* 机电技术专业英语 Lesson Twenty-one Text Several specific benefits can be expected from the adoption of computeaided process planning techniques: (1) Reduced clerical effort in preparation of instructions. (2) Fewer calculation errors due to human error. (3) Fewer oversights in logic or instructions because of the prompting capability available with interactive computer programs. (4) Immediately access to uptodate information from a central database. (5) Consistent information, because every planner accesses the same database. (6) Faster response to changes requested by engineers of other operating departments. (7) Automatic use of the latest revision of a part drawing. ComputerAided Process Planning1 Lesson Twenty-one (8) Moredetailed, moreuniform processplan statements are produced by wordprocessing techniques. (9) Moreeffective use of inventories of tools, gages, and fixtures and a concomitant reduction in the variety of those items. (10) Better communication for production planning, including cutter life, forecasting, materials requirements planning, scheduling, and inventory control. (11) Better information for production planning, including cutter life, forecasting, materials requirements planning, scheduling, and inventory control.
