The IBM 602 Calculating Punch, introduced in 1946, was an electromechanical calculator capable of addition, subtraction, multiplication, and division. The 602 was IBM's first machine that did division. (The IBM 601, introduced in 1931, only multiplied.) Like other IBM calculators, it was programmed using a control panel.

Parsons was able to calculate helicopter airfoil coordinates with an IBM 602A multiplier. He then fed the data into a punched card, which he used on a swiss jig borer. This information led to the manufacture of many helicopter blades and aircraft skins. According to the accepted CNC history, this was considered the first CNC machine.

She was one of the experts in the Southeast on the 602A Calculating Punch.\nSometime her job required travel to other cities in the Southeast\nto help IBM's customers. \n The 602A could read in a punched card, read numbers and other signals\noff of it, do some arithmetic calculations, and punch the results\nonto the same or a different card ...

This white paper punch card demonstrates how an average hourly rate of pay can be calculated for a worker paid partly on piece work and partly on day work, receiving a bonus. It was intended as advertising for the IBM 602A calculating punch. …

The results of these calculations can then be punched into the same cards from which the factors were read or into ...

The IBM 602 Calculating Punch, introduced in 1946, was an electromechanical calculator capable of addition, subtraction, multiplication, and division. It was programmed using a plugboard control panel and was IBM's first machine that did division. The 602 was available in four models: Model 1, Model 2, Model 50, and Model 51.
