Computer Controlled Measuring Table

Computer algorithms exist to make a series of measurements satisfying predetermined conditions of accuracy and reliability with minimum effort. A measuring machine is described below to exercise and demonstrate these algorithms.

Therefore, a densitometer was used which can make measurements over small regions in a larger plate. It is very difficult to alter the range of the sweeps of this instrument. It was desired to replace the densitometer by a moving table, which could look at an area placed anywhere in a larger area and have all the control operations entirely governed by a computer. The computer in addition, dictates all the set up operations which in the densitometer were manual. For example in the previous operation, if it were set up to sweep or check a length 1 mm it was necessary to take the table apart and change the lever arms, a procedure which upsets all prior adjustments. In the new table described herein such a change can be made by merely typing a command at the input console, and all prior reference points are maintained. This new machine can be computer directed to make any integral number from 2 to 16000 of measurements over a range of 0 to 2 inches and this span can be placed anywhere in rectangle of approximately 2 x 6 inches. and all control comes via the computer console, so that in a very real sense the complex of computer table is interactively coupled with the operator via the typewriter and computer display.

Basically, the system operates by drivin...
