Cutting Profiles with BobCAD-CAM

Profile cutting is so common almost any 2D part you machine requires this type of tool path. From finishing the wall of a pocket to cutting around the outside shape of a part, profiling is essential.
We offer 3 types of profile options that accommodate for different profiling needs. These options can be found under patterns of the Mill 2 Axis Wizard

Standard:
Our standard profile cuttings allow for a rough and finish tool, stock for finish, lead in / out options and step down in z. This is the most common profile cutting tool path.

Contour Ramping:
This option allows you to ramp the tool around any profile. Common uses are for helical milling & slot milling. You control the angle of cut or a step down distance.

Side Roughing:
Allow you to walk the tool in to a profile. Works best where you have more stock to cut then the cutter can take on a single pass.

With all profile cutting features you have compensation options, Allowing BobCAD to offset for the cutter, or to call cutter comp (G41 G42). These compensation options allow for wear comp, cutter comp, and center line cutting.

Using our profile tool path you can cut slots, shoulders, letters, holes, filets, t slots, dove tails, form shapes and other common every day 2D milling features.


If you have any questions please let me know.

Hello Everyone,

I have come to this community to learn about everyone's CAD CAM programming needs, and to shed some light on using BobCAD.  If there are any topics you would like covered just ask.

Thanks

How to use the software:

This video walks through the steps of opening a DXF file and moving the part to zero.

This video walks you through the steps of cleaning up geometry and using layers to organize your part.

This video walks you through the steps of drilling and tapping the holes for this sample drawing.

This video walks you through the steps of cutting the slots for this drawing. We are using the profile feature and contour ramping, which will ramp down to cut the slot out.

This video walks through the steps of cutting the pockets. I show how you can use top of job to change where the tool starts cutting from. Using top of part settings is great for when you are cutting a pocket inside a pocket. This way you don’t cut air.

This video walks through the steps of cleaning up the walls of the pockets. I use the profile feature with side roughing. This allows the tool to walk into the wall and clear any extra stock that might have been left over.

This video walks through the steps of simulating your program and posting code.

Question: If my simulation show the tools cutting in the wrong order, how do I change that?

Answer: The machining order can be set to ” individual tool ” or ” individual Feature”

Question: Why does the software call more than one tool when drilling a hole. What if I only want to call a drill, instead of a center drill, a drill and a chamfer tool?

Answer: We use tool patters to optimize hole making processes. The idea is to call and program all the tools need to make the kind of hole you want to make. You can customize the patters to fit your needs. Watch this video to learn how: http://screencast.com/t/0vkwZ8WgFd
