Worldwide Environmental concerns have placed pressure on the development of low and zero emission vehicles. Legislations in different countries are bringing ever more stringent requirements on new vehicles. At the current time the zero emission requirements can only be met by batteries, with fuel cell technology still in development. The problem with the batteries is their low power density compared to fossil fuels. For this reason, the hybrid electric vehicle concepts have grown to meet the low and the ultra low emission requirements. Highlights and Distinguished features of the Hybrid system designed by A T Consultants. The Hybrid systems are designed either on parallel or on series systems. Our system is a series system.A specially designed High speed AC induction motor is used in the system.

This is a specially designed CNC Roll Groove Turning machine used for turning of the three rolls fitted to the SRM – Stretch Reducing Millstands used in the PQF mills. The rolls are machined in an in situ condition on the stands meaning that the rolls are not taken out of the stands for machining but all the three rolls are machined in the assembled condition in the stand under the required accuracies. The concentricity of all the three grooves, root diameter of the rollers, centering of the stand etc is taken into consideration for the accuracies of the stand to produce a perfect pipe on the PQF mill. The stands are used in order to maintain the sizing, finishing and to control the geometrical tolerances of the pipes. The machine is used to redress the worn out surfaces of the rollers in the SRM stands to achieve the required accuracies on the pipes. Once the rolls are machined, the same stands can be used in the PQF mills for producing the required pipes. Therefore it is also called a Callibration machine. Special cycles are developed for machining these rolls on the stands. The cycle uses interpolation of the axes to get the machining done. Specially designed probe cycle us also used to assess the pre and the post machining parameters. A combination of mathematical formulas, intense mathematical calculations and features of a high end CNC comtroller used to program the cycles has been successfully designed to meet the requirement of this application.  The result of using this machine for calibrating the stands is extraordinary in terms of accuracy on the end product – the pipes, and in terms of the time taken in getting the job done which is highly productive and in turn profitable to the company.
