2D Adaptive Clearing Question

I need to clear an area around a cylinder on a stock that is a cylinder. I select the top rim of the cylinder I want to clear and the surface I want to clear down to. I have a couple of questions where I don't think I am getting it.

 

1. Using a .75 Shearhog to clear the material. The default cut was enormous, .3. I am wondering if I am just assuming too much on the ability of the software to know this is too much. I can get the behavior I want by modifying the Optimal Load parameter in the Passes tab.

2. Is there anyway to have this operation ramp down slowly? Meaning, I could take the larger single cut towards the center, but ramp the clearing down slowly and around the cylinder.

 

Relatively new to this and thinking I am missing something. Thanks in advance for any pointers.

1) The default value is simply a calculate based on cutter size. If you make a new toolpath and hold the Shift key while hovering the mouse over the Optimal Load field you will see the expression used to calculate the stepover (for that one the default is tool_diameter*0.4). This works all over the place and there are some very clever things you can do with expressions in the CAM.

 

2) Without seeing your current toolpath (and settings) it's a little difficult to make recommendations, but with the current information no, I don't believe 2D Adaptive will make the toolpath you're thinking about. You can make it cut from the outside but it will still be a constant depth cut, either in one step or multiple steps, with no ramping. The exception is the helix in if the tool starts in the center of the stock which is defined in the Linking Tab as far as angle of entry, minimum and maximum diameter, and entry angle (think a helical cone).

Thanks, really appreciate the input.

 

1. That is what I was thinking. Since I am new to this, I think I am overestimating the "smarts" of the program and how much I need to know/control. (no dig on Fusion, just a realization). Basically, I was hoping I would not need to know as much about machining as it turns out I am going to have to.

 

2. Thanks again. I was comparing the toolpath from SprutCam and its adaptive clearing. Not a big deal, but the ramping feature is pretty interesting.

 

Thanks again!
