CNC lathe controller capable of automatically setting thread retracting distance and angle

Abstract

The invention relates to a CNC (Computer Numerical Control) lathe controller capable of automatically setting a thread retracting distance and an angle, which at least comprises a thread circulation simulation kernel module and a retracting treatment kernel module, wherein the thread circulation simulation kernel module conducts dynamic simulation through a thread circulation machining path generation unit and a thread dynamic behaviour simulation unit before doing an actual turning action, so as to master a dynamic behaviour during actual workpiece turning; and the retracting treatment kernel module transmits motion information recorded by the thread circulation simulation kernel module to an effective thread optimization unit, a retracting computation unit and a thread retracting path adjustment unit, so as to plan an appropriate thread circulation retracting action. A user is not required to designate the thread retracting distance and the angle during thread circulation, and the controller can automatically optimize the effective thread length while avoiding retracting vibration.

Description

technical field [0001] The invention relates to a CNC lathe controller capable of automatically specifying the retracting distance and angle, and belongs to the technical field of CNC lathe equipment. Background technique [0002] Traditional lathe cycle action, such as figure 1 As shown, before the execution, the user must manually operate and input the tool retraction distance 11 and the tool retraction angle 12 before the actual turning process can be performed. At this time, if the retracting distance set by the user is insufficient, it may cause the vibration of the retracting tool, causing damage to the lathe mechanism and reducing the service life of the machine. In order to avoid the above phenomenon, the user should moderately increase the set retraction distance, but if the distance is overly enlarged, the effective tooth segment length will be limited. Therefore, the lathe user may have to adjust the retraction distance several times in order to avoid the vibrat...

Problems solved by technology

In other words, the fact that it is difficult for lathe users to set the tool retraction distance and tool retraction angle under the condition that both the quality of turning teeth and the service life of the machine must be taken into account will seriously cause low production efficiency
