CNC Machining time balance processing efficiency measures to improve

Dual-turret lathe with a workpiece with the processing, if the use of different techniques, the efficiency will be a lot of difference. Here is the core cycle time that the balance between processing time. Among them, one before and after the two processes balance between the processing time, two on each procedure is the next tool balance between the processing time. If the measures are reasonable, and ergonomics can improve much.
Figure 1 and Figure 2 shows an inner ring bearings when turning before and after the two processes. The former process, T1, T2 on a knife mounted on a turret, T3, T4 tool loaded on the next; after the process, T1, T2, T3 on knife mounted on a turret on, T4, T5, T6 turret knife mounted on the next .

The original scheduling process in accordance with conventional methods, the former process a little knife in the T3, and then processes the figure of a T7 many knife (actually a knife before the transfer process from the T3), that is, part of ribs on Rough ③ After the process turning. At that time before the process cycle time is 61s, after the process cycle time is 89s. This work is a high-volume processing, before the process is very loose, very tight after the processes, the impact of processing efficiency. The first measure is a knife after the process shift to the former process, as shown. Processes with the former three knives, a knife that is fitted Units two knives, and the other a knife blade mounted the platform, no matter how arranged, the upper and lower turret of the processing time can not be balanced. Now on, the next tool after the installation of two knives, and then cutting route reasonable arrangements to enable the upper and lower end of tool cutting almost simultaneously at the same time back knife. This former process cycle time down to 72s, then after the process cycle time is 78s.
Thus, the processes on the upper and lower knives to cut the time it is a balance, and before and after the process is still an imbalance of processing time. Observed that after the processes of the upper and lower turret processing time, an early end, a great difference between the end of the evening. Thus, after the process at 6 of the knife, on three packed in tool holder, the next three turret mounted under the premise of the program to do the four types of cutting through the calculation and the actual cutting, select this option now: to make up, At the same time, under the basic tool and back end of the cutting knives, cycle time is 72s. At this point, not only before and after the process on their own, under the tool processing time to reach a balance, but also before and after the process cycle time to achieve the balance. Can also say that this is the best option.
If the pre-and post-process the composition of a production line, then the cycle time of this line from the original 89s, now reduced to 72s, a 19% shorter processing time, so that improved ergonomics.
