摘要： A cam grinding machine rotates a workpiece by using a servomotor which is capable of being rotated at a variable speed. A memory device stores data of rotational speeds of the workpiece corresponding to angular positions thereof in order to maintain the circumferential speed of the workpiece constant. A detecting device detects an angular position of the workpiece. A counter is responsive to the detecting device and reads out rotational speed data stored in the memory device in order to apply the same to the servomotor.

摘要： A tool position offsetting system for a spare tool, including a tool life detecting device provided for detecting a broken or substantially worn tool and for replacing the same by a spare tool, and a detecting device which detects whether the spare tool is inserted in the tool spindle. If the detecting device makes a detection, an input controlling circuit applies several signals to a numerical controller so as to instruct the same to introduce the dimensional data for the spare tool into the memory of the numerical controller, resulting in amending the offset data stored in the memory before a machining operation. After the machining operation, the input controlling circuit applies several signals so as to remove the dimensional data from the memory, resulting in restoring the tool offset data to its original setting.

摘要： The function block memory unit stores a plurality of function blocks by programming each ladder circuit for computing output signals which has to be determined based on input signals from each safety device according to a connection specification of the safety device. The ladder circuit satisfies a predetermined safety standard, and thus, the function blocks satisfying the safety standard are used. The program link unit sequentially links each function block received from the function block memory unit based on the ID number of each I/O module to automatically create the safety program. The corresponding function block can be uniquely determined based on the ID number.

摘要： A numerical control system is provided wherein numerical controllers associated with machine tools are respectively coupled to auxiliary controllers communicating with a host computer. Each auxiliary controller has a memory for storing revision values which respectively correspond to primary and spare tools being stored in a tool magazine of the associated machine tool. When a spare tool is attached to a tool spindle of the associated machine tool in place of a primary tool, each auxiliary controller reads out a corresponding revision value from the memory and transfers it to the associated numerical controller. Thus, a corresponding one of tool dimension compensation values being stored in a memory of the associated numerical controller is revised or modified by the revision value transferred thereto so as to adapt itself for the spare tool being used on the tool spindle. Further, when the primary tool is taken out from the tool magazine and a secondary spare tool is set up therein instead, the host computer reads out from its memory a revision value corresponding to the secondary spare tool and transfers it to the auxiliary controller. This revision value is stored in the memory of the auxiliary controller for later transfer to the associated numerical controller in connection with the use of the secondary spare tool on the tool spindle.

摘要： In a numerical control system, a plurality of machine tools are provided each having a tool spindle, a tool magazine for storing primary tools along with spare tools respectively associated with some of the primary tools, and a tool changer for changing tools between the tool spindle and the tool magazine. A system control host computer included in the system divides the operational period of each machine tool into a plurality of operational period sections and calculates prospective used times of primary tools which are programmed to be used on the tool spindle in accordance with at least one numerical control program within each of the operational period sections. The host computer then estimates primary tools whose lives will expire within each operational period section, based upon cumulative past used times, the prospective used times and life times of the primary tools and searches for tool number data of spare tools associated with the estimated primary tools. The tool number data of the spare tools are applied to a tool replacing controller which controls tool replacing robots and a tool transporter provided between a tool stocker and the tool magazine of each machine tool, so that the spare tools can be transferred from the tool stocker to the tool magazine of each machine tool.
