Slide rule for calculating manufacturing costs of multiples of parts

Artifact Number:

2022-016

Description

A 21 cm by 5 cm, cardboard Shop Cost Calculator for determining the costs for multiples of identical parts manufactured in a machine shop.  Available inputs are labour cost per hour, operations per minute and even additional costs such as overheads. 

The calculator was developed by General Electric (GE) and this 1953 version has  shop-labour costs varying between $0.50 and $4.00 per hour.  Inflation has certainly changed that!  The reverse of the calculator has GE prices per unit length of various diameter rods of various metal or price per square inch of sheets of varying thickness. The name on the front is that of Alex Harvey, an engineer at Chalk River in the Accelerator Physics Branch during the design of the Intense Neutron Generator in the 1960s.
