Standard Radius sizes
Standard Radius sizes
(OP)
I am wondering if anyone has a resource for Standard radius callouts.
That is, I would like to specify a radius diameter for inside cuts of a plate for example (lightening holes) to enable the cutter to use the same drill bit for cost effectiveness.
Does anyone know where can access this information?

RE: Standard Radius sizes
Also if you are looking to CNC machine these a radius bigger than the cutter is best as you then have a cutter path and it does not “slam” into the corners.
RE: Standard Radius sizes
its somewhat square, and the cut is somewhat square as well... a fillet on the order of .100 on the inside of the lightening cut, give or take, looks ok from a design standpoint.
so should i specify .12 min as the dimension? (1/8 drill)
again, im after low cost, ease of manufacturabilty here.

this way if it cuts in excess of .25, itll be ok?

RE: Standard Radius sizes
Your standard radius probably should be bigger than the machinist's cutter. If they are writing a CNC program to fabricate your part, they do not want to pause the cutting tool. They want to move the tool around in an arc at a constant velocity.
If I want them to use a 1/2" cutter, I specify a radius of 0.35".
If they are machining on a manual mill, then the radius is your cutter's radius.
