I took a look at the file. Have made a few examples for you to look at.Can not access the FTP site for some reason. Will try in the morning. I can E-mail it, but it's about a meg big.

Send your file on over, need to see what you are trying to do

Use the help function, it does a pretty good job of explaining what needs to be Done to create a custom tool for lathe

I have an onsite class today, has a whole shop full of Kia's. I will ask.

What is the Finish requirement? Is it below a 12? How hard is hard 48Rc,58Rc? If it hard enough and your lathe is rigid, try CBN. If it is not hard enough, turn to a Ceramic. A chemical reraction will occur if the Rc drops below 50 to 52 Rc.(that where the ceramic comes in)

C axis Cross Contour Cross contour creates a toolpath parallel to the axis of rotation and is used primarily to cut slots. Mastercam uses the entire chain to set the tool plane (Tplane) and construction plane (Cplane) so that the tool is placed perpendicular to the axis of rotation for each toolpath you create. Choosing this toolpath also turns off cutter compensation so that the center of the tool follows the programmed contour. It is important where you pick, and on what geometry first for the cutting order. Remember, this toolpath sets the tool plane automatically. So in the order you pick geometry that’s where Mastercam will start the toolpath. Meaning: if the geometry you pick lies on a 60 degree angle from the side view, it will rotate the “C” axis and start the toolpath from there. Hope this helps

I have a Hicell 23II, I have ran some pretty complex work pieces on that machine. Mastercam has pushed the code all the way. C,and Y axis,surface milling, circle toolpaths,thread milling, rotary paths,roll die, what ever.

Send it on, I'll look at it

Just a sample for right now.I can give you the outline of the pojects if you like and more information.

No problem, it is definitly different. I can send a sample of face polar(Z axis) and X axis with Y motion. I am finishing up a project book for Ver X that covers Millturn applications using C,Y and Rotary for the Lathes. Do I use the E-mail address from your profile?

Ver 9 or Ver X?

If you are using a new WCS for each operation,it should be showing all operations in verify with one stock definition.Set your stock for the first operation and Verify. Now if you create a new toolpath with a new WCS or toolplane and the stock setting goes south, just open the stock set-up folder and close it back up. You do not have to change anything, just re up-date the stock set-up. It Should put the stock back to the first setting. When ever I have Lathe and mill toolpaths in the same file with different Machine definitions and I want to use the lathe verify for the milling tool paths, Thats what I do.

Can you just draw the helix and then Un-roll it?

Look for Type "Os" in the program ,open brackets, odd symbols

Any one having trouble applying toolpaths to Read only files? I was doing some training the other day and was having my students bringing in files from the CD rom. The files come in all right but when any toolpaths are applied we all recived a "Incorrect parameter" message. From there When trying to exit the program it would give another message "You cannot close the applicationwhile a task is active" Then it is CTRL-ALT-DEL. It has done this on several systems. These are .mcx files running the Lathe. Copy them to the hard drive and everthing works great.

Well, the one's that worked in Ver 9 will not even run in Ver X. I'll keep in mind the radius on the corner.Thanks for the tip. I am going to send in the files back east today

Any one have Issues with verify of Custom tools in lathe? Have some Insert drills form Ver 9 Converted to Ver X, the backplot looks good in Ver x, but not in verify. Will not do anything at all.

I use Pocket Rough,Rest mill for the small corners,Parallel finish, Parallel steep,(leaving stock)then Constant scallop(85% of the time) for the uniform Finish. Finish it off with pencil trace. And if it looks bad in a couple of areas scrub it with Flowline and use check surfaces. The trick of creating a 2-d path and projecting onto the surface works great as long as the walls are not to steep.

So Pete, if there are fillets on the corners, and I extrude the rectangle with these fillets, would it make a difference there? Does the system tolerance take over. Is this something one should even worry about? I could see it on a 3-d path. Thanks for you reply

Here is my question to the Forum,if I construct a 2-d rectangle, extrude a solid from it,attempt to contour a milling cutter around the outside profile, which is more accurate to chain, the Solid edge or the 2-d wire frame from which the solid came from? Is there an advantage to using the solid edge in this case?

I was playing with it today, seemed ok. I will look for the file

I switched everything over, Run my first class this Monday

Are you using "C" axis or "Y" axis in the Rotary setting(on the parameter page)or is it even have a check by it for it to take effect? Start there

Ver 9,Toolpaths,next menu, mill, next menu,wire frame?

If you are worried about the money then your intent is not in the right place.There is a difference between teaching and Demo's.Lot's of people know the software, but few know how to make the student successful.Lot's of patience will be needed.I am not saying your a bad Instructor, If you truly like what you do, then money follows automaticly. Where are you considering teaching at?
