Background technology
Thin-wall part planform is complicated, and shape coordination is more demanding, and part contour dimension relative cross-section size is larger, processing
Surplus is big, relative rigidity is relatively low, and processing technology is poor, and required precision is high, is easily deformed, directly affects in process
The raising of thin-wall part mass production yield rate.The research carried out for the high-speed milling technique of aerolite structural member is current
Although having there is more report, the problem of such or such is still had in actual production process, particularly certain is large-scale
The high-rate wireless LAN technological process of thin-wall part inner wall and problem on deformation are still the reason that puzzlement improves processing efficiency.
Processing for large thin-wall inner surface, the particularly processing with the irregular element such as inner mesh, turning, boring
It is all helpless the processing methods such as to cut, now widely used rose cutter method for milling is because its processing efficiency is low, tool wear
Serious wait all limits its practical application.
This problem can be well solved using flat-end cutter orthogonal turn-milling processing method.
Invention content
The purpose of the present invention is to provide a kind of interior rotary surface orthogonal turn-milling processing methods, it is intended to solve existing big straight
Diameter thin-wall part needs to configure special knife bar using orthogonal axial turn-milling cutting method, but for deep hole machining, and the morpheme of cutter is missed
Difference is bigger, the problem of influencing the processing quality of workpiece.
The invention is realized in this way a kind of interior rotary surface orthogonal turn-milling processing method includes：
Step 1: selecting numerically-controlled machine tool, cutting tool choice flat-end cutter or flat-end cutter with rounded corners according to workpiece, formulate
Suitable machining process route；
Step 2: according to cutter location deviation, " additional tool length compensation amount " is attached on tool compensation function, is added
The axis of milling cutter is processed always perpendicular to the inner surface of part during work.
Step 3: using milling cutter end face center point as cutter location, after starting " additional tool length compensation ", by part to be processed
Profile is carried out writing nc program and is processed；
Further, cutter location deviation size and the diameter of workpiece radius and cutter have relationship, flat-end cutter workpieces processing
When datum mark deviation H and workpiece radius R and cutter diameter D between relational expression be：
Further, band fillet r1Flat-end cutter processing cutter location deviation H1With workpiece radius R1With cutter diameter D1
Between relational expression be：
Therefore, the additional length offset general formula on tack face cutter orthogonal turn-milling Inner arc surface is：
The processing method that the present invention uses tack milling, the technology that can give full play to the efficiency of high-rate wireless LAN etc. are excellent
Gesture ensures the production efficiency of thin-wall part machining；
The processing method that flat-end cutter carries out orthogonal turn-milling can meet rotary surface, particularly inner mesh in processing
Surface process requirements；
By adding amendment of the tool length offset to tool length compensation amount so that be programmed by parts profile
Programmed method is still effective.Programming efficiency is improved, reduces influence of the Programming Error to machining accuracy.
