Does anyone know if it is possible to generate 2D toolpath in CamWorks only off a Solidworks sketch instead of making a 3D model?
Yes it is possible but it cannot be extracted automatically. You must define it manually.
When you define the depth it must be greater than zero. So in reality the tool-path is still 2.5 axis but driven from a sketch.
Define the feature manually by selecting a sketch.
Thank you so much for the quick reply. I may have a couple more simple questions but I will certainly give it a try thank you for your help
I have been playing some with toolpaths using sketches only. One thing I am struggling to understand is orienting the cutter or probably more than anything orienting the Z. My cutter is always coming from the bottom. Do I need a point or line that defines the Z direction in my sketch?
The Z direction is controlled by the setup. (This is the same as using a 3d part.) So when using a 3d part we click on a face for the setup. You, because of using sketches, will have to define a setup using planes. Then when defining the setup you will see an arrow for the Z direction. Press the double arrow to toggle the direction of Z. This will allow you to flip it
Got it! Thank you for your help.
Do you have any tutorial video for generating NC program for 2D Sketch in SolidWorks CAM?
I will create a quick video shortly. It works like regular programming. All you need to define is the stock based on a sketch for it to calculate correctly.
Please use the link below to see a video on 2D programming with SOLIDWORKS CAM. This method would be the same for milling or 2D cutting. The video shows an example I use on my GoFabCNC plasma table.
Below is a video showing the automation benefits of using a 2d to 3d approach for programming. Either way will work but, I wanted to share the differences. I run the 2d to 3d most of the time on my plasma and did this in production years ago on a laser using CAMWorks. (Before SW CAM existed)
2d to 3d - Fabrication programming
I have gone through the video. It's really great work. I tried the same, but i have a doubt. How to define PLASMA in 2.5 feature parameter? Because with respect to PLASMA strategy only, you are setting an operation. How to define that (like waterjet, plasma, laser machining). For a reference I attached an image.
I have created a quick video to show the process I use when automating SOLIDWORKS CAM. Please take a look and let us know if you have questions.
