Description

A kind of NC Milling method of annular groove
Technical field
The present invention relates to the NC Milling method of the annular groove in machining field.
Background technology
Being frequently encountered in actual production life needs to process inner groove on the inner hole wall of part or in the outer of part The situation of outer groove is processed on cylinder, general degree of precision, roughness annular groove high processing are processed using numerical control turning mode more, but Especially asymmetric larger shape part should not use numerical control lathe processing mode to asymmetric part, while also cannot be by boring-mill work Mode is realized, and takes more process time, processing efficiency using the general NC Milling method that T-shaped milling cutter repeatedly enters withdrawing It is not high.
The content of the invention
It is an object of the invention to provide a kind of NC Milling method of annular groove high in machining efficiency.
In order to solve the above problems, the technical scheme is that:
A kind of NC Milling method of annular groove, is comprised the following steps, the first step, and parts to be processed is installed in processing On the workbench of the heart, workbench is set to be coaxially set with the inner hole wall or outer cylinder of parts to be processed;Second step, workbench and T-shaped milling cutter on machining center turns clockwise under the driving of respective actuating unit, and T-shaped milling cutter radially enters towards parts to be processed Knife, the depth of radial feed is identical with the groove depth of the annular groove of required processing;3rd step, after worktable rotary at least one week, T The feed vertically of type milling cutter, vt≤h in the step, v represent the rotary speed of T-shaped milling cutter, and t represents that T-shaped milling cutter rotates a circle institute The time for needing, h represents the thickness of T-shaped milling cutter;4th step, the groove width phase of the length of axial feed and the annular groove of the required processing Stop axial feed with rear, workbench at least rotate a circle after withdrawing.
Beneficial effects of the present invention are:In the present invention, workbench drives parts to be processed rotation, while T-shaped milling cutter is along axle To feed, T-shaped milling cutter is helix with respect to the movement locus for parts to be processed, also imply that the shaping of whole annular groove compared with For continuous, good surface quality and machining accuracy can be obtained, T-shaped milling cutter completed by only carrying out a withdrawing annular groove plus Work, saves process time, there is provided processing efficiency.
Brief description of the drawings
Fig. 1 is the cooperation schematic diagram of parts to be processed and workbench in the present invention;
Fig. 2 is forward and back knife schematic diagram of the invention;
Fig. 3 is movement locus figure of the T-shaped milling cutter with respect to parts to be processed in the present invention.
Specific embodiment
The implementation of a kind of NC Milling method of annular groove is for example shown in Fig. 1 ~ 3:A kind of NC Milling method of annular groove, Comprise the following steps, the first step, parts to be processed 3 is installed on the workbench 1 of machining center, parts to be processed is asymmetric Part, makes workbench be coaxially set with the inner hole wall of parts to be processed;Second step, workbench and T-shaped milling cutter 4 are each automatic Force mechanisms are turned clockwise under driving, and T-shaped milling cutter is installed on the cutter shaft of machining center, and T-shaped milling cutter is towards parts to be processed footpath To feed, the depth of radial feed is identical with the groove depth of the annular groove 2 of required processing;3rd step, in worktable rotary at least a week After, T-shaped milling cutter feed vertically, vt≤h in the step, v represents the rotary speed of T-shaped milling cutter, and t represents T-shaped milling cutter rotation Time needed for one week, h represents the thickness of T-shaped milling cutter;4th step, the length of axial feed and the annular groove of the required processing Groove width it is identical after stop axial feed, workbench at least rotate a circle after withdrawing.A represents T-shaped milling cutter in non-radial feed in figure When position, B represents the position after T-shaped milling cutter radial feed in figure, and C represents the position after T-shaped milling cutter axial feed in figure, D represents the position after T-shaped milling cutter withdrawing in figure.
Vt≤h will not produce omission machining area when can ensure that T-shaped milling cutter is processed, if the axial feed of T-shaped milling cutter Excessive velocities, may just occur some undressed regions omitted, therefore in general, the value of vt is got over less than h, processing Quality can be better.Due to workbench rotate when, T-shaped milling cutter simultaneously axial feed, so T-shaped milling cutter is relatively to be processed The movement locus 5 of part is helix, and the processing of annular groove is continuous, and the surface quality and machining accuracy of processing are higher;Make by contrast After this NC Milling method, process time of each part saves 7 ~ 15%, the present invention save the length of process time with The groove width of the annular groove of required processing is relevant with the thickness of T-shaped milling cutter, and the groove width of general annular groove is bigger, and the thickness of T-shaped milling cutter is smaller, The time saved is more long.Axial feed in above-described embodiment both can be by axial feed under upper, again can axle from the bottom to top It is in the present embodiment that inner groove, certainly in other embodiments of the invention, this method are processed on inner hole wall to feeding Can be used for processing outer groove on the outer cylinder of part;Certain this method applies also for the processing of symmetrical component.
