1. ## newbie on gibbscam 2009

Hello all, we recently had some parts spun on a lathe that are 3.500 in diamter and 2.000 long. I work on a 3 axis mill and i am doing a counterbore on the 3.500 diamter. machining the bore thru to center and c-bore is not a problem. what i am hoping to achieve is learning how to chamfer the diameter of my c-bore. I have no problems with programming 45deg chamfers at a stationary z depth but havnt found out how to chamfer this c-bore as it declines down on the 3.500 diamter. We have gibbscam 2009 and im just wondering if theres a way to create the geometry for this part and use a simple toolpath and post which will incorperate the z depth changing as it works the x and y axis when it reaches the lower part of the 3.500 diameter.

any help is greatly appreciated.

2. Do you have the SolidsSurfacer module for Gibbs?

3. Im not exactly sure, i will have to check on monday. Is that module necessary to complete the task i need? If so could i have a brief explanation on how the module works and how i would go abouts doing it? thanks for the reply.

You most likely don't need solids to do what you want, Is Z0 the top of the part, how far down from the top is the start of the counterbore

• the counterbore is 1.500 in diameter and the depth at the highest point from Z0 is .500 deep. so when my chamfer tool starts at X0, Y.750 ,it graduates clockwise so the depth of my z will increase as it works towards X.750, Y0 on the 3.5 diameter.
note: counterbore is machined from center of hole.

If you can post a drawing or photo of the counterbore area that would help,Theres not enough imformation with the 1.5x.5 deep counter bore, to do it,cutter dia is needed as well, But is no problem to do this if you we have all the imformation

• i finished that style of part, now im onto another one with the same application. The OD of the part is 3.485" by 2.140" long, the c-bore diameter is 1.790", and the depth at the highest point is .375". The part is programed from center. Attached is a photo of the part.

Solid Surfacer is not an option as my boss does not have the plugin.

• nothing is attached

• im not sure if the pic was attached right, what is the trick for cutting and pasting a pic, do u have to post the url cuz i tried that and i dont believe it worked properly.

• Key in your message and then scroll down to were it says manage attachments. There you will find the options to upload your files vnc. pdf. jpg. or whatever.

• ahh, i did a quick reply and that wasnt an option ....

try it again..thanks for your patience.

• i forgot to mention im using a 3/8 x 45degree chamfering tool, really just to break the edge by .010 to .020, on a .100 diameter of the cutter as it 45's to a point.
