Embodiment Construction

[0027] figure 1 It is a schematic diagram of CNC cutting machining parameter control in the prior art. As shown in the figure, the machining parameters are pre-set, mainly including two types, namely feed override and spindle override. When the switch is used to adjust the feed override and spindle override, the feed override switch and the spindle override switch need to be adjusted separately. The feed override switch and the spindle override switch each have multiple gears to choose from, but the values ​​of the preset multiple gears generally do not change, and the user can only select a certain range within the preset gear range. first gear. The feed override and the spindle override are independent of each other, and only the feed override or the spindle override can be adjusted independently during the machining process. The separate adjustment of feed speed and spindle speed in the existing technology may cause huge fluctuations in the actual tool feed per tooth. Too...

Abstract

The invention provides a ratio control method for realizing different processing strategies. The ratio control method includes that a processing strategy table is preset according to processing needs, each strategy on the processing strategy table corresponds to at least one group of processing parameters; a control panel transmits selection information of the processing strategy to a PLC (programmable logic controller) module according to selection input of a user; the PLC module acquires the group of processing parameters under the processing strategy and transmits the acquired processing parameters to a CNC (computer numerical control) module; the CNC module calculates spindle speed n' and feed speed vf'; the CNC module converts the spindle speed n' and the feed speed vf' into servo drive instructions to be outputted. Due to the fact that one processing strategy is needed to be selected to adjust various processing parameters to achieve the processing purpose, the ratio control method is convenient and simple to operate, and the technical defect that the various parameters adjusted separately are easy to cause accidents can be overcome.

Description

technical field [0001] The invention relates to the field of numerically controlled machine tools, and more specifically, relates to a method for controlling magnification to realize different machining strategies. Background technique [0002] CNC cutting in the field of CNC machine tools is an important production method in the field of machinery manufacturing. In the process of CNC cutting, in order to obtain the final workpiece, the operator needs to set the processing parameters (spindle speed, feed speed and feed depth) according to the actual processing situation, and needs to change the processing parameters according to different processing requirements during the processing. parameter. [0003] In the existing CNC cutting technology, the main focus is on the two processing parameters of spindle speed and feed speed, and the spindle speed and feed speed are generally input by adjusting the selection switch (such as a band switch). Use the spindle speed switch to a...
