I have the attached solidworks model in which I'm wanting to mill out a pocket with a chamfered edge and radius's.
The angle of the chamfer and radius is important.
What would be the best way to do this? 2D or 3D milling? If so, how would I go about setting up the cutting options. Also, would a bull nose end mill be the correct way to a get a smooth chamfer and radius? Can cambam support these end mills?
I've attached a cb file that shows one way to make the item in CamBam, it was created using CamBam v1.0
It uses a variety of machining operations, spiral drill, 3D waterline, pocket, profile, all chosen to speed up the job.
For example there is no need to mill out the centre flat section using a 3D opration when a 2D pocket will do.
CamBam can use a bull nose but for 3D operations a ball nose is recommended.
Some of the parameters will need to be changed to suit your machine, material & tooling and you may want to reduce depth of cut, stepover, or the finishing tool diamter if the finish is not smooth enough
Sorry on the delayed reply. I've been working out on site for a few days.
Thanks for your cambam file, much appreciated! I've milled out the pocket after adjusting a few parameters. I had to change the tool diameter to 10mm bull nose for the first 3D machining operation as I don't have anything smaller. But in doing this the target depth isn't achieved for some reason. Its cut down to about 4-5mm depth instead of going down to the specified 7mm. Is there a perimeter I need to adjust to allow machining of the full target depth using a 10mm bit?
Ps. Used this forum as I couldn't access the official CamBam site for some reason. Seems to be back up now.
You have to change the "Boundary Margin" parameter, it is related to the tool diameter. Start with a number equal to tool radius then make it bigger if that is not enough.
