Introduction to the Machine shop



Accurate records are valuable. Unit officers are responsible for completion of forms, records, and reports. DA Pam 738750 lists records, reports, and authorized forms that are normally used for inspection and repair. Properly executed forms authorize and record repair or replacement of material.

The forms, records, and reports document the work required, follow the progress of the work within the shops, and indicate the status of the material upon completion of repairs.


The reports necessary to comply with the requirements of the Army Safety Program are prescribed in detail in AR 38540. These reports are required for any accidents involving injury or damage. For a listing of all forms, refer to DA Pam25-30.

Any deficiencies detected in the equipment covered herein should be immediately reported in accordance with DA Pam738-750. These reports will be submitted as an Equipment Improvement Recommendation on SF 368.


Machine tools are power-driven equipment designed to drill, bore, grind, or cut metal and other materials.


A complete list of machine tools including specialized machine tools currently authorized for issue is in Component List C 3405/70-lL.


In view of the different design and operating features incorporated in specialized machine tools (cylinder boring TM 9-9000-series technical manuals covering the specific machines.


To assure a high degree of safety, no machine -tool is to be used unless the risk management process as outlined below is understood and applied by the user and the supervisor:

1. Identify the potential hazard(s) that the machine tool can generate.

2. Assess the probability and severity of the hazard(s) by utilizing the Risk Assessment Matrix in figure 1-1. Risk acceptance decision authority for the risk levels is as follows:

a. Extremely high - CG, TRADOC; DCG, TRADOC; or the Chief of Staff,TRADOC.

b. High - Major subordinate commands, installation commanding generals, and school commandants of general officer rank.

c. Moderate and low - Delegated to the appropriate level in your unit chain of command.

3. Determine the risk control measures that will eliminate the hazard(s)orreduce the risk.

4. Implement the risk control measures before and during operation of the machine tool to eliminate the hazards or reduce their risks.

5. Supervise and evaluate the process. Enforce the established standards and risk control measures. Evaluate the effectiveness of the control measures and adjust or update them as necessary.


A. FREQUENT - Individual soldier/item - Occurs often in the career/equipment service life. All soldiers or item inventory exposed - Continuously experienced during operation/mission.

B. LIKELY - Individual soldier/item - Occurs several times in career/equipment service life. - All soldiers or item inventory exposed. - Occurs frequently during operator/mission.

C. OCCASIONAL - Individual soldier/item. - Occurs sometimes in career/equipment service life. All soldiers or item inventory exposed. Occurs sporadically, or several times in inventory service or operations/mission.

D. REMOTE - Individual soldier/item - Possible to occur in career/equipment service life. All soldiers or item inventory exposed, Remote chance of occurrence Expected to occur sometime in inventory service life or operation/mission.

E. UNLIKELY - Individual soldier/item - Can assume will not occur in career/equipment/service life. All soldiers or item inventory exposed. - Possible, but improbable.


I. CATASTROPHIC - Death or permanent total disability. System loss. Major property damage.

II CRITICAL - Permanent partial disability. Temporary total disability in excess of 3 months. Major system damage.

Significant property damage.

III. MARGINAL - Minor injury. Lost workday accident with compensable injury/illness. Mirror system damage.

Minor property damage.

IV. NEGLIGIBLE - First aid or minor supportive medical treatment. Minor system impairment.


EXTREMELY HIGH -Loss of ability to accomplish mission.

HIGH - Significantly degrades mission capabilities in terms of required mission standards.

MODERATE-Degrades mission capabilities in terms of required missions standards.

LOW - Little or no impact on accomplishment of mission.
