APPENDIX METHODOLOGY FOR CAPACITY UTILIZATION Capacity Utilization Methodology .. producers of gears and gear products were asked to report the practical capacity and actual capacitylor their firms in 1 (table 1-, as measured in machine hours for the opera- tions specified below. Definitions of terms Machine hours. Machine hours are defined as machine time used on workpiece (.., run time) plus machine set-up time. Theoretical capacity. Theoretical capacity assumes running machine 2 hours day, 5 days week, or 1 hours. Respondents were asked to use percentage of theoretical capacity (such as 7 percent) that best characterizes their establishment' operations to calculate practi- cal capacity. Practical capacity. Practical capacity is the maximum level of machine utilization that an es- tablishment could reasonably expect to attain using realistic employee work schedule and the machinery and equipment in place. Practical capacity is run time plus set-up time. Practi- cal capacity, for example, can be assumed to be 7 percent of theoretical capacity (1 hours per week times 7 percent equals 8 hours per week of practical capacity) because of the time re- quired for machine maintenance, movement of materials, and other allowances. This factor (7 percent) may vary for manufacturing operations depending upon machine age, machine capability (numerically controlled or computer numerically controlled, etc.), work flow, the repetitive nature of manufacturing part or family of parts, etc. Actual capacity. Actual capacity is the number of machine hours (run time and set-up time) that machines are used. Hard finishing. Hard finishing is finish grinding or hard skiving of the gear teeth after the heat treatment operation. Table 1-1 Capacity utilization: Practical
