摘要： An intelligent machining system employs a neural network for calculating machining conditions on the basis of attribute data or a workpiece and a grinding machine. The system comprises a reference machining condition calculating unit, a neural network which receives the attribute data and provides corrections, and a correcting unit for correcting the reference machining conditions by using the corrections. Corrections which cannot be determined by means of empirical expressions or theoretical expressions are determined appropriately by the neural network previously learned. The system determines corrections for the machining conditions on the basis of machining errors decided by a neural network. The system also detects time-series machining phenomena by sensors, processes the output detection signals of the sensors by a neural network to obtain machining circumstance data. The feed rate of the tool is controlled by a fuzzy inference on the basis of the machining circumstance data.

摘要： Disclosed is a processing apparatus capable of optimizing its rule base comprising a plurality of rules having an antecedent and a consequent each. The antecedent contains input conditions of machining, and the consequent describes the result of machining. The antecedents are applied to input condition data. The consequents of the applied rules yield machining result data that are evaluated for rule fitness. When the rule base is updated, some rules are deleted and some preserved depending on their degrees of fitness. Between given two rules having the same consequent, any number of corresponding conditional elements in their antecedents are exchanged so as to generate new rules. The process is repeated until the rule base is optimized. With the antecedents of rules applied to input condition data and with the consequents of the applied rules yielding machining result data, those data may be modified according to modification request data. The consequents of rules are applied to the modified machining data, and the antecedents of these applied rules furnish corrective input condition data. This backward application of rules is an easy way to obtain corrective input condition data.

摘要： An apparatus capable of automatically determining grinding wheel dressing timing for dressing a grinding wheel. The apparatus estimates the abrasion of the grinding wheel in a grinding cycle on the basis of machining data and grinding conditions, and divides the grinding cycle into a plurality of stages according to the estimated abrasion to carry out grinding wheel dressing after the completion of every stage of the grinding cycle. In grinding a workpiece having a plurality of ground sections, the abrasion of the grinding wheel in grinding each ground section is estimated, and the abrasion is accumulated in accordance with grinding sequence. A ground section after grinding which grinding wheel dressing is to be carried out is determined on the basis of the cumulative abrasion. Similarly, the abrasions are accumulated for each of workpieces. A grinding wheel dressing is carried out after the completion of grinding a workpiece so that the cumulative abrasion may not exceed a predetermined value.

摘要： An apparatus for carrying out learning operation of a neural network which has an input layer, an intermediate layer and an output layer. Plural nodes of the input layer are related to plural nodes of the intermediate layer with plural connection weights, while the plural nodes of the intermediate layer are also related to plural nodes of the output layer with plural connection weights. Although input data composed of plural components and teaching data composed of plural components are used in learning operation, some of the components are ineffective for the purpose of learning operation. During error calculation between output data from the neural network and the teaching data, the apparatus judges whether each of the components of the teaching data is effective or ineffective, and output errors corresponding to the ineffective components are regarded as zero. The connection weights are thereafter corrected based upon the calculated errors. The apparatus further comprises means for adding new input data and teaching data into a data base, and means for calculating a degree of heterogeneousness of the new teaching data. The new input data and teaching data are added to the data base only when the degree of heterogeneousness is smaller than a predetermined value.

摘要： Disclosed is a brake band which includes a band and a lining connected to an inner peripheral surface of the band. The lining includes a plurality of grooves in its inner peripheral surface, the grooves which extend from an end to another end of the lining in an axial direction of a drum, rotating either in a clockwise direction or in a counter clockwise direction, obliquely with respect to an axial direction and a circumferential direction of the lining. The grooves include a communication passage which communicates an inner peripheral surface of the lining with the outside and which is disposed at a leading end of the grooves with respect to the clockwise rotational direction of the drum, and a trailing end of the grooves with respect to the clockwise rotational direction of the drum is disposed an inside of the another end of the lining. The brake band has a high cooling efficiency when the drum rotates in the clockwise direction. When the drum rotates in the counterclockwise direction, the oil is flowed to the trailing ends of the grooves, and it is blocked by the trailing ends. Accordingly, the oil is thus held in the grooves, and it is leaked gradually between the drum and the lining in a sufficient amount. Therefore, the brake band maintains the high cooling efficiency, and it inhibits the judder from occurring even when the drum rotates in the counterclockwise direction.
摘要翻译：公开了一种制动带，其包括连接到带的内周表面的带和衬里。衬里包括在其内周表面中的多个凹槽，所述凹槽沿着滚筒的轴向方向从衬套的端部延伸到另一端，所述凹槽沿顺时针方向或逆时针方向倾斜地相对于到衬里的轴向方向和圆周方向。凹槽包括连通通道，该连通通道将衬里的内周表面与外部连通，并且相对于滚筒的顺时针旋转方向设置在凹槽的前端，并且凹槽的后端相对于滚筒的顺时针旋转方向设置在衬里另一端的内侧。当鼓沿顺时针方向旋转时，制动带具有高冷却效率。当鼓沿逆时针方向旋转时，油流到槽的后端，并且其被尾端阻挡。因此，油因此被保持在槽中，并且在滚筒和衬里之间以足够的量逐渐泄漏。因此，制动带保持高的冷却效率，并且即使当鼓沿逆时针方向旋转时也抑制抖动。
