Hi,
I'm a robot system integrator with lots of skills on milling application.
We propose and sell a off-line robot simulator and postprocessor called Eureka
http://www.redsrl.net/en/products/softwareproducts/eureka.html ...just have a look.
Anyway....consider that it's not enough to have a postprocessor and off-line simulator if you want to mill.
You should have also something that can handle large amounts of data that are typical of milling program. This is because robot memory is limited compared to movements number of a milling finishing program.
For example we use an application, developed by ourselves, that manages large amount of data from an external PC but it's available only for MOTOMAN and KUKA, not for FANUC yet.
Hope this helps,
Milena.
