MACHINING PARAMETERS OF TURNING OPERATIONS

Using a simple static nonlinear relationship between cutting temperature and cuttingvelocity similar to Equation (6.17), with c = 0, a self-tuning regulator was developed to control thecutting temperature via adjustment of the cutting velocity.6.6 Future Directions and EffortsThis chapter has[r]

situation is that surface texture continuously degen-erates, and it is only the burnishing (i.e.‘ironing’) of the surface that ‘masks’ the temporary improvement in machined surface – more on this topic will be made in the surface integrity section. What is apparent from using the AWT techniqu[r]

Total Energy Requirement The total energy requirement for processing any quantity of poultry is the sum of the energy components involved in each process. Thus the total energy ET becomes: ET = Es + Esd + Ee + Ewc + Ep (6) With eq 6, it is possible to determine the total energy consum[r]

Moreover, we show how basic synchronization mechanisms like locksynchronization or condition synchronization can be used to build mo[r]
