Axis - The trisquare (TS) is standing on the machine table. Readings of the dial gauge (G) are taken when it is brought, by rotation to the spindle (S), into two positions shown (i.e. in firm and dotted lines). The difference between the readings gives the error in parallelism between the spindle axis (AA) and the table surface (T).
To check the parallelism between the spindle and table movement, the readings obtained in the are utilized.
