After a connecting rod for an engine is formed, it is broken or fractured at a fracture point to allow the connecting rod to assemble around a portion of a crankshaft. However, before fracturing the connecting rod, the connecting rod is provided with a layer of paint across the eventual fracture point such that when the connecting rod is fractured the paint extends across both sides of the fracture point. Also before fracturing the connecting rod, serial numbers or symbols are etched into the paint on either side of the eventual fracture point. These serial numbers are unique to that connecting rod, and have similar indicia on either side of the connecting rod. The combination of the paint and serial numbers increase the ability of an assembly worker to assure matching parts of an original connecting rod are re-attached during assembly about the crankshaft.

An apparatus for processing the surface of a workpiece includes: a first rotating body connected to a first rotating shaft and including a first protruding portion connected to a part of the outer circumference thereof; a second rotating body connected to a second rotating shaft and including a second protruding portion connected to a part of the outer circumference thereof; and a third rotating body connected to a third rotating shaft and including a third protruding portion connected to a part of the outer circumference thereof, wherein the first to third rotating shafts are in the same plane, a first angle between the first and second rotating shafts, a second angle between the first and third rotating shafts, and a third angle between the second and third rotating shafts are identical, outer circumferences of the first to third rotating shafts adjacent to one another form a pathway through which a workpiece can pass, and the size of the pathway is adjusted by moving the first rotating body.

A spindle mountable camera system connectable to a CNC machine for work piece inspection and identification. The camera system includes a mounting stem connectable to a CNC machine tool holder. The mounting stem includes an air passage connectable to an air supply of the CNC machine. An enclosure is attached to the mounting stem and includes a camera opening. A camera module is disposed within the enclosure and an air supply line is connected between the mounting stem and the camera module. An enclosure cover is pivotably mounted to the enclosure proximate the camera opening. One or more pneumatic cylinders are connected to the air passages and extend between the enclosure and the enclosure cover to move the enclosure cover between an open position and a closed position.

A steel strip with a plurality of markers and a method for marking a steel strip with material properties is provided. The method comprises measuring material properties of the steel strip at a plurality of discrete strip positions. A plurality of markers are applied to the strip edge at the strip positions, each marker from the plurality of markers containing a material identifier relating to the measured material properties at the respective strip position of the marker.
