Abstract: A track system includes an attachment assembly including at least one of a first pivot defining a roll pivot axis, a second pivot defining a pitch pivot axis, and a third pivot defining a yaw pivot axis of the track system. A frame assembly is disposed laterally outwardly from the attachment assembly and connected to the attachment assembly. The track system further includes at least one actuator for pivoting the frame assembly about at least one of the roll and yaw pivot axes, and at least one monitoring for determining, at least indirectly, at least one of a state of the track system and a ground surface condition. The at least one monitoring sensor is communicating with a track system controller to control the operation of the at least one actuator based on the at least one of the state of the track system and the ground surface condition.

Abstract: A method for machining a molding core from an aggregate material block, comprising: positioning the aggregate material block on a rotative base member; and rotating the base member and simultaneously machining the aggregate material block into the molding core. There is also provided a method for forming a casting mold including a molding core and a foundry casting core comprising: a core body having at least one convex shaped core print. The method comprises: providing at least one molding element having a mold cavity with at least one core-print pocket defined in a top side of the molding element; forming the molding core having at least one convex shaped core print; and inserting the molding core in the mold cavity with the at least one convex shaped core print engaged in a respective one of the at least one core-print pocket.

Abstract: A method for machining a sand molding element, comprising: inserting at least one hollow center body having an internal cavity in a predetermined position in a casting flask; filling the internal cavity of the hollow center body with unbonded sand; filling the casting flask with bonded sand to obtain a sand block; machining a mold cavity in the sand block; and emptying the internal cavity from the unbounded sand. There is also provided a method for machining a molding core from a sand block, comprising: providing a core base member having a concave upper surface; forming a sand block on the core base member with a lower surface of the sand block resting on the concave upper surface; and machining the molding core into the sand block, the molding core having a convex lower surface complementary to the concave upper surface of the core base member.
