Description
Technical field
The invention belongs to field of machining, more particularly, to a kind of tool paths generation algorithm.
Background technique
Carrying out processing by cutter in numerical control processing is the most common processing method, the speed and precision of tool sharpening
Directly influence production efficiency.Since current all CNC automatic programming softwares are all without tool sharpening path optimization module, because
This numerical control programming personnel are the empirically determined processing sequences by oneself, therefore machining path is difficult to realize to the reasonable of path
Optimization, this is by extreme influence production efficiency.Therefore, researching and developing a kind of tool paths generation algorithm is a urgent problem to be solved.
Summary of the invention
In view of this, the present invention is directed to propose a kind of tool paths generation algorithm, can carry out cutter path rationally excellent
Change.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of tool paths generation algorithm, process are as follows:
1, according to the planning problem in tool sharpening path, cutter mathematical model is established in analysis；
2, practical tool sharpening route is extracted, according to close cutter mathematical model；
3, the actual path of reference tool processing, changes the relevant parameter of mathematical model；
4, cutter mathematical model is calculated and it is solved, to obtain the optimal machining path of tool sharpening.
Further, in step 2, it when extracting practical tool sharpening route, is completed: being obtained actual using following steps
Cutter location is segmented according to mathematical model to cutter location and is determined the connection type type and each segmentation of each segmentation
Between boundary point, the cutter location of curved section is extracted according to mathematical model according to the type of these boundary points and connection type.
Further, the cutter mathematical model becomes according to the diameter of selected cutter, length, thickness and adjusting parameter
Amount.
Further, estimation error is carried out after calculating cutter mathematical model and solving to it, and passes through error
Correction model is modified.
Further, in second step, multiple cutter mathematical models being close can be selected to carry out subsequent processing, chosen
Optimal cutter mathematical model.
Further, error correction model is DHSY model.
Compared with the existing technology, tool paths generation algorithm of the present invention has the advantage that this cutter path is raw
It is modeled at algorithm using mathematical model, is compared by practical tool position with mathematical model, chooses optimal processing road
Diameter can effectively improve processing efficiency, convenient for operating, be widely used.
Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
Below with reference to embodiment, the present invention will be described in detail.
A kind of tool paths generation algorithm, process are as follows:
1, according to the planning problem in tool sharpening path, cutter mathematical model is established in analysis.
2, practical tool sharpening route is extracted, according to close cutter mathematical model.
Extract practical tool sharpening route when, completed using following steps: obtaining actual cutter location, to cutter location according to
Mathematical model is segmented and is determined the boundary point between the connection type type and each segmentation of each segmentation, according to this
The type of a little boundary points and connection type extracts the cutter location of curved section according to mathematical model.
Multiple cutter mathematical models being close can be selected to carry out subsequent processing, choose optimal cutter mathematical model.
3, the actual path of reference tool processing, changes the relevant parameter of mathematical model.
The cutter mathematical model according to the diameter of selected cutter, length, thickness and adjusting parameter variable 4, to cutter
Mathematical model is calculated and is solved to it, carries out estimation error after calculating cutter mathematical model and solving to it,
And be modified by error correction model, error correction model is DHSY model, to obtain the optimal processing of tool sharpening
Path.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
