Abstract
The invention belongs to the mechanical manufacturing technology and relates to an improvement of a numerical control cutting method. When a cutting process is carried out by a numerical control machine tool, a cutter and the choice of radial feeding amount are the same as the existing cutting method; the numerical control cutting method is characterized in that: last figures of the rotating speed S of each cutter and the radial feeding amount F are changed. After a part is processed by the cutting method in the invention, the surface roughness of the part is good, cutter shaking is not easy to occur during the machining process and the loss of the cutter is small.
Description
Technical field
The invention belongs to Machining Technology, relate to improvement the numerical control cutting working method.
Background technology
In the process of all kinds of big-and-middle-sized spare parts; When the utilization conventional process tools adds man-hour; Because the restriction of equipment; Can only adopt the relatively-stationary rotating speed and the amount of feeding to process, rotating speed S generally selects according to 10 rev/mins multiple, and axial feeding F selects according to the multiple of 0.05 millimeter/commentaries on classics.Under the prerequisite that Numeric Control Technology is tending towards popularizing in modern times, traditional experience and fixing pattern have still been continued to use in the selection of cutting parameter.Its shortcoming is: the surface roughness of processing back part is bad, and shake cutter phenomenon takes place in the process easily, and the cutter loss is big.
Summary of the invention
The objective of the invention is: propose to be not easy to shake cutter phenomenon, the little numerical control variable parameter cutting method of cutter loss in a kind of good, process of surface roughness of processing the back part.
Technical scheme of the present invention is: numerical control variable parameter cutting method, and use Digit Control Machine Tool to carry out cut, it is characterized in that with the last figure change of each swivel speed S and axial feeding F, concrete steps are:
1, carries out the first cutter cut; The rotating speed S of first cutter and axial feeding F confirm according to following method: rotating speed S selects according to 10 rev/mins multiple, and axial feeding F selects according to the multiple of 0.05 millimeter/commentaries on classics;
2, carry out the second cutter cut; The rotating speed S of second cutter and axial feeding F confirm according to following method: the unit numbers of rotating speed S select 1,2,3,4,6,7,8,9 one of them, the numeral before the individual position is identical with first cutter; The percentile word select of axial feeding F select 1,2,3,4,6,7,8,9 one of them, the numeral before the hundredths is identical with first cutter;
3, carry out Tri-cutter cutting processing; The rotating speed S of the 3rd cutter and axial feeding F confirm according to following method: the unit numbers of rotating speed S select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, individual position numeral before be identical with a last cutter; The percentile word select of axial feeding F select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, the numeral before the hundredths be identical with a last cutter;
4, carry out the four blade cut; The rotating speed S of four blade and axial feeding F confirm according to following method: the unit numbers of rotating speed S select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, individual position numeral before be identical with a last cutter; The percentile word select of axial feeding F select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, the numeral before the hundredths be identical with a last cutter;
5, and the like, till accomplishing cut.
Advantage of the present invention is: the surface roughness of processing back part is good, is not easy to take place shake cutter phenomenon in the process, and the cutter loss is little.Shake cutter phenomenon has been avoided in evidence, the inventive method basically, and cutter life has improved more than the twice.
The specific embodiment
Explain further details in the face of the present invention down.Numerical control variable parameter cutting method uses Digit Control Machine Tool to carry out cut, and the selection of cutter and radial feeds is identical with existing cutting process, it is characterized in that, with the last figure change of each swivel speed S and axial feeding F, concrete steps are:
1, carries out the first cutter cut; The rotating speed S of first cutter and axial feeding F confirm according to following method: rotating speed S selects according to 10 rev/mins multiple, and axial feeding F selects according to the multiple of 0.05 millimeter/commentaries on classics;
2, carry out the second cutter cut; The rotating speed S of second cutter and axial feeding F confirm according to following method: the unit numbers of rotating speed S select 1,2,3,4,6,7,8,9 one of them, the numeral before the individual position is identical with first cutter; The percentile word select of axial feeding F select 1,2,3,4,6,7,8,9 one of them, the numeral before the hundredths is identical with first cutter;
3, carry out Tri-cutter cutting processing; The rotating speed S of the 3rd cutter and axial feeding F confirm according to following method: the unit numbers of rotating speed S select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, individual position numeral before be identical with a last cutter; The percentile word select of axial feeding F select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, the numeral before the hundredths be identical with a last cutter;
4, carry out the four blade cut; The rotating speed S of four blade and axial feeding F confirm according to following method: the unit numbers of rotating speed S select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, individual position numeral before be identical with a last cutter; The percentile word select of axial feeding F select 0～9 one of them, and should numeral different with the selected numeral of a last cutter, the numeral before the hundredths be identical with a last cutter;
5, and the like, till accomplishing cut.
Operation principle of the present invention is: in digital control processing; Adopt numerical control variable parameter cutting method to process, prevented the knife mark after adjacent two cuttves are processed, the coincidence of track, crest, trough that first cutter produces; In the processing of second cutter, will become trough, crest under the perfect condition.The second cutter cutting point will improve the surface roughness of part greatly on the crest of first cutter, simultaneously because the track route of two cuttves does not overlap, help avoiding the vibrations of part and cutter in the process.
