So different design which uses rotary mechanism. Due to the rotary mechanism continuous operation and also increases in the speed of operation is ensured. This project also aiming to make operation automatic by using Arduino to control feeding mechanism. Mathematical modelling has been done for checking machine for different stresses and finding out optimum dimensions. Furthermore, machine components were tested on ANSYS software to find deformation in actual workloads. Key Words: Roller, DNS Test, Laser Cutting 1. INTRODUCTION The Automated card sheet cutting Machine system is a combination of electronic mechanical parts. Input Devices are devices used to gather information about the system, which consists switches (toggle switch) and sensors, in order to feed the controller (Arduino) by an information about the belts status and objects to be carried. The controller, which is the main element that operate the whole system, uses the information from the sensors which takes the counting and movement decision prior to sending the orders to the output devices by the actuators and the relays. Output Devices are the actuators that converts an electrical signal into mechanical movement 1.1 Methodology The main purpose of this model is to reduce cost and time of cutting operation. Conveyor for transmission of sheet is used. Here the cutting assembly will cut cardboard sheet at a point and due to pressure applied by rollers the sheet will cut automatically in that direction. To transfer power gear drive with pulley is used. Our main aim while manufacturing is to reduce frictional losses and maintain the speed of motor to maintain proper friction in between roller and the paper. Also, the paper should pass without slipping for the proper cutting. The overall cost of project is to be minimized by using complementary materials then actual heavy industrial material. DNS Test The DNS test is very simple method for production control. The sample preparation procedure is: -Cutting two notches on a paperboard sheet, one from each side of the specimen separated by a distance L. The cut was made by a razor blade to half the paperboard thickness h/2. Prior to cutting, the paperboard was placed on a movable x– y table, and the razor blade was fastened onto a movable stage. Hence, very precise notches could be made. -Cut 15 mm wide notched specimens from the paperboard sheet; comparable to the method for in-plane tensile testing. The maximum stress measured was used to calculate the maximum shear stress in the specimen. The double notches generate stress concentrations that result in quite uniform strain fields. The double grooves produce a stress concentration resulting in a fairly uniform strain field. It can be concluded that, for the typical elastic properties of paper materials, the shear stress distribution is quite uniform. In addition, Whitney's analysis shows that the shear stress distribution is related to the length of the shear zone, L. As L decreases, the shear stress distribution becomes more uniform, for the parameters, resulting in a rather flat stress profile. Therefore, the notch effect is small.In addition, due to the structure of the fiber network, cardboard is less prone to cracking in thickness than homogeneous materials. Maximum shear stress insensitiveto cracks in the MD-CD plane. 1.2 Components Arduino- It is an open-source proto type based on easy-to- use hardware and software. It consists of a circuit board an be programmed and software called Arduino IDE can be used to write and upload the computer code to the physical board. Motor- Motor selected is AC Single Phase Induction motor. We use the single-phase power system more widely than three phase system for commercial purposes, domestic
