Multi Slot TMI Measure based Machine Scheduling for CNC Applications with Improved Data Security

P. Velmurugan, A. Kannagi and P. John Paul

The modern manufacturing process has been adapted with computer numerical control machines. Number of protocols has been discussed earlier for the improvement of production yield with secure access. However, the performance of scheduling and data security in CNC applications is still challenging due to the security issues. To overcome the deficiency, an multi slot TMI (Throughput-Makespan-Idle Time) based scheduling algorithm is presented. The proposed work performs scheduling of CNC machines and their operations to improve the scheduling performance. The presence of multi slot in CNC machines enables the processing of more than one operation in the batch process. By identifying a sequence which is efficient in terms of throughput, makespan and idle time makes the CNC machine to produce higher outcome. The data security has been enabled with attribute based encoding to improve the security of data in CNC applications. The method produces efficient results on scheduling as well as data security.
