Canned cycle

[cuda383]

Hi all

 

I'm new to mastercam lathe(V9) and having a hard time with this : Bondaries are all set and my shape is drawn.It's only a face with a diameter and there's a radius of .250" on the corner.Facing is ok, but when I rough my OD using canned cycle (toolpaths-canned rough),I select chain and pick my first line that is my radius and the last one and select done.

Set my roughing parameter and hit ok. I get that

message : "Tool collision with stock ! Continue writing toolpath ?"

 

What could be the problem ?

 

Still searching !

 

But if I do the same thing but without canned cycle (toolpaths-rough) it's ok !!

 

Hope you understand what I mean ! (I'm canadian french)

 

Thanks

When using canned cycles (whether programming manually or with CAM) you need to pick a retract point. This is the initial position where the canned cycle is activated and where the tool returns once the cycle is finished.

 

If using canned cycles for roughing in Mastercam, you should create a point at a clearance position, and pick it right after you have chained your geometry. Mastercam prompts you for it.

Hey Cuda! d'ou es-tu ? Tu nous donnes pas beaucoup d'infos à ton sujet.

i agree with peter.

i think the problem is at your starting point,

because of the stock has a sharp corner and you start the chain at at radius, you are gouging the part. i try what you did and did the same thing

ad a line at the lead in/out parameter.

hope this helps!

what rob said , thats the problem i work mainly with lathe work and when you use canned cycle face you have to start part past your stock chain for clearance
