CUTTING A PIECE

[manel]

HI

i want to cut a piece from a stock and then machine it to the exact dimension.

which is the best toolpath to do it ?

which toolpath  allows  to ramp or helix around the piece without plunging directly into the material

i used to use countour ramp but i think it is not efficient, it plunges vertically  to the material

You would probably be best to share your Mastercam file

I'm having a hard time understanding your question, but contour ramp is capable of ramping around the profile without plunging straight in to the material.

If you post a Mastercam file somebody will help you out.

Contour Ramp has 3 options

Plunge does just that, plunges vertically at the end of each pass

Depth ramps around the part at the depth you specify... this is the option you probably want

Angle  ramps around the part at the specified angle..

He just wants to rough and finish a part, from a solid block of material.

You want a path like Dynamic Opti-Rough.

Yes show us your work so we can help. Was this a MCAMFSW file with toolpaths in it?

Your path looks fine.  Give it some lead in/out or make your top of stock higher.

sorry , but i have posted may mastercam for solidworks file

mY question is what is the best tool path to cut a piece from a large stock in order to machine it with the right dimension later .

i used countour ramp but the tool is always engaged and steel down , i can't do retract after each depth

 

[jlw™]

use the same contour but depth passes instead of ramp.

I would suggest Dynamic Motion Technology. There are many videos and materials online that will go over using the toolpath but from a chaining standpoint I listed everything that you need to know to get the toolpath started in the picture below, If you setup the chaining as shown then all you will need is just the toolpath parameters and cutting conditions.

On a side note, Your question originally was what is the "Best" way to cut the part, in my opinion this is a difficult question with the very little info you provided because what may be the Best for me may not be the Best for you since things like Runtime, Accuracy, Quantity of parts to produce, Tooling, machine capabilities, etc. all play a driving factor in machining strategies and toolpath selections.

On the odd chance that you actually purchased Mastercam, how about you take advantage of the free classes you get?
