Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
The embodiment provides a tool path generation method for automatically identifying groove features, which identifies the groove features of a part to obtain a corresponding vehicle groove track, so that the operation of manually drawing or selecting the groove features by a user can be reduced, the workload of the user is reduced, and the programming work efficiency is improved.
As shown in fig. 1 and 10, the method for identifying a slot feature in this embodiment specifically includes the following steps:
step S1: acquiring a contour line segment of a target object, and recording coordinate information of each endpoint in the contour line segment;
step S2: generating a corresponding position attribute for each endpoint based on the adjacent position relationship between the endpoints, and correcting the position attribute to obtain the open slot characteristic of the contour line segment;
step S3: and sealing the open groove characteristics to obtain closed groove characteristics, and generating a corresponding turning groove track according to the closed groove characteristics to cut the target object.
As shown in fig. 2, the object of the present embodiment is a revolving body component, and the revolving body component is cut by the rotation of a tool on a lathe; therefore, when obtaining the contour line segment of the object, it is only necessary to obtain the outer contour line of any side of the object divided along the axis, that is, the outer contour of the upper half section above the axis of the revolving body part or the outer contour of the lower half section below the axis (as shown in fig. 3); wherein the contour line segment is obtained by means of user input.
Referring to the flowchart of fig. 10, in this embodiment, the parts shown in fig. 2 are taken as examples to illustrate slot feature identification, which is specifically as follows:
as shown in fig. 4, the contour line segment of the target object is subjected to discrete processing to obtain a plurality of discrete points, and the discrete point located at the inflection point of the contour outline of the part is marked as an endpoint PiAnd recording coordinate information [ z, x ] of each endpoint]Wherein z is axial and x is radial.
In this embodiment, each endpoint includes its corresponding location attribute, where the location attribute includes a left-side attribute and a right-side attribute, the left-side attribute represents an attribute status of another endpoint on the left side of the endpoint and adjacent to the endpoint, and the right-side attribute represents an attribute status of another endpoint on the right side of the endpoint and adjacent to the endpoint. According to the coordinate information of each endpoint and the endpoints on the left side and the right side of each endpoint, corresponding attribute information is given to the left attribute and the right attribute of each endpoint; the attribute information comprises peak attribute, valley attribute, station attribute and null attribute, wherein the symbol corresponding to the peak attribute is ^'; the sign "+" corresponding to the valley attribute; the symbol corresponding to the table attribute is "-"; the symbol corresponding to the null attribute is "0".
For example, if an endpoint is PiThen P isiLeft end point of (1) is Pi-1，PiRight end point of (A) is Pi+1；
Comparing the x value of each endpoint with the x value of the adjacent endpoint, wherein the comparison is as follows:
when P is presenti-1<Pi>Pi+1Record PiThe left attribute of (a) is ^, the right attribute is ^, record is
；
When P is presenti-1<Pi = Pi+1Record PiIs ^ on the left side attribute, is-on the right side attribute, is recorded as
；
When P is presenti-1<Pi<Pi+1Record PiIs ^ and the right attribute is ^ and record as
；
When P is presenti-1 = Pi>Pi+1Record PiIs-right attribute ^ and is recorded as
；
When P is presenti-1 = Pi = Pi+1Record PiIs-the right attribute is-recorded as
；
When P is presenti-1= Pi<Pi+1Record PiLeft attribute of-right attribute of, record as
；
When P is presenti-1>Pi>Pi+1Record PiLeft attribute of ^ x, right attribute of ^ x, record
；
When P is presenti-1>Pi =Pi+1Record PiLeft attribute of (c), right attribute of (d), record as
；
When P is presenti-1>Pi>Pi+1Record PiThe left attribute of (2) is x, the right attribute is x, and the record is;
and the extreme points of the leftmost and rightmost sides of the contour line segment are recorded as null, i.e. without adjacent point comparison
。
Meanwhile, the end points where the left-side attribute and the right-side attribute are both peaks are marked as peak points, and the end points where the left-side attribute and the right-side attribute are both valleys are marked as valley points.
After the position attribute of each endpoint is determined, the position attribute of each endpoint can be corrected to obtain the open slot characteristic of the contour line segment; the correction content mainly comprises two parts, namely attribute replacement of a null attribute endpoint and attribute replacement of a platform attribute endpoint.
As shown in fig. 5, since the leftmost end point and the rightmost end point of the outline segment contain null attributes, the attribute replacement of the null attribute end point is mainly performed on the end points on both sides of the outline segment, specifically:
judging the attributes of all the endpoints, judging whether the position attribute of each endpoint contains a null attribute, and finding a first target endpoint containing the null attribute, namely a leftmost endpoint and a rightmost endpoint of the contour line segment; and replacing the empty attribute of the first target endpoint with the left attribute/right attribute which is not in the empty attribute in the first target endpoint. For example, if the left attribute of the first target endpoint is a null attribute and the right attribute of the first target endpoint is not a null attribute, the left attribute of the first target endpoint is replaced with the right attribute of the first target endpoint, so that neither the left attribute nor the right attribute of the first target endpoint is a null attribute.
In this embodiment, if the leftmost or rightmost end point of the contour line segment belongs to the table attribute, it is described that the start/end point of the part is flat, and at this time, another process is usually used for processing, which is not suitable for groove processing in this embodiment, and therefore, the start/end point including the table attribute needs to be processed; in addition, the end point between the starting point and the end point of the contour line segment is subjected to table attribute processing, and the purpose is to distinguish whether the middle table attribute needs to be processed or not, the horizontal line table attribute is converted into the attribute of all peaks, the highest part of the line segment does not need to be processed, and the table attribute below the peak point still needs to be processed. The method specifically comprises the following steps:
as shown in fig. 6, it is determined whether the position attribute of each endpoint includes a station attribute, and if a second target endpoint including the station attribute exists, an adjacent endpoint on a side where the station attribute of the second target endpoint is located is identified, and the station attribute of the second target endpoint is replaced with the left-side attribute/the right-side attribute that does not belong to the station attribute in the adjacent endpoint. For example, if the left attribute of the second target endpoint is a station attribute, the endpoint located on the left side of the second target endpoint is marked as an adjacent endpoint, and the right attribute of the adjacent endpoint is also necessarily a station attribute, so that the left attribute of the second target endpoint is replaced by the left attribute of the adjacent endpoint which is not a station attribute, so that the left attribute of the second target endpoint is no longer a station attribute. Similarly, the points marked as neighboring end points also undergo the above-described table attribute replacement operation until all end points in the contour segment no longer contain table attributes. If the left attribute and the right attribute of any end point are both table attributes, the point is a point on the horizontal line, the point is filtered, the attribute replacement of the next attribute is continued, and finally the filtered end points are processed again until all the end points do not contain table attributes any more.
In this embodiment, after the end points including the null attribute and the end points including the table attribute are subjected to attribute replacement, the peak point and the valley point in the contour line segment are re-determined according to the position attribute of each end point, that is, a point where the left-side attribute and the right-side attribute are both peaks is marked as a peak point, and a point where the left-side attribute and the right-side attribute are both valleys is marked as a valley point. Then, as shown in fig. 7, searching starts from the valley point to both sides, and the searching is finished when the nearest peak point is found or the end of the line segment is found; judging whether two peak points can be found, if so, ending the current valley point search and recording the valley points and the peak points encountered in the search process to form an open groove feature (a thickened line segment in the figure 7 is the open groove feature); and if the two peak points cannot be found, recording that no groove features exist at the current valley point.
In this embodiment, after the open trench feature is obtained, the peak attribute of the open trench feature needs to be determined, and the open grass feature is processed according to the peak attribute to obtain the closed trench feature. The judgment of the peak point attribute specifically comprises the following steps:
judging whether the heights of the peak points of the open groove features are the same, namely judging whether the x values of the peak points are the same, and if the two peak points are the same at the same axial horizontal height, namely the x values are the same, marking the two peak points at the same horizontal height as equal peak points; when the two peak points of the open groove feature are at the same horizontal height in the axial direction, namely two equal peak points exist, the two equal peak points are connected by an auxiliary line to obtain a closed area as the closed groove feature.
As shown in fig. 8, if two peaks of the open groove feature are not at the same level, the peak having a relatively large longitudinal height (large x value) is defined as a first kind of peak, and the peak having a relatively small longitudinal height (small x value) is defined as a second kind of peak; an auxiliary axial line is axially generated by taking the first type peak point with relatively large longitudinal height as an original point, and the auxiliary axial line is generated towards the direction close to the second type peak point; and radially generating an auxiliary radial line by taking the second type of peak point with relatively small longitudinal height as an origin, wherein the auxiliary radial line extends towards the direction of the auxiliary axial line; so that the auxiliary axial line and the auxiliary radial line can enclose a closed area as a closed groove feature, and both the closed areas are the closed groove feature as shown in fig. 8.
The groove features can obtain a plurality of adjacent closed groove features after the closing treatment, whether second peak points with the same longitudinal height exist in the adjacent closed groove features or not is judged, if not, the merging treatment is not needed, and as shown in fig. 8, the second peak points with the same longitudinal height do not exist, the merging treatment is not needed; if the peaks of the adjacent closed slot features are the second type of peaks with the same longitudinal height, as shown in fig. 9, fig. 9 is the closed slot feature obtained according to the slot feature identification method according to the contour line segment of another part, the second type of peaks with the same longitudinal height exist in the closed slot feature of fig. 9 (the black solid end points in fig. 9 are the second type of peaks with the same longitudinal height), at this time, the second type of peaks are deleted, an auxiliary line is made for two first type of peaks in the adjacent closed slot features, the adjacent closed slot features are recombined into a new closed slot feature, at this time, a corresponding turning slot track can be generated according to the new closed slot feature, and the cutter is made according to the turning slot track to achieve the effect of processing the slot.
