Cutting machine and method

A cutting tool for removing material from an engine block structure, comprising:

• an engine block structure support sized to receive the engine block structure;
• a platform having a longitudinal dimension and a width dimension;
• a cutting assembly supported on the platform and movable in a longitudinal direction along an adjustable rail, and movable in a direction approximately orthogonal to the longitudinal direction, the cutting assembly including a rotary cutter;
• an alignment mechanism including an engagement structure configured to secure the cutting assembly to one of a plurality of predetermined positions on the adjustable rail;
• an adjustment mechanism for moving the adjustable rail and cutting assembly in the longitudinal direction to position the rotary cutter to a desired position;
• and
• a camera and display system showing a position of the engine block structure with respect to the rotary cutter.

A cutting tool for removing material from a crankshaft saddle of a crankcase portion of an engine block, comprising:

• a support sized to receive the crankcase portion;
• a platform having a longitudinal dimension and a width dimension;
• a cutting assembly supported on the platform and movable in a longitudinal direction along an adjustable rail, and movable in a direction approximately orthogonal to the longitudinal direction, the cutting assembly including a rotary cutter;
• an alignment mechanism including an alignment pin configured to secure the cutting assembly to one of a plurality of predetermined positions on the adjustable rail, the plurality of predetermined positions corresponding to positions of a plurality of crankshaft saddles of the crankcase portion;
• an adjustment mechanism for moving the adjustable rail and cutting assembly in the longitudinal direction to position the rotary cutter to align the rotary cutter with bearing grooves of one of the crankshaft saddles;
• and
• a camera and display system showing a position of the bearing groove with respect to the rotary cutter.
