CNC machinesTotal completion timeHeuristic searchIn this study we attempt to deal with process planning, scheduling and preventive maintenance (PM) decisions, simultaneously. The objective is to minimize the total completion time of a set of jobs on a CNC machine. During the process planning, we ...
everyone has input and ultimately understands and accepts the role of preventive maintenance. Then, you can number crunch to determine what the cost of a machine breakdown will be versus a scheduled PM. Productivity can help you determine plans for each of your machines so you can determine...
On the basis of failure data gathered from 5 NC machine tools of one type in one year,a two-parameter Weibull distribution model is established,and this model has passed linear correlation test and hypothesis testing.On the principle of the most effectiveness,the best preventive maintenance interva...

Use and Application of Components for Preventive Maintenance of CNC Machine ToolsJiří Kuběnka
a method is proposed to solve the preventive maintenance in guards and CNC machines, preferably in those producing pieces of aluminium and/or alloys thereof, using liquid chemical products, where pieces are not dismounted and therefore the time and costs of maintenance are reduced as well as the...
CNC machinesmachining conditions selectiongeometric programmingIn this study we propose an operating conditions-based preventive maintenance (PM) approach for computer numerical control (CNC) turning machines. A CNC machine wears according to how much it is used and the conditions under which it is ...

CNC machineIn order to realize the intelligent maintenance management system, this paper presents a development of computerized preventive maintenance management system (CPMMS) to manage and record the maintenance information in the database for the CNC machines. The failure mode and effect analysis (...
