Shipbuilding — Numerical control of machines — ESSI format
Serves as a guide in the co-ordination of system design, to minimize the variety of programs required, to promote uniformity of programming techniques, and to foster interchangeability of programs between NC drawings and flame cutting machines used in the shipbuilding industry. The "ESSI format" may be used in connection with any data code for punched cards, punched tapes, magnetic…
Numerical control of machines — Program format and definition of address words — Part 1: Data format...
Specifies requirements and gives recommendations for the data format for control systems used in the numerical control of machines. Improves the co-ordination of system design in order to minimize the variety of program manuscripts required. Is not intended for use in flame cutting machines and drafting machines used specifically and exclusively in the shipuilding industry.
Adopts ANSI standard X3.53-1976 and French standard NF Z 65-500 as PL/1 programming language standard for the English and French versions, respectively.
