The objectives of this research have been successfully attained after two years of research. The major research results obtained are as follows ;1. Architecture of CNC device embedded scheduling function and tool path generating functionA new type CNC device for machine tools is proposed and the architecture of the CNC devices is planned in order to aid decision-making by multi skilled workers. The proposed CNC device provides scheduling function and tool path generating function for the workers. The worker can know an influence for whole manufacturing system caused by his decision-making through the scheduling results. Furthermore the worker can change the cutting plan without CAM systems.2. Improvement of decentralized scheduling methodRecursive propagation method, which is an information exchanging protocol for the decentralized scheduling proposed by the applicant, is improved to aid the decision-making by the multi skilled-workers. The improvement is related to an estimation of candidate schedule based on scheduling theory. The formats of the scheduling problem, manufacturing environments, and resources model are proposed as one of the interfaces of the proposed system in order to interact the workers.3. Immediate offset methodA new tool path generation procedure is proposed in order to generate the tool path for machining of free form surfaces without aid of CAM systems. The proposed method is focused on calculations for offset position of a product required to control the tool position in machining. The workers can change the process plans supported by the proposed CNC devices.

经过两年的研究，本研究的目标已成功实现。取得的主要研究成果如下：1.嵌入调度功能和刀具轨迹生成功能的数控设备体系结构提出了一种新型的机床数控设备，并规划了数控设备的体系结构，以辅助多技能工人的决策。该数控装置为工人提供了调度功能和刀具轨迹生成功能。工人可以通过调度结果了解自己的决策对整个制造系统的影响。此外，工人可以改变切割计划没有CAM系统.分散调度方法的改进递归传播方法是申请人提出的一种用于分散调度的信息交换协议，它被改进以辅助多个熟练工人的决策。改进涉及到基于调度理论的候选调度估计。提出了调度问题、制造环境和资源模型的格式，作为该系统的接口之一，以便于工人之间的交互.直接偏置法为了在不借助CAM系统的情况下生成自由曲面加工的刀具轨迹，提出了一种新的刀具轨迹生成方法。所提出的方法是集中在计算偏移位置的产品所需的控制刀具位置加工。工人可以更改由建议的CNC设备支持的工艺计划。
