Description
PROCESS OF MODELING
Referent Field of Technic
The invention belongs to the general field of computer designing i.e modeling and drawing of technical objects and other graphs and geometry description on NC/CNC processing machines.
Technical problems
This procedure was purposed to achieve both simple and straight form modeling of technical objects and other graphs or paths (geometry) with NC/CNC... processing machines, to enable a multi-way modeling as simple as possible, without strict rules.
At the same time, there was a wish to model as many forms as possible as well as to apply the same procedure in modeling of forms, including exact dimensions (constants), general dimensions (variables) and the combination of exact and general dimensions. The idea was to create a user-friendly modeling form.
It was not presented the best possible solution for modeling procedure that offers a multi-solution entities following a certain phase of completed modeling procedure.
Present technical solutions
When describing a form to be drawn or modeled, widely used CAD package at AutoCAD market applies a rigid modeling procedures. For example, modeling procedures are rather fixed when drawing a order of coordinates points as well as of some other parameters.
They cannot be applied separately in the description of coordinate of characteristic points but just within the definition of characteristic points. It is not possible to use simultaneously characteristic points in modeling, separate coordinate points and some other parameters in combination with relation statements included within patent claims. It is quite different modeling with general dimensions
(variables) or with the combination of general and concrete dimensions(constants) comparing to the drawing with exact dimensions.
The same principles are not applied in all entities modeling. When modeling a certain entity, it is not possible to call (to refer) to all characteristics that either real or imaginary entity possesses.
In the course of modeling, there cannot be applied all characteristics that define completely that entity.
There is low selection of possible variables purposed for modeling- modeling diversity is limited. When applying the modeling procedure (drawing) there appear just a few modes of modeling possibilities (drawing) for entities ( straight line, arc, circle) since it was not applied a proper solution of the selection of necessary set of points for desired entity out of two or more sets of points. The possibilities of industrial and some other applications of the invention:
The invention can be applied in designing, modeling (construction, drawing) of technical objects as well as with modeling/ drawing of some other graphs. The further possibility is to apply it in geometry programming, making parts on NC/CNC... machines for metal processing, wood processing etc.
Acquainting with the essentials of the invention
In modeling procedure when applied initial geometric data, such as characteristic points or coordinates of characteristic points, parallelly , right-angled and tangently relations and geometric parameters such as length, angle, radius, diameter etc. cannot offer only one solution, we introduce relation statements into the further course of the procedure. Relation statements present the relation among the position of entities' points, applying points coordinates and some other characteristic geometric parameters within a relation statement. These are relation statements that either include the relation greater (than) or the relation less (than) or the relation that, at least, contain the relation greater (than) or relation less (than), such as relations greater or equal or less or equal, not greater (than) or not less (than), not greater or equal or not less or equal and in which relation statement, at one side includes, at least, one coordinate of characteristic point such as start point, end point, central point etc. or, at least, one characteristic geometric parameter such as angle, length, diameter, radius etc. out of the modeled entity and that is exactly the coordinate of a characteristic point or a characteristic geometric parameter that offers two solutions on the basis of previously applied procedure or previously described part of the procedure. It is possible to include within the modeling procedure relation statements such as " a bit greater" or " a bit less" or invertly set relation statement such as "greater in some way" or "less in some way" or some other variants of this relation statement such as "something is not greater" or "something is not less" where the relation "not greater" i.e. "not less" or invertly set relation statement such as " something not greater" or " something not less" where just the one side of the relation "greater" (not greater in one variant) or less (not less in one variant) includes at least one coordinate of a characteristic point, such as start point, end point, central point etc. or, at least, one characteristic geometric parameter, such as angle, length, diameter, radius etc, included within the modeled entity; it is the coordinate of the characteristic
point or the characteristic geometry parameter that included two solutions, arising from the previously described procedure or previously described part of the procedure.
This procedure is used to establish the correctness of this relation statement and in the course of further procedure, it is selected the solution that offers the data that satisfy relation statement purposed for the modeled entity ( the data that are included within the relation statement).
Detailed description of the invention
Modeling procedure is intended for elements modeling i.e drawing as well as for the modeling and drawing of some other details and graphs i.e entities, widely applied in the course of designing or modeling of geometry in manufacturing of parts on NC/CNC...machines.
Applying of this modeling procedure enables modeling of a form with general, exact dimensions of an object that is to be modeled.
The terms including a standard mathematical operations such as ( addition, subtraction, multiplication, division, raising to a power), standard mathematical functions (sine, cosine, tangents, logarithm etc), variables, constants, coordinates of characteristic points, sets of coordinate points and some other characteristic parameters such as (diameter, radius, angle, length etc), entities and distance between defined points and coordinate points of an entity section can be applied in defining of any point values ( a set of its coordinates), point coordinates as well as some other characteristic parameters. Apart from that, when inserting the value of a characteristic point it is possible to join to it a value of subset coordinates for a given characteristic point of any other entity.
Applied relation statements ( tangently, right-angled, parallel etc) in the course of modeling procedure help to define the position of the entity that is going to be modeled against some other entity. Apart from that, relation statements present relation among the position of the entity points of the modeled entity (applying point coordinates and some other characteristic geometry parameters within a relation statement). These are relation statements in which the left and the right side of the relation (greater, greater or equal, less, less or equal etc), include terms that, apart from standard mathematical operations, standard mathematical functions, variables, constants etc, could include coordinates and some other characteristic entity parameters. The term, appearing both on the left and the right side of the relation, can be formed in the same way that is used in defining of values of any other geometry characteristic of an entity ( coordinates of characteristic points or some other parameters such as angle, diameter, radius, length etc).
Additionally, it is possible to use a special type of a statement that includes only one term on one side of the relation (greater, less, not greater, not les), while the opposite side does not include anything.
These two types of relation statements are applied with entity modeling, in the case when on the basis of the rest of the primary(geometric) entity description there could be obtained two solutions i.e two sets of points referring to a given entity. In this case, this statement defines (imposes) which of the two sets of points should be selected.
The solution is to include coordinates and some other characteristic parameters within a relation statement. With the special type of a relation statement, the easiest solution is to require the value of a coordinate of some characteristic point or the value of some parameter to be either greater or less ( for example, x coordinate of some characteristic point greater, angle is less, a radius is greater etc). As already explained, in modeling of some other entity, there could be applied i.e call all characteristics of any other defined entity.
This procedure requires to present some characteristic (characteristic point, coordinate of a characteristic point and some other parameters, such as diameter, radius, angle, length etc) or the relation of the position
(tangently, right-angled, parallel etc) as well as to select the entity whereout it was taken the given characteristic.
At this point, it should be emphasized that the modeling procedure is really user-friendly.
When modeling a certain entity, it is possible to attribute a value to any given characteristic applying the same characteristic or taking some other (suitable) characteristic belonging to some other defined entity, that is used in modeling of the said entity.
When taking the value of some other characteristic (characteristic point, coordinate of a characteristic point, angle, length, diameter, radius, function purposed for coordinates derivation- domain and co- domain at a given domain, colore, line type etc..) as well as with relations-based modeling (tangently, right-angled, parallel etc), it must be also defined the entity whereout this characteristic was taken i.e. the entity that is going to be modeled within some relative relation (right-angled, parallel etc). In the case of presenting of some characteristic coordinate or some other characteristic geometry parameter, belonging to the same entity (that is going to be modeled), it can be omitted the entity whereout the said characteristic was taken.
In the course of entity modeling, applied in this invention, there are used relation statements. It is a procedure of entity modeling, when a part of the procedure offers multy-solutions referring to the entity to be modeled (straight line, arc, circle etc) and inclusion of relation statements enables suitable entity modeling.
Rational statements define closely the position of the entity to be defined, either on the basis of the relationship between characteristic coordinates and the parameter of the entity itself to be defined and some other integral parts of the relation statement or on the basis of the position of the given entity in relation to some other, previously defined entity.
With the first type of the relation statement, it is put a request that "something" ( "that very something" is presented on one side of the relation "less" or "greater") shall be "less" or "greater" than something (that is presented on the other side of the relation "less" or "greater").With the other type of a relation statement, it is set a request that something ("that very something" is expressed on one side of the relation
"less" or "greater" than), shall be "greater" or "less".
Types of relation statements
Type no.1:
General definition:
Something less than of something
Something greater than of something
Here is presented the structure of the expression on the left side of the relation "less than" or the relation
"greater than".
The expression for "something" contains at least one of the following geometrical characteristics: x or y coordinate of some characteristic point,
Characteristic parameter of the entity to be modeled or, at least, x or y coordinate of the section point of the entity to be modeled and some other entity.
Here is presented the structure of the expression on the right side of the relation "less than" or the relation "greater than":
Expression for " than something" contains, at least, a constant or either one variable or x or y coordinate of some characteristic point of the entity to be modeled or some other entity or, at least, x or y coordinate of the section point of the entity to be modeled and some other entity or at least a characteristic geometric parameter of the entity to be defined.
Type no.2: General definition:
Something greater
Something less Here is presented the structure of the expression "something":
Expression for "something" includes, at least, one of the following geometric characteristics: x or y coordinate of some characteristic point of the entity to be modeled or, at least, characteristic parameter of the entity to be modeled or, at least, x or y coordinate of the section point of the entity to be modeled and some other entity.
This is the structure for "something" and " than something" with the relation expression of Type no. 1 even when are applied relation expression in combination with some other relations within this type of the relation statement, presented within the section referring to the essentials of the invention. It is similar with Type no.2 relation statement where the relation change does not affect the basic set of this relation statement i.e the relation is used to search for one of the two solutions for "something". Relation statement based modeling procedure of an entity Something less than something or Something greater than something in this case it is as follows:
Include relation statement. If necessary, calculate the arithmetic expression on the left and on the right of the given relation "greater than" or "less than". Compare the values and define whether the value of the relation expression is "true" or "not true".
If the value of the relation statement with the first implementation (command, command line or similar) is "true" , all the values given for coordinates of the characteristic points ( and characteristic parameters), that define the entity, remain the same, but if the value of the relation statement is "not true" then the values of the coordinates of the characteristic points and some other characteristic parameters shall be changed ( it is taken some other data collection, such as points, coordinates of the characteristic points and parameters such as angle of the lengths, diameter, radius) so that the value of the relation statement becomes "true".
In other words, it is applied the solution whose geometric data within some relation statement lead to the truthfulness of the relation statement. By this procedure it is possible to select the set of the points for desired entity on the basis of the set request that asks for the value of the relation statement to be "true".
The same procedure is applied when some other relations are used, within this type of the relation statement, presented within the section referring to the essentials of the invention.
In the course of modeling, here are compared the values appearing on the left and on the right side of the relation.
The procedure of entity modeling by means of relation statements
Something greater or something less in this case is as follows:
Include relation statement. If necessary calculate the arithmetic expression on the left i.e on the right side of the given relation "greater" that is "less", using the data obtained from the both solutions. Compare the obtained values from both solutions and select the solution in which the value of the relation statement is "true". In other words, it is selected the solution whose geometric data within some relation statement lead to the truthfulness of the relation statement. This procedure enables to select the set of the points purposed for the target entity, applying the request that a value of the relation statement is "true". In the course of modeling procedure, here are compared the values obtained from the both solutions purposed for the entity to be modeled.
Hence, the modeling procedure includes relation statements, if necessary it is calculated the arithmetic expression (if it appears within the relation statement), the truthfulness (correctness) of the relation statement is checked. The selection of the solution for the entity to be modeled is made on the basis of the selection of the solution whose data lead to the truthfulness of the relation statement. Modeling procedure at an alternative of straight-line entity modeling
This procedure is purposed to separate set of points for target entity straight line, on the basis of a set request so that the value of relation statement is "true". The procedure of straight-line modeling, on the basis of input data such as characteristic points ( x y coordinates pair), coordinates of characteristic points, lengths parameter and angle parameter in relation to axis coordinates and the relation with some other entities, such as parallel with another straight-line, perpendicular on the other straight line or circumference or arc, tangently on the other circumference or arc in the case when input data offer two solutions for the previously applied procedure or in a previous part of the procedure, can generally be presented such as:
Previous procedure or pre-procedure
The selection or entrance data input, out of the stated collection in a previous chapter, naturally necessary and sufficient to produce two solutions for a straight line (two sets of straight-line points i.e two collections of characteristic points or a coordinate of characteristic points and lengths parameters and the angle in relation to axis coordinates). There can be obtained two solutions of a straight-line (line) on the basis of the calculation of necessary unknown coordinates of characteristic points and possibly the calculation of an angle parameter in relation to axis coordinates and a straight-line.
Modelling procedure:
By applying the relation statement of type 1 (something is greater than something i.e. something is less than something) or the relation statement of type 2 (something is greater i.e. less) input or selected in this operation or prior to this operation, it is possible to examine so that the relation statement is "true", whereby it is separated one collection for a straight-line and its data, included within the relation statement, enabling the relation statement to be a "true" one.
The example of one variant of a straight-line purposed modeling procedure on the basis of previously described procedure
Position the start point (specify the coordinates of this point)
By specifying the length of a straight-line (i) the relation parallel with the straight line (i), or perpendicular on a straight-line (i), arc (i) or circumference (i) or tangently on arc (i) or circumference (i) define the solution for two straight-lines (j) and (j") (calculate the data for two straight-lines (j) and (j") such as angles in relation to a single coordinate axis, coordinates of the end points purposed for two solutions., coordinates of a middle points purposed for two solutions or just a number of these geometrical data so that the straight-lines (/)' and (j") are completely defined. The modeling procedure or additional part of modeling procedure:
On the basis of a specified relation statement of type 1 or type 2, select one of two straight-lines i.e either j' or j" so that the data (such as coordinates of a characteristic points or an angle in relation to coordinate axis-here, in this example, within relation statement of type 1 can include the coordinates of a start point as a geometric characteristics that are same for both straight-lines j' andj", and at least some of the characteristics, such as angle in relation to coordinate axis, one of the coordinates of the end point or a middle point as a geometric characteristics that can be distinguished between straight lines j' and j" included within the relation statement of any type; it is a must to include a geometric characteristic, that is different for straight lines f andj", within a relation statement so that it satisfies the requests arising from relation statement.
One of the ways to examine the truthfulness( correctness) of a relation statement can be done by introducing the data included within a relation statement- firstly for one straight linej' or j" and ifdata( including coordinates of characteristic points or angle in relation to an axis coordinates that differ from these two solutions) these straight-lines, included within a relation statement, leading to a true relation statement are accepted as all necessary data referring to a subject straight-line and in a case when the data (among which are coordinates of characteristic points or an angle in relation to a coordinate axis that differ in these two solutions), then the said straight-lines, included within a relation statement, lead to untrue relation statement and all the other necessary data are accepted for the other straight-line.
