· The way I calculate cycle times in my head is to take 250 times the wall thickness of the part, which gives me a target cycle time in seconds. For example, if I have a part with a .100-inch nominal wall, I multiply .100 inch by 250, which gives me a 25-second cycle. If the existing cycle time is 25 or 30 seconds, then I leave it alone.
In grinding operation, elastic deformations of the grinding machine and the grinding wheel induce a residual stock removal of workpiece. On the other hand, thermal expansions of the workpiece and the grinding wheel increase the …
· CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM …
· It is often necessary for CNC people to determine how long machining operations will take to perform. You may be trying to determine which of two or more processes will be used to machine a workpiece - or you may just be wondering how long a machining operation will require to complete. Frankly speaking, the formulae related to calculating machining time are pretty …
· Grinding wheel speeds should be maintalned with-in a range of 5000 to 6500 feet per minute (1525 to 1980 meters per mm), unless special conditions prevall or equipment and wheels designed for substantially higher wheel speeds are used.
· 1 Calculate the power required per mm3 of metal removed per second for a surface grinding operation using the following data. Wheel speed = 50 m/s work speed = 0.2 m/s, tangential force = 90N. Depth of cut =0.02mm and width of cut = 15mm. 2 During external cylindrical grinding following observations are made Diameter of work piece = 50mm.
In the grinding process, due to the elastic deformations of grinding machine and grinding wheel, the ground depth of cut is smaller than the applied depth of cut. Consequently, the ground depth of cut has to be controlled in spark-out grinding process. However, the cycle time in spark-out grinding process is not easy to be estimated. From such a viewpoint, in this study, using …
