Abstract
The present invention relates to machining technology field, more particularly to a kind of processing method of forming cutter contour line, the method drawn using CAD software replaces manual tracing, and CAD software need to meet following condition：A, drawn with circular arc order；B, the SPL error for the circular arc and original contour line drawn need to be less than 0.005mm；C, two adjacent circular arcs must be tangent so that switching is round and smooth.The wide SPL of shaping break bar can fast and efficiently be handled by the method for the present invention, computer automatically processes forming cutter profile SPL according to imposing a condition, so as to substitute artificial tracing.
Description
Technical field
The present invention relates to machining technology field, more particularly to a kind of processing method of forming cutter contour line.
Background technology
Current cutter briquetting roller profile is generally the SPL that 3D entities are transformed, and most of numerically control grinder can not be known
Not, the cutter profile that the numerically control grinder application SPL of recognizable SPL is processed is not smooth, SPL node
Place cutting edge roundness sags and crests occur, so to process meet require contoured knife must just handle well switching it is smooth
SPL.And solve the above problems trace designs to replace SPL manually using circular arc line at this stage, it is well known that it is such
Method inefficiency, circular arc switching is also nontangential and in order to which as far as possible close to contour line, the circular arc quantity of description is too many.
The content of the invention
To solve the above problems, the present invention provides a kind of processing method of forming cutter contour line.
The technical solution adopted in the present invention is：A kind of processing method of forming cutter contour line, is opened using bis- times based on CAD
The part drawing practice that feels like jelly replaces manual tracing, therefore CAD software need to meet following condition：
A, drawn with circular arc order；
B, the SPL error for the circular arc and original contour line drawn need to be less than 0.005mm；
C, two adjacent circular arcs must be tangent so that switching is round and smooth.
More than meeting on the basis of three, in addition, the circular arc for substituting SPL will be most by programmed algorithm number of computations
It is few.The reason for minimum number need to be met be：Because circular arc is excessive, lathe reading data and process velocity can be made slack-off, influence life
Produce efficiency, thus lines can meet require while lines quantity to try one's best and lack.
Beneficial effects of the present invention are：The wide batten of shaping break bar can fast and efficiently be handled by the method for the present invention
Curve, computer automatically processes forming cutter profile SPL according to imposing a condition, so as to substitute artificial tracing.
Embodiment
The present invention is a kind of processing method of forming cutter contour line, and the method drawn using CAD software replaces manual tracing,
Therefore CAD software need to meet following condition：
A, drawn with circular arc order；
B, the SPL error for the circular arc and original contour line drawn need to be less than 0.005mm；
C, two adjacent circular arcs must be tangent so that switching is round and smooth.
For example, existing original 3D SPLs, after being handled by the above method, " 3D SPLs " can be by " a plurality of phase
The circular arc line cut " is constituted, and so allowing for existing numerically control grinder can recognize.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
Claims (1)
