Abstract
A testing and inspection recording apparatus for use in recording the operating conditions and physical condition of a metal working tool such as a motor driven band saw or the like has a portable computing unit programmed to receive, store and reproduce information regarding the type of machine being tested, the physical condition of the machine, the particulars of the owner's name and location of the machine. The computer is programmed to calculate the cross-sectional area of a particular workpiece after inputting of data regarding one or more linear dimensions of the workpiece. Proximity switches are connected to the computing unit. The switches are mounted to measure the initiation and the completion of a cutting operation and the completion of an operating cycle of the machine. The computing unit is programmed to produce a field test analysis report giving full particulars of the machine, the material being cut, the operating tool or saw blade specification, the actual cutting time per cutting cycle and the cutting rate in area per unit time per cutting cycle. The computing unit is also programmed to produce a machine inspection report based on input data observed by the machi…
