Topic for This Month:Parallel Kinematics

* Parallel kinematic device for connecting fixed platform to mobile platform uses three connecting elements engaging with common point of one of platforms to form a triple point with simple mechanical configuration.

* Press for material shaping, has head piece with plunger moved up and down with respect to table, where head piece is movable platform of parallel kinematic device, whose stationary platform is fixed in position with respect to table.

* Control method for processing five-rod five-ring parallel kinematic machine tool.

* Method for calibrating parallel kinematic mechanism, method for verifying calibration, and method for taking correction data.
