10: Smoothing
