The WPE FORGE MASTER program is designed as an aid to forge masters who want to develop pass schedules for bar forging. • Outputs forging pass schedules to maximizing press time Description An experienced forge master can develop a geometrical pass schedule quite easily, however; the optimization of a pass schedule to minimize forging time is quite difficult as it involves the consideration of numerous factors which influence the production rate. All of the important factors including spread behavior, die geometry and the speeds of the press and manipulator(s) are considered by the program. The required pressing force relative to the material resistance is calculated as a function of the instantaneous temperature and compared to the maximum available press force. | ||

The pass schedule is calculated from three sets of entered values - Machine Data, Material Data and Forging Data. Machine data includes information about the press and manipulator(s). Material Data includes information about the part being forged such as spread behavior, hot yield, and maximum reduction. Forging Data includes ingot weight, start and end dimensions, handling times, cornering and planishing. (for further information regarding the calculation basis see Fundamentals of Programmed Forging by H.J. Pahnke) | ||||||||||||||||

Machine Data and Material Data may be saved and opened as separate blocks of variables. The entire project including the Forging Data may be stored and opened at any time. The pass schedule calculated is displayed on the screen and can be stored for immediate use by the press operator. The schedule may also be printed locally or on a network printer. Material rigidity curves may be generated on the plotter screen. These curves also reflect the minimum and maximum forging temperature for the material. Coordinates derived from test forgings may also be manually entered and plotted. The Rigidity factors and minimum/maximum forging temperatures from the test coordinates can be automatically transferred to the material data. The program is a Windows application written in an object oriented language. Operation of the program does not require any special skills in metal forming or development of forging schedules. Hardware requirements include: * PC with Pentium II or higher processor (or equivalent) .
