摘要:
Machining procedure extracting means extract machining procedures (information about tools, cutting conditions, and the like) based on a machining command of an NC program, and machining procedure outputting means display the machining procedures on a CRT display unit or the like. Thus, a machining operator can easily prepare for machining.

An automatic production system includes an automatic washing device usable to wash off swarf left on a workpiece by an NC machine tool. The automatic washing device is used before measuring a portion of a workpiece using a three dimensional measuring device controlled by a measuring part program controlling the three dimensional measuring device. When automating an operation of the washing device, a washing program is produced based on the a measuring part program controlling the three dimensional measuring device to be able to efficiently wash a minimal area of the work piece encompassing the portion of the workpiece to be measured.

There is provided a method and device which extracts as a running operation history a modification made to an NC program for numerical control of machine tools which has already been completed. After making an NC program, modifications are made to the NC program prior to the actual operation so that experience in field work or results of test machining can be reflected. An optimum NC program can be obtained through such modifications, and contents of the modifications are extracted from the NC program as a running operation history to produce a data base. The running operation history data base is reflected in subsequent preparation of NC programs having similar conditions.
摘要:
A tool management method, when performing machining using a Numerical Control (NC) program, searches for cutting tool status information obtained as a result of having performed a machining simulation based on tool information, cutting condition information and the NC program, and on the other hand, actually measures tool wear at the time of actual cutting, estimates the tool wear from each of the items of information described above and judges permission to use a tool.
摘要:
An apparatus and method for generating numerical control information for numerically controlling machine tools. Contents of corrective editing or correction to numerical control information by a processing operator is written and stored in a processing method database as processing knowledge of the processing engineer. When a programmer generates new numerical control information, a suitable processing method can be used from the processing method database. The knowledge included processing conditions by the processing operator. The information in the processing method database is updated at each and every processing.
摘要:
In NC machining in which machining control is performed through An NC program, machining conditions at the time of actual machining are reflected in the NC program. At this time, there are two types of modes comprising an analytic storage mode in which actual machining conditions are reflected in the NC program as they are and an optimization mode in which optimization processing applies to the actual machining conditions and the result is reflected in the NC machining program, and either of them is selected according to conditions.
摘要:
A method and apparatus for NC machining management based on a measurement program, wherein a machining shape at an arbitrary machining stage is determined by an NC program, a geometric element or a geometric model is generated, and a measurement program is generated on the basis of the geometric model. The measurement program is executed when at least one of the steps of the NC program is completed, and the results of measurement are used as control information for machining measurement.
摘要:
A method and device to automatically determine the operation balance of processing/assembly machines such as NC machine tools. The device detects the machine operations related to income and expenditure as income/expenditure data and stores the income and expenditure amounts in a memory based on the detected income/expenditure data and calculates the income/expenditure balance of the individual machines for an arbitrary period based on the stored income and expenditure amounts. In the NC machine tool, the operations related to the income and expenditure can be detected while monitoring the execution statuses of the NC program. By calculating the income/expenditure amounts with multiplication of such operations by the predetermined unit prices of income or expenditure and subtracting the expenditure amount from the income amount, the operation balance of the machine for each cycle or every week or month can be determined.
摘要:
A device for analyzing NC program is provided with a machining method analyzing means (34) which extracts machining conditions for every machining work element by analyzing an actual NC machining program, and data base creating means (35). The device extracts necessary machining information from the actual NC machining program and allows the data bases (21, 22, 23 and 24) to reflect the information.
摘要:
In the present invention, for an NC program for controlling a machine tool, information for machining quality required by a machine tool is prewritten in the program. A measurement program for measuring the machining quality of the workpiece using a measuring machine is produced by analyzing the NC program. The machining quality of the workpiece is measured by the measurement program and the measuring machine. The machining quality of the workpiece can be judged by comparing the measurement results and the machining quality information included in the NC program. By utilizing this quality judgement, simple and effective system control can be achieved when a system such as CIM (Computer Integrated Manufacturing) is constructed in cooperation with other machine tools.
