TM 38-260

(2) The test patterns outline in detail the step-by-step procedures and methods to be followed in performing the

analytical inspection test.

(3) It should be noted that the analytical test patterns do not duplicate all tests conducted by manufacturers of new

machine tools. The primary purpose of the analytical test is the establishment of the tolerances to which the machine will

operate and hold. The tests indicated on the test patterns are considered to be sufficient and adequate to make such a

determination.

However, under certain circumstances, additional tests may be required. When this is done, a

description of the test and results shall be recorded in the space available on the test pattern form.

(4) The test, measurements, and tolerances for those machines which differ from designs given in the analytical

inspection forms are to be transferred to test records of similar types or an additional sketch made. For example, the test

pattern to be used on a four-spindle drill would be the test pattern for a single spindle drill of comparable design. The

alignment and run-out of each spindle will be identified and recorded by the number of spindles from left to right.

b. TMSs. TMSs are used in part to determine the operability/serviceability of IPE and the repair necessary to

return it to a specified level of performance.

(1) Any maintenance required on machine tools, as a result of analytical inspection shall be performed in

accordance with the applicable TMS.

(2) TMSs and analytical test patterns are used in conjunction with each other. For example, when an analytical

test pattern is required from DGSC, it will be attached to the appropriate TMS and forwarded to the requestor.

(3) DGSC develops all TMSs to cover all items of IPE in the DGSC inventory which may require maintenance.

The TMS may also be used to determine the serviceability of machine tools.

(4) TMSs arc available from DGSC, ATTN: DGSC-SSM, 8000 Jefferson Davis Highway Richmond, VA, 23297-

5501, for any of the machine tools that are DGSC controlled.

7-4. Personnel Qualifications

a. In performing tests and inspections on any machine tool, the importance of obtaining correct figures and data

cannot be overemphasized. Nothing less than accurate results will be acceptable.

b. Only personnel trained and experienced in performing precision work can be relied upon o obtain accurate

results. The degree of skill and experience required to perform tests and inspections is not acquired by any one

individual in any short period of time or course of instruction. It is experience gained over a considerable length of time in

the operation, maintenance, testing, and inspection of machine tools. Reliable data can only be obtained by conducting

tests using skilled and experienced personnel.
