Preface
The purpose of this training circular is to provide a better understanding of power-driven machine tools. It also supplements technical manuals in the 9-3400-series covering power-driven machine tools. One of the main objectives is for this publication is to be clear and understandable. Illustrations throughout this publication show the step-by-stepprocess of many machine shop operations. The tables, charts, formulas, weights, and measurements in this publication can be a ready reference for selecting the proper tooling and math formulas for machining different materials. The proponent of this publication is HQ TRADOC. Send comments and recommendations on DA Form 2028 directly to the Department of the Army, Training Directorate, ATTN: ATCL-AO, 801Lee Avenue, Fort Lee, Virginia 23801-1713.

INTRODUCTION TO THE MACHINE SHOP GENERAL INFORMATION
FORMS, RECORDS, AND REPORTS 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 materiel. 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. FIELD REPORT OF ACCIDENTS The reports necessary to comply withthe 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 Pam 25-30. Any deficiencies detected in the equipment covered herein should be immediately reported in accordance with DA Pam 738-750. These reports will be submitted as an Equipment ImprovementRecommendation on SF 368. DEFINITION OF MACHINE TOOLS Machine tools are power-driven equipment designed to drill, bore, grind, or cut metal or other material. LISTING OF MACHINE TOOLS A complete list of machine tools including specialized machine tools currently authorized for issue is in Component List C 3405/70-lL. SPECIALIZED MACHINE TOOLS In view of the different design and operating featuresincorporated in specialized machine tools (cylinder boring machines, brake reliners, valve seat grinders. and so forth) by various manufacturers, no attempt has been made to include information pertinent to them in this manual. For complete information on these tools, see pertinent TM 9-3400-, TM 95100-, and TM 9-9000-series technical manuals covering the specific machines. RISK-MANAGEMENT To assure a highdegree 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 isas 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) or reduce 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/update them as necessary.
