In this post, we are sharing tips on how you can be a better CAD designer specifically when it comes to knives.
We have created a checklist to make sure there are no geometry errors in your file before it is sent to us for cutting. Keep reading for more things you should know when designing and exporting a knife in CAD.
Tips for designing knives in CAD:
Degree of Splines
What to Include
Example of supporting documents and hardware provided with CAD files.
Include design name, dimensions, material, hole diameters, finish thicknesses, surface and edge finishes, secondary operations, quantity, tolerances, and notes.
Another example of a supporting document that we would receive with CAD for lockside handle machining.
Include design name, material, dimensions, hole diameters, tolerances, secondary operations, finish thicknesses, surface and edge finishes, quantity, and notes.
How should my CAD be exported?
In .DXF, .DWG, .STP/ .STEP, or parasolid formats
2D (.dxf, .dwg) is preferred for shape cutting
3D (.stp, .step, parasolid) is ideal for models of folding knife designs and CNC milled components
Name files with identifying design names and material being used.
For anyone looking for free CAD, there is no shortage of examples of "you get what you pay for." Even for experienced CAD designers, free CAD software can be difficult to use. If you are someone new to CAD, this is not a good place to start.
No one wants to waste their time trying to learn a program that may not even produce a machinable file, so send us a template and we can create the file and cut the parts for you.
Here's an example of what you might get from a machine shop that isn't experienced with cutting knives.
