M.; Morade, S. S. Abstract: - Computer numerical control (CNC) is a method for automating control of machine tools through the use of software embedded in a microcomputer or processor attached to the tool. It is commonly used in manufacturing for machining metal and plastic parts. Previously CNC machine is attached with computer and all the commands are given using computer. Now a days DSP processor is used in modern CNC systems having USB and SD card slots through which we can program CNC machine. The problem with the existing computer based system is it needs to connect to the CNC system as communication take place through the RS232 protocol. The use of RS232 is very inefficient and time consuming than the latest CNC systems due to its slow speed. Replacement of RS232 by USB or SD card communication has increased the speed from 115.2 Kbps to 12 Mbps. In this study DSP processor by Texas Instruments TMS320F2837xd is used which is dual core processor with features of flash programming. This study focuses on understanding and analysing file conversion program to optimize the feed rates and reducing overall machining time of CNC machine. The input to the file conversion program is tool path file generated from CAM software and output is the file with suitable feed rates and other parameters required by CNC machine. 2019-07-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/2834 Title: SD Card Based File System for CNC Machine using TMS320F2837xD Processor Authors: Dhikale, D. D.; Morade, S. S. Abstract: - The main objective of this paper is to implement SD card based file handling system for CNC machine.CNC machine uses numerical data to control a machine. The system uses dual core DSP processor with c28xx core. Implementation of file system for CNC machine reduces the file processing and tool processing time to a great extent. The dual core DSP processor is interface with the SD card for large storage of data in CNC machine. The TMS320F2837xD control card has SD card slot so file system can be designed for CNC system. The algorithm for file handling for CNC machine is implemented using Texas instrument Code Composer Studio IDE environment. The another important task of this experiment is to convert the .CNC file into the machine acceptable format for the tool processing and file processing in the CNC machine. 2019-07-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/2832 Title: Heart Rate Monitor using IOT Authors: Jadhav, S. R.; Bhabad, S. S. Abstract: — These days we have increased the percentage of heart diseases including increased risk of heart failures. Our system uses sensors that allows to detect heart rate of patient using heartbeat sensor even if the person is at home. The sensor is then interfaced with our selected microcontroller that checking time to time heart rate readings and transmitting them over internet. The user can set the heart beat limits high and low. After sensing these limits, system will monitoring and if the patients heart beat is goes above the limit, system will send the alert message to the controller which then transmit this data over internet. System always monitors for high as well as low blood pressure. Therefore one who monitor heart rate as well as get an alert message of heart attack to the patients directly from all around the world. 2019-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/2323 Title: Study Of RFID Authentication Protocols Authors: .Jadhao, Ms. A.G; .P.Ugale, Prof. Dr. S Abstract: For identification of objects and humans, recently we are using a small wireless device which named as RFID. Acceptance of this system is growing day by day in previous few decades and growing with new protocols. It has reduced cost of production and this is the reason that RFID technology and devices are used in the huge mob. As security is the main issue of the communication while doing data transmission in RFID devices. Though RFID is complete wireless network system, security of data is more important. There are many authentication protocols are used for data security from tag to reader communication. Here we have done study of various authentication protocols and what is the requirement of it. Few protocols are providing forward security, performance but lagging in privacy purpose likewise other protocols are doing the same. 2018-07-01T00:00:00Z
