The following aspects should be considered in monitoring the cutting process:
Machining process monitoring roughing is the primary consideration of the workpiece surface of the excess margin of rapid removal. In the active machining process of machine tool, according to the set cutting parameters, the tool is active cutting according to the predetermined cutting track. At this time, the operator should pay attention to the change of cutting load in the process of active machining through the cutting load table, according to the bearing capacity of the tool, adjust the cutting dosage, play the machine power. In the active cutting process, the general beginning of cutting, the sound of the cutting workpiece is stable, continuous, light, at this time the movement of the machine tool is stable.
With the progress of the cutting process, when the workpiece has a hard point or tool wear or tool send clip and other original, the cutting process is unstable, unstable performance is the cutting sound change, with the workpiece will show each other impact, the machine will show a sensation. At this time should be timely adjusted cutting parameters and cutting conditions, when the adjustment effect is not obvious, should suspend the machine tool, check the tool and workpiece conditions of the finishing process monitoring finishing, the first is to ensure the workpiece machining size and machining surface quality, high cutting speed, large feed. At this time, attention should be paid to the impact of debris accumulation on the surface of machining. On cavity machining, attention should also be paid to the corner machining of cutting and letting the knife.
To solve the above problems, one is to pay attention to the adjustment of the cutting fluid spray orientation, so that the cnc machining surface is always in cooling conditions; Second, we should pay attention to investigate the quality of the machined surface of I parts, after adjusting the cutting parameters, as far as possible to avoid the change of quality. If the adjustment still has no obvious effect, it should stop to check whether the original program is reasonable. Special attention is, in the pause to view or stop to view, to pay attention to the position of the tool. If the tool stops in the cutting process, the sudden spindle stops, the workpiece surface will produce the mark. Generally should be in the open cutting state, consider shutdown. The quality of the monitoring tool determines the machining quality of the workpiece to a large extent. In the active machining cutting process, after sound monitoring, cutting time control, cutting process to pause to view, the workpiece appearance analysis and other methods to distinguish the normal wear and abnormal damage of the tool. According to the machining requirements, timely machining of the tool, to avoid the occurrence of machining quality problems caused by the tool is not timely machining.
With CNC machining as the core technology, Asset Metal technology limited owns physical factories and testing equipment, and integrates the manufacturing resources of rapid prototyping, mold, post-machining, etc., to provide customers with rapid proofing, small and medium-sized batch manufacturing and trial assembly, and truly achieve a one-stop service that saves worry and effort.
