Svenakela, those last two posts clarify things a lot. In fact I think I had the wrong idea until now. What you have just explained is that Stock to Leave will in many, most (or all?) cases be used as an offset (similar to OffsetSrf).
This was the statement that made me understand: "Lets say you have a sphere that has a diameter of 50 mm. If you set Stock To Leave to 1 mm, the toolpath will leave a sphere that is 52 mm. The tool will stay away from the object with 1 mm in every direction. Then you can create a new toolpath with Stock To Leave set to zero and that will make you a sphere with exactly 50 mm in diameter. With this strategy the last toolpath will only run in 1 mm of material and will make a very smooth surface."
Normally I am quick to learn, so I wonder what got in my way. Anyhow, for the tutorials the above might be a key statement around which you can build further explanation. I think the word 'offset' helps too. |
