The laddu shaper machine is primarily utilised in cottage and small-scale industries. A feed hopper, screw conveyor, roller, motor, and collecting tray are some of its various parts. People frequently order a lot of sweets from the vendor and anticipate receiving them as soon as feasible. The vendor must add more staff in order to finish the order in the allotted time and also maintain the quality of the product. To cope up with demands to be fulfilled in a shorter time span, automation can come in handy. The effort to automate laddu production is discussed in the paper. By enhancing production rate and quality, the project seeks to decrease labour costs while boosting profits. Additionally, it adheres to safety standards for the materials required to build the machine, reducing material waste caused by manual handling. The material used is food grade material to keep the machine hygienic and corrosion-free. The purpose of this machine is to make proper and highly nutrients content laddu in proper round shape.

The paper contains a detailed analysis of dynamic behavior of cylindrical roller bearings for unbalanced rotor conditions due to speed variations and internal clearances. The system behaves nonlinearly due to various reasons such as stiffness and damping at the contact points (due to Hertzian contact force between rollers and races), radial internal clearance, and speed associated with unbalanced rotor force. Presently, the differential equations that show the dynamics of the cylindrical roller bearings have been obtained using Lagrange’s equation and solved numerically using modified Newmark-beta method. The tools like orbit plots, phase portraits, Poincare maps, and FFT plots are helpful for analyzing various motion behavior. The obtained response showed the sensitive behavior of the system from periodic to quasiperiodic and chaotic with speed and clearance variations for unbalanced rotor conditions. The analysis is an attempt to show an interaction between existing frequencies due to change in speed and clearance variations, which will be helpful for analyzing the current condition of a healthy cylindrical roller bearing.
