Detailed description of the invention:
The experimental technique of test turning steep-pitch thread Tool in Cutting performance of the present invention, comprises the following steps:
One, turning is carried out by test tool double thread test specimen, adopt three having two cutting edges screw thread test specimen identical with three with the test tool of different operating angle, during turning, lathe keep the radial cutting-in of test tool consistent with screw thread test specimen screw thread groove depth, with often the cutting to left and right sword of test tool respectively vertically the left and right flank of the one-sided mode double thread test specimen successively cut repeatedly successively cut, until the surface processing accuracy of screw thread test specimen reaches designing requirement, specifically:
First, design and grind out the threading tool that three are respectively used to turning pitch 16mm, three test tool are all with two, left and right cutting edge, and the cutting edge inclination of two cutting edges is 0 °, often test tool all can be mounted and dismounted on existing cutter hub, three as shown in table 1 to the working rake angle of test tool cutting to left and right sword, working orthogonal clearance and tool cutting edge angle:
Table 1 three is the operating angle of cutter
Above-mentioned three are used for test tool in the fine finishining of the trapezoidal external screw rod of turning pitch 16mm, its geometric angle and geometric parameter can make screw thread test specimen reach the trapezoidal externally threaded physical dimension requirement of pitch 16mm, its cutting to left and right sword can repeatedly successively cut respectively, to ensure that the machined surface quality of left and right flank reaches experimental technique requirement.
Secondly, design and process the trapezoidal external screw thread test specimen of dextrorotation of three diameter 120mm, length 200mm, pitch 16mm, the material of this screw thread test specimen is 35CrMo.
Finally, adopt above-mentioned three test tool on CA6140 lathe, with rotating speed n be 10rpm, allowance a
pffor 0.05mm keeps cutter radial cutting-in consistent with workpiece screw thread groove depth, repeatedly successively cut by the surface of the one-sided mode double thread test specimen successively cut shown in Fig. 1 vertically respectively with test tool cutting to left and right sword, often the left and right flank of cutter successively screw cutting test specimen, until its machined surface roughness value reach less than Ra3.2 μm, full stand of thread central diameter control errors till below 0.036mm, successively cut number of times when reaching this requirement on machining accuracy as shown in table 2:
Table 2 three is the successively cutting number of times of test tool
As can be seen from Table 2, test tool 2 makes left and right flank finished surface reach predetermined crudy requirement with the minimum number of times that successively cuts, and the cutting time used is minimum, apparently higher than test tool 1 and test tool 3 in its stock-removing efficiency.
This result shows, adopt above-mentioned three test tool with identical successively cutting number of times processing left and right flank, the flank of three screw thread test specimens cannot be made to reach identical machined surface quality and requirement on machining accuracy, have to cut number of times made up gap in crudy by increasing, its result must cause stock-removing efficiency to reduce.
Two, three are detected the stock-removing efficiency of test tool, reach less than Ra3.2 μm using the surface roughness value of machining screw test specimen, full stand of thread central diameter control errors often successively cuts number of times sum as the total cutting number of times often test tool the cutting to left and right sword of test tool when below 0.036mm, record the stock-removing efficiency that three determine total cutting number of times of test tool three test tool respectively.
Three, detect three the abrasion width of knife face after about test tool, after cutter knife face whole wearing and tearing length on choose a measurement point at a certain distance, adopt super depth-of-field microscope to check the abrasion width of each measurement point.In this process, in the fine finishining of turning steep-pitch thread, cutter has three cutting edges to participate in cutting, be respectively left cutting edge, tooth top sword and right cutting edge, during owing to cutting at every turn, allowance is 0.05mm vertically, tooth top sharpening damages the formation of left and right flank and affects without conspicuousness cutter life, and therefore, the cutting to left and right sword wear of the tool flank length of three test tool is chosen in experiment and abrasion width is measurement parameter.Wherein, in table 1, the left cutting edge wear of the tool flank length of test tool 3 and abrasion width are as shown in Figure 2 and Figure 3, super depth-of-field microscope is adopted to amplify 150 times when carrying out test tool wear measurement, clearly can identify cutter wear of the tool flank border, but because multiplication factor is too high, cannot one-shot measurement whole piece Tool in Cutting sword, therefore be divided into 5 regions to carry out abrasion width measurement along test tool wear of the tool flank length direction, be spaced apart 0.8mm between each measurement point.Wherein, in table 1, the left cutting edge wear of the tool flank width data extraction step of test tool 3 is as shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, three test tool left and right wear of the tool flank width measurements contrasts as shown in Figure 9, Figure 10, from Fig. 9, Figure 10, contrast three is left back for test tool knife face abrasion width, the abrasion width of test tool 1 is maximum, and test tool 3 is taken second place, and test tool 2 is minimum; Contrast three is right back for test tool knife face abrasion width, the abrasion width of test tool 3 is maximum, and test tool 1 is taken second place, and test tool 2 is minimum, find, the left back knife face abrasion width of test tool 1 presents obvious inhomogeneities along distribution on cutting edge length direction simultaneously.
The left wear of the tool flank of contrast test cutter 1 and test tool 2, the impact of tested person cutter left cutting edge different operating relief angle, they are obviously different at identical cutting times condition bottom left wear of the tool flank width; The right wear of the tool flank of contrast test cutter 1 and test tool 3, the impact of tested person cutter right cutting edge different operating relief angle and tool cutting edge angle, although the cutting number of times of test tool 1 comparatively test tool 3 cuts often 54.5%, its right back knife face abrasion width is significantly less than test tool 3.This result shows, by the impact of different operating relief angle and tool cutting edge angle, adopt above-mentioned three test tool is cut steep-pitch thread, when reaching identical machined surface quality and requirement on machining accuracy, there is notable difference in cutter, the cutting ability making it to process the long screw thread of coarse pitch is obviously different on wear of the tool flank width.
Each test tool left and right wear of the tool flank width versus is as shown in Figure 11, Figure 12, Figure 13, from Figure 11, Figure 12, Figure 13, there is significant difference in the left and right wear of the tool flank width of test tool 1 and distribution thereof, left and right wear of the tool flank width and the distribution thereof of test tool 2, test tool 3 are then comparatively close.This result shows, in turning steep-pitch thread process, by operating angle and the cutting number of times of adjustment cutter cutting to left and right sword, cutter left and right wear of the tool flank width and distribution thereof can be made to be close, improve cutter whole service life and stock-removing efficiency, to meet the technological requirement that steep-pitch thread Long travel cuts.
Four, with the total cutting number of times often cutter, cutter left and right wear of the tool flank width and difference thereof for Tool in Cutting Performance Evaluating Indexes, in three test tool, select the cutter of applicable turning steep-pitch thread, specifically;
According to above-mentioned experimental result, less than Ra3.2 μm is reached with flank machined surface roughness value, full stand of thread central diameter control errors is constraints at below 0.036mm, with the cutting total degree often cutter, cutter cutting to left and right sword wear of the tool flank width and difference size thereof are Tool in Cutting Performance Evaluating Indexes, total cutting least number of times of visible test tool 2, the cutting to left and right sword wear of the tool flank width of test tool 2 is minimum, and the difference of its cutting to left and right sword wear of the tool flank width is also minimum, therefore the cutting ability of test tool 2 is best, thus determine for the trapezoidal externally threaded process program of turning pitch 16mm dextrorotation and be:
The cutting edge inclination of cutter cutting to left and right sword be 0 °, working rake angle 2 ° of 36' of the left cutting edge of cutter, working orthogonal clearance 6 ° of 18', tool cutting edge angle 73 ° of 26', the right cutting edge working rake angle of cutter-2 ° of 36', working orthogonal clearance 9 ° of 04', tool cutting edge angle 102 ° of 46', keep cutter radial cutting-in consistent with workpiece screw thread groove depth, with rotating speed 10rpm, one-sided successively machining surplus 0.05mm, the left cutting edge of cutter one-sided successively cutting 14 times, right cutting edge one-sided successively cutting vertically vertically 5 times.
