Description
Technical field
The present invention relates to machining technique field, especially a kind of milling method for chill product.
Background technology
Milling Process includes roughing and finishing；Roughing is for the purpose of quickly cutting off blank allowance, in roughing
When should select the big amount of feeding and cutting depth as big as possible, to cut off chip as much as possible in the short period of time；
Roughing Surface Quality it is less demanding, the blunt Standard General of cutter is significantly increasing for cutting force, i.e., after knife face
Abrasion width VB is standard；Finish main consideration be workpiece surface quality rather than chip number, lead to during finishing
Frequently with small cutting depth, the front cutting edge of cutter often has special shape, such as wiper edges.According to used machine
Bed, cutting way, workpiece material and the cutter used, can make surface roughness reach Ra1.6 μm of level, fabulous
Under the conditions of even can reach Ra0.4 μm；In finishing, the wear extent of knife face is no longer main standard after cutter, and it will step down
In the surface quality of workpiece.
Processing mode includes climb cutting and upmilling；During upmilling, the thickness of cutting of cutter tooth gradually increases from zero；Cutter tooth is starting to cut
Fashionable, due to the influence of rounded cutting edge radius, cutter tooth is skidded on the surface of the workpiece, and generation is compressed and rubbed against, and makes this section surface
Produce serious chilling layer；When sliding to a certain extent, cutter tooth can cut layer of metal layer；During next cutter tooth incision, again
Extrude, slide on chilling layer, cutter tooth is easily worn and torn, while increasing workpiece surface roughness value；Therefore upmilling mode meeting
Some side effects are produced, such as wear of the tool flank is accelerated to reduce blade durability, and surface is produced when processing high-alloy steel
Hardening, surface quality is undesirable etc., thus processing in it is rarely needed；During climb cutting, the thickness of cutting of cutter tooth is gradually passed from maximum
Reduce to zero, it is to avoid cutter tooth extruding during upmilling, slide phenomenon, the work-hardening capacity of machined surface is considerably reduced, surface
Quality is also higher, tool life also than upmilling when it is high, the cutting component of vertical direction presses to workbench all the time, it is to avoid workpiece
Vibration；Climb cutting mode be for obtain good surface quality pass through frequently with processing method；It has less rear knife face
The advantages of abrasion, lathe operate steadily, it is adaptable to process high-alloy steel under preferable machining condition.
The power consumption of climb cutting is smaller than upmilling, under equal machining condition, and climb cutting consumption power will low 5%-
15%, while climb cutting is more beneficial for chip removal；General processing uses climb cutting as far as possible, to improve the finish on part to be processed surface,
Ensure the precision of size；But when having hard layer, accumulated slag, workpiece surface uneven more significant on cutting face, should not use
Climb cutting because blade at this moment must from outside by workpiece hardened layer, so as to produce stronger abrasion, should use inverse
Milling.

The speed of travel of cutter 2 of wherein climb cutting processing is 145~216mm/min, and the speed of travel of cutter 2 of upmilling processing is
90~160mm/min.
As shown in Fig. 2, Fig. 5, the rotating speed of cutter 2 of climb cutting processing is more than the rotating speed of cutter 2 that upmilling is processed.
The speed setting of cutter 2 of climb cutting processing and upmilling processing is 100~240r/min.
The rotating speed of cutter 2 of wherein climb cutting processing is 150~240r/min, the rotating speed of cutter 2 of upmilling processing for 100~
180r/min。
Using the milling method of chill product of the invention, its advanced and novelty have it is following some：Feed mode
Upper use circular arc feed is alleviated in cutter incision workpiece fabrication, and each blade is protected in the direct impact of cutter blade and workpiece
Tipping, does not reduce the heel and toe wears such as cutter tipping, adds cutter life；Entered by original cut and be changed to soft cut
Enter, each transmission mechanism between cutter and machine motor and cutter is hit and is decreased obviously, the feed mode is not only effective
It is service life to improve cutter, also the service life of lathe is virtually being improved, for expensive large scale equipment
For, in terms of extension device service life, with obvious realistic meaning；Effectively reduce going out for blade tipping phenomenon
It is existing, when last knife process, it is ensured that each cutting edge it is complete so that each blade is uniformly cut, and workpiece has been effectively ensured
Accurate to dimension and finished surface the surface quality such as roughness.
The cutter incision workpiece of circular arc feed is the part of one sword of cutter or a part for multiple swords, is not only beneficial to
Cutting is lower to consider to be worth doing, moreover it is possible to alleviates the instantaneous stress impact of blade, is bidirectional protective to blade, resultant effect evaluation, which can improve cutter, to be made
With the life-span about 10%；Cutting force is smaller during cutting workpiece, about reduces by 15%, resistance reduces, and cuts more brisk, equal workpiece is removed
During amount, reduction machine motor energy consumption about 5%.
The cutter moment cutting of circular arc feed is that the segment section of part edges is being cut, and contact area is more scattered, is easy to
Chip removal, it is to avoid the scuffing of iron filings discharge not freely to machined surface, to the final surface quality of workpiece has more preferable protective effect；
When cutting or cutting out workpiece, blade instantaneous touch area relatively disperses, and cutting force is smaller, and the cutting heat produced during cutting is less,
Cutting fluid can fully reduce the temperature at cutting position simultaneously, and along with chip removal effect is good, iron filings can take away more cutting heats,
The temperature rise of workpiece is greatly reduced, adverse effect of being expanded with heat and contract with cold to elimination, it is ensured that high-accuracy workpiece final size is extremely advantageous logical
The improvement to numerical control boring Milling machine cut modes is crossed, cutter life about 10% is improved, and for flat face size and right
The form and position tolerances such as title degree there has also been obvious raising, effectively reduces the quality meaning caused by surface quality is unqualified and does over again
Reprocess, save boring Milling processing integrated costs about 3%~5%.
Circular arc feed can also run each boring Milling processing of knife, can be by feed mode as long as possessing digital control processing condition
Optimize；Further, it is also possible to which circular arc feed mode is expanded to numerical control workshop, some high-precision turnery processings are particularly
Situations such as, with more obvious effect
