Lathe Face Grooving - Tool Containment

[Tim Simmermon]

I am having a problem creating a Face Grooving Tool Path in MCX3. I have done this many times before, but for some reason this one is giving me a headache. The face groove requires using a square insert. I chain the geo, go thru the parameters (it is set to face 0 Deg), and the toopath is not contained inside of the geometry. It also takes 17 passes (using a .062 wd insert for a .14 wd groove). If I change the tool to a full radius insert, then it stays contained, and only takes a few passes.

 

I loaded the file onto the FTP (T_SIMMERMON_FACE_GROOVE.mcx)

 

If anyone has any ideas or has run into this before, I sure could use your help.

 

Thanks!

I recreated the tool and it works fine. Must've been something wrong with the tool. Thanks if anybody started looking at this.

several problems -

chains for ops 4&5 are wrong side (tool inside part) reverse and/or change side...

enable "use stock for outer boundary" on groove parameters both ops 4&5

op4 t202 has no control points. redefine as .062 x .094 w/.005 conrad, regen,all set

op5 has roughing and finishing enabled. groove already roughed in op4. disable roughing, make finish only, all set.

Be careful with "use stock for outer boundary in facegrooving" Mike; "error making groove toolpath" may be your result. John Paris logged a bug that I found last week...

Thanks Chris...bigger part of the problem was loss or lack of control points on the tool and

rough params not disabled in op5....I'll take your advice and regen without that option checked.

Mike,

 

Op#5 was just to show that the full radius grooving tool was acting correctly vs. the square grooving tool. I was not using OP#5 in the actual program.
