Abstract
The invention relates to a numerical control machining deburring method, belongs to the field of machining, and relates to an improvement on a part deburring method. The method includes the steps that the shape of a part is machined through a machine tool according to the design requirement; a three-dimensional diagram is drawn through UG software according to the part specification size of the design requirement, wherein the edges of the three-dimensional diagram are coincident with the part edges of the design requirement; post-processing is carried out through the UG software, and an obtained tool track is converted into machine-tool recognizable program codes; an inverse R milling tool is selected, the placement coordinate system of the tool and the part on the machine tool should be coincident with the coordinate system in the UG tool track, and the machine tool carries out machining through the recognizable program codes and the inverse R milling tool; and polishing is carried out, and the edges of the part obtained in the step six are slightly polished through abrasive paper. According to the method, the proper tool is selected, a numerical control deburring program is compiled through a three-dimensional model, the traditional manual deburring machining method is changed, the part deburring machining efficiency and the part deburring quality stability are improved accordingly, and high practical application value and large economic benefits are achieved.
Description
Technical field
The invention belongs to field of machining, relate to the improvement to part burr removing method.
Background technology
The processing of current External Shape generally adopts the mode of forging milling, in the process of forming parts, removes material in a large number, inevitably produces burr, and these type of burr naked eyes intuitively can be distinguished, position is exposed.Tradition burr removing method mainly adopts file, scraper, oilstone, edger manual mode, is applicable to the roughing of simple External Shape, die cavity.These class methods opponent work operator, workload is large, and efficiency can not show a candle to digital control processing, makes deburring become the bottleneck operation of production; Meanwhile, manual deburring relies on operator's level of skill, and the part status uniformity processed is poor, easily produces the problem of appearance such as scuffing, affects product quality.
Summary of the invention
The object of invention: for solving existing processing method inefficiency, the problem of quality stability difference, provides a kind of numerical control burr removing method efficiently, ensures that rounding uniformity is good simultaneously, and there will not be scuffing.
The technical scheme of invention: digital control processing burr removing method, for profile and die cavity burr, according to three-dimensional part model, at Part Surface Roughness planarity requirements high, special-shaped chamber depth as shallow not easily manual operations, seal groove peripheral position, by UG software midplane profile module establishment deburring numerical control program.Coordinate anti-R cutter/ball cutter, can realize running deburring program on machining equipment.
Concrete procedure of processing is as follows:
Step one: use machine tooling to go out part by designing requirement;
Step 2: use UG software according to the part specifications size drawing three-dimensional figure of designing requirement, graphics seamed edge should be consistent with the part seamed edge of designing requirement; Described UG software is the UnigraphicsNX system of EDS Company.
Step 3: enter UG face profile module, selects the graphics seamed edge wanting deburring in " specified parts border " hurdle; The upper side wanting the graphics seamed edge of deburring is selected in " appointment bottom surface " hurdle; In " cutter " hurdle, the anti-R milling cutter milling cutter of recessed R (the described anti-R milling cutter to be tool arc be) both sides arcuate midway point line value D1 is input in tool diameter, graphics seamed edge is carried out cutter path establishment, and cutter path coordinate system is consistent with the actual Cutter coordinate system of lathe;
Step 4: carry out postpositive disposal by UG software, cutter path step 3 calculated converts lathe recognizable programs code to;
Step 5: select anti-R milling cutter, tool diameter is D, and anti-R circular arc is r, and in step 3, tool setting is carried out in D1 position, by tool setting length input lathe;
Step 6: the coordinate system that frock, part are put on lathe is consistent with the coordinate system in the UG cutter rail described in step 3, lathe uses the anti-R milling cutter obtained in recognizable programs code described in step 4 and step 5 to process;
Step 7: polishing, uses the part seamed edge place of 1000 object sand paper described in step 6 gently to throw.
The advantage of invention: immediately can carry out deburring after Milling Process part, a large amount of shortening single-piece work time, can completing with operation, without the need to increasing the deburring operation of repeatability again, solving artificial deburring efficiency and quality problems; Efficiency improves more than 90%, and die cavity outward appearance scratches and is down to 0, and processing the trailing edge is round and smooth regular; Again without the need to relying on operator's level of skill, effectively avoiding scratching, operation can be reduced simultaneously and change a job in transportation and remain by burr the bump injury caused.
Accompanying drawing explanation
Fig. 1 is flow chart of steps of the present invention;
Fig. 2 is anti-R milling cutter schematic diagram.
Detailed description of the invention
Concrete procedure of processing:
Step one: processing parts profile.
Step 2: the accessory size after using UG software to process according to step one carries out drawing three-dimensional figure, and graphics seamed edge is consistent with the seamed edge of part to be processed.
Step 3: see Fig. 2, enters UG face profile module, selects the seamed edge wanting deburring in " specified parts border " hurdle; Select above seamed edge in " appointment bottom surface " hurdle; In " cutter " hurdle, anti-R milling cutter (milling cutter point of a knife is that recessed R is referred to as anti-R cutter) both sides arcuate midway point line value D1 is input in tool diameter, seamed edge in step 2 is carried out cutter path establishment, and cutter path coordinate system is consistent with actual Cutter coordinate system.
Step 4: carry out postpositive disposal by UG software, cutter path step 3 calculated converts lathe recognizable programs code to.
Step 5: select anti-R cutter, tool diameter D, anti-R circular arc r, carry out tool setting, in step 3, tool setting is carried out in D1 position, by tool setting length input lathe.
Step 6: the coordinate system of frock, placing part is consistent with the coordinate system in step 3 UG cutter rail, uses the anti-R cutter in the program of step 4 acquisition and step 5 to process.
Step 7: polishing, uses 1000 order sand paper part seamed edge place after processing gently to throw.
