Solved: Pathing a Ball Mill/End Mill combination

Solved: Pathing A Ball Mill/End Mill Combination

hey there, i'm trying to machine a finger hold in some mdf and i've got a 3/8 ball end mill to preform the task. ideally i'd like to machine a flat area and then have the ball produce the radii corners; in whatever order would be preferable. i've tried a number of different tool pathing set ups,...

Optimization of processing parameters of a ball mill

Optimization Of Processing Parameters Of A Ball Mill

the aim of this work was to optimize the ball mill based refining process of chocolate, in terms of refining time and energy consumption. experiments were planned following a central composite design (ccd), considering refining time (rt) and agitator shaft speed (as) as factors.the experimental variables measured were chosen from the main characteristics that describe unmoulded chocolate.
