tips on backside deburring?

[CuttingEdgeManufacturing]

Hey all,

just thinking about purchasing a backside deburring tool from harvey. kinda got it modelled up in the tool library in F360, doesnt quite match up i think, but also just looking for a quick video on programming the backside chamfer. or just general tips and issues others have had, so i can avoid it myself.

Double angle deburring tool, or an actual dedicated backside deburr tool?

If the former, I found that I can tweak a Chamfer tool settings to closely resemble my tool. Using a combination of negative Stock to Leave and other various settings, I'm able to get darn close to what I need. I then save that as a Template and never think about it again. The CAM Simulation here is quite valuable.
For the latter type of tool, I'd suggest going with a Form tool

you got a link to the double angle tool? or any recommedations? i didnt really see a double angle chamfer tool on my catalog for harvey.

i suggest doing a 45 since the math is simple. i use 2d contour and just drop the counter you want evenly with the stock to leave. ( bottom counter .05 lower, and then -.05 radial stock to leave) add your desired chamfer to the -.025.)

i would creep it in over a few trial runs.

dont forget to make your lead in and out appropriate as well.

I program this the same way i do ID grooves in the Mathe when i cant use my ID groover.

I use a double-sided tool, defined as a form tool AND a regular chamfering-tool.
Since form-tools only can be used with a limited selection of operations. So even if you make a simple 90 degree point its no 2d chamfer for you 😉

Simple solution for making stuff easy for me was to use the form-tool when backchamfering  and a chamfertool with the same diameter for everything else
