Description
Technical field
The present invention relates to annular groove turning technical field, specially a kind of processing method of annular groove.
Background technology
In numerical control Vehicle Processing, processing groove, such as seal groove, Gewindefreistiche, grinding wheel groove are frequently encountered, it is also frequent
The positions such as processing bearing oil duct.When these positions are processed, many methods using " feed-withdrawing " in industry, in feed process
In, NC cutting tool gradually convergence programming point performs withdrawing order when cutter reaches the coordinate of program.As shown in figure 1,
Cutter reaches program command coordinate（Design the bottom of groove）, workpiece do not rotate a circle also, and cutting tool is not also by bottom land
The allowance removal in portion, causes trench bottom still to leave allowance, so as to produce size phenomenon less than normal.Therefore have to
Program or knife bowl spares are compensated, and influence processing efficiency, reduce product percent of pass.
The content of the invention
It is an object of the invention to provide a kind of processing method of annular groove, solve processing these spot sizes be less than normal to ask
Topic,.
Above-mentioned technical purpose of the invention technical scheme is that：A kind of processing side of annular groove
Method, comprises the following steps：
（1）Workpiece is rotated along axis, and workpiece rotational frequency is n；
（2）Feed, lathe tool carries out turning to workpiece along the radial direction movement of workpiece, and lathe tool is moved to design ring along direction of feed
The trough line of shape groove, makes the front end of lathe tool be overlapped with the trough line of design annular groove, and the depth for designing annular groove is L；
（3）Stop knife, carry out stopping knife when the front end of lathe tool overlaps with the trough line of design annular groove, the residence time is t seconds, t=
1.5/（n/60）；
（4）Withdrawing, lathe tool is exited in annular groove.
Wherein the unit of rotating speed n is r/min, and the unit of L is mm.It is general to produce during the feed of existing technology
Both situations, one is NC cutting tool gradually convergence programming point, and withdrawing life is immediately performed when cutter reaches the coordinate of program
Order, now workpiece does not rotate a circle also, and cutting tool does not also remove the allowance of trench bottom, causes trench bottom still to stay
There is allowance, so as to produce size phenomenon less than normal；Two be cutter reach program coordinate after stop the regular hour hold again
Row withdrawing, stops too short being easily caused and does not remove allowance completely, and residence time long influence processing efficiency accelerates cutter mill
Damage and influence workpiece surface roughness.In the present invention, knife time t=1.5/ is stopped（n/60）, the time determined by the rotating speed of workpiece
It is fixed, make rotating speed it is fast stop that the knife time is few, rotating speed it is slow to stop the knife time more, both ensure to remove allowance completely, can guarantee that again plus
Work precision, improves surface roughness, moreover it is possible to reduce the unnecessary abrasion of cutter.
Preferably, feed velocity of the lathe tool withdrawing speed more than lathe tool.
Preferably, feed velocity v1, lathe tool withdrawing speed v2, the v2=v1+a*v1 of the lathe tool, wherein a's
It is 1-5 to be worth.The unit of v1 and v2 is m/min.
Preferably, the step（1）In turning include rough turn and smart car, rough turn feed velocity being entered more than smart car
Knife speed.
Preferably, the step（1）In allowance be 0.6mm-1.2mm.
Preferably, it is described stop between knife step and the withdrawing step also to include pre- withdrawing step, again feed step and
Stop knife step again.The step can effectively remove allowance and mismachining tolerance, listen machining accuracy and surface roughness.
Preferably, lathe tool leaves the trough line 0.3mm-0.6mm of design annular groove in the pre- withdrawing step.
Preferably, the feed velocity of lathe tool is less than the feed velocity of smart car in the step of feed again.
Stop knife step again preferably, described, the residence time of lathe tool is 0.5t-0.8t.
Beneficial effects of the present invention：The present invention can effectively solve the problem that and process these spot sizes problem less than normal, so as to keep away
Artificial modification program is exempted from or has carried out knife benefit, improve machining accuracy, determined by the rotating speed of workpiece due to stopping the knife time, turned
Speed is fast to stop that the knife time is few, rotating speed it is slow to stop the knife time more, both ensure to remove allowance completely, machining accuracy is can guarantee that again,
Improve surface roughness, moreover it is possible to reduce the unnecessary abrasion of cutter.
