BS 3641-2:1980

This standard BS 3641-2:1980 Symbols for machine tools is classified in these ICS categories:

• 25.040.20 Numerically controlled machines
• 01.080.20 Graphical symbols for use on specific equipment

This British Standard specifies basic designs for symbols intended for use on indicator plates of numerically controlled (N.C.) machine tools.

Drawings in this standard indicate the form of symbols only, and not their absolute dimensions.

The standard gives recommendations for proportions to be used in the design of symbols, independent of actual dimensions, and provides for the grouping together of symbols selected according to individual requirements.

Examples of groupings of symbols are given in appendix A for guidance.

NOTE. An index to BS 3641 : Parts 1,2 and 3 is given in PD 6490.
