Abstract
The paper describes the preparation of machine control tapes using a computer programme package, and the B.S.R.A. (British Ship Research Association) part-programming processor system. The comprehensive nature of the system, the development of a modular basis and the modification of the general engineering 2CL to provide a shipbuilding version are described.
N.C. (Numerical Control) machines in use in shipbuilding include automatic draughting machines, several varieties of N.C. flame-cutting machines and their associated computer programmes, and a N.C. frame bending machine.
The advantages of Numerical Control are listed and the importance of considering the system as a whole is emphasized.
