BS ISO 10791-1:2015

Defines with reference to ISO 230-1, the geometric tests for machining centres (or other numerically controlled machines, where applicable) with horizontal spindle (i.e. horizontal Z-axis).

This part of ISO10791 specifies, with reference to ISO230-1, the geometric tests for machining centres (or other numerically controlled machines, where applicable) with horizontal spindle (i.e. horizontal Z-axis).

This part of ISO10791 applies to machining centres having three numerically controlled linear axes (X-axis up to 5000mm length, Y-axis up to 3200mm length, and Z-axis up to 2000mm length), but refers also to supplementary movements, such as those of rotary, tilting, and swivelling tables. Movements other than those mentioned are considered as special features and the relevant tests are not included in this part of ISO10791.

This part of ISO10791 takes into consideration in AnnexesA through D four possible types of tables, fixed and rotary, as hereunder described:

• AnnexA: horizontal non-rotating tables;

• AnnexB: tables rotating around a vertical B’-axis;

• AnnexC: tables rotating around a vertical B’-axis and tilting around a horizontal A’-axis;

• AnnexD: tables rotating around a horizontal A’-axis and swivelling around a vertical B’-axis.

This part of ISO10791 does not consider accessory spindle heads, which are covered by ISO17543-1:—¹.

This part of ISO10791 deals only with the verification of geometric accuracy of the machine and does not apply to the testing of the machine operation, which should generally be checked separately. Tests not concerning the pure geometric accuracy of the machine are dealt with in other parts of ISO10791, as listed in the Foreword.
