Hi,
I have lots of problems and gripes every time I try to use 2-d milling. I avoid it whenever possible because of these problems.
Unfortunately, not every job can be cut with 3-d toolpaths.
When I am forced into using the 2-d paths, one thing that really bothers me is the lead-in / lead-out section.
I often find myself trying to contour around tiny details that require very small lead-ins to avoid gouging the part.
Whenever I do this I find myself wondering a couple things...
1. Why is TS Cam not smart enough to avoid gouging the part in 2-d milling ops ?
2. Why is the lead-in required to be so long ? It seems like the radius of the tool is the minimum allowed lead-in. What I really need is the ability to specify something like a .002 perpindicular lead-in on my contours.(just enough to turn on compensation)
Have I missed something or is TS Cam deficient in this function ?

Hi TopNoob.
I don't know if I really undresttod your doubt, but I have been working 90% of time with 2D milling operations.
I know that the minimum lenght of the lead in/out values must be the radius of the tool and I also suggest you select the option Corrected instead of shifted or original in the combobox for compensation method. It really works fine for me... I have an application where I work with a 6mm diameter millint toll in 6.35mm path... I work with Lead in/out values of 3.1mm for this opperation (perpendicular type) and it works fine on machining.
In your case, if you are working with a milling toll of .25in I suggest you to input lead in/out values like .254
I hope that this information help you to work with 2D milling.

Concerning "Lead in distance" or "Lead out distance" for example you can add in those field "Tool.rad/2" for example. Unfortunauteley, it doesn't seem to work with the "Lead in/out overlength

In Approach/retract area, you just have to tick the option "Lead out is the same as Lead in".and how can i say leadin ia the same as leadout

how can i set the option "Lead out is the same as Lead in" so that this is always on?
Hello,
If you want this option for all milling option,
Check the menu:
Edit -> Change default values -> Milling -> Global -> Lead in distance,
Be careful, two approach types have the same name, the second one is for tangential Lead in.
Once you've added your préferences, choose the option "Lead out as same as lead in" (Parameter name is "Retract_same_attack",
