Abstract

A system, method and software arrangement are provided for generating press-formed parts having a more consistent quality based on improved determination of processing conditions. For example, an apparatus can be configured to compare actual performance values of material properties provided by a material property database with standard values, and to adjust forming conditions such as a forming speed and a blank-holder pressure in accordance with the compared result. A control arrangement can be provided to control a press-forming device using the adjusted forming conditions. Accordingly, it may be possible to reduce occurrences of defects such as cracks and wrinkles when press-forming materials, and to obtain products having consistent quality and substantially identical shapes.

transmitting at least one first material property stored in a database using the second processing arrangement, wherein the at least one first material property is associated with the at least one identifier;

receiving, at the first processing arrangement, the at least one first material property; and

press-forming the at least one material using a process condition which is based on the at least one first material property,

wherein the at least one identifier includes a production lot number, and

wherein the second processing arrangement includes a first hardware arrangement associated with a manufacturer of the at least one material and the first processing arrangement includes a second hardware arrangement associated with a customer of the manufacturer.

2. The method of claim 1 , further comprising determining the process condition based on the at least one material property using a calculation arrangement.

3. The method of claim 2 , further comprising controlling at least one of a speed of the punch, a speed of the die, a mold temperature, or a blank-holder force based on the at least one process condition using a control arrangement.

4. The method of claim 3 , further comprising determining at least one of the speed of the punch, the speed of the die, the mold temperature, or the blank-holder force based on a first information using the calculation arrangement when the at least one material is press-formed, wherein the first information comprises at least one of a punch reaction force, the mold temperature, a mold distortion, a deformation of the material, or a temperature of the at least one material, and the at least one material property.

5. The method of claim 4 , further comprising measuring the first information using a measurement arrangement, wherein the at least one process condition is determined based on the first information measured by the measuring arrangement and based on the at least one first material property received by the first property receiving arrangement.

6. The method of claim 5 , further comprising determining at least one of the speed of the punch, the speed of the die, the mold temperature, or the blank-holder force such that the first information assumes a value within a tolerance range when the first information measured by the measuring arrangement lies outside of the tolerance range using the calculation arrangement.

7. The method of claim 6 , further comprising:

storing the first information using a storage arrangement, and

determining a moving average value of the first information at least one of within a particular time interval or at a particular number of times based on the first information, and is still further configured to determine at least one of the speed of the punch, the speed of the die, the mold temperature, or the blank-holder force such that the moving average value is within the tolerance range using the calculation arrangement.

8. The method of claim 5 , further comprising:

storing the first information using a storage arrangement, and

comparing a current value of the first information measured by the measuring arrangement with a previous value of the first information stored in the storage arrangement, and is further configured to determine at least one of the speed of the punch, the speed of the die, the mold temperature, or the blank-holder force based on the comparison using the calculation arrangement.

9. The method of claim 2 , further comprising:

receiving at least one second material property that is different from the at least one first material property received by the property receiving arrangement using a second property receiving arrangement, and

determining the at least one process condition based on the at least one second material property and based on the at least one first material property received by the property receiving arrangement using the calculation arrangement.

10. The method of claim 9 , wherein the at least one second material property comprises data obtained before the at least one material is formed by the press-forming apparatus.

11. The method of claim 9 ,

wherein the at least one first material property received by the property receiving arrangement is associated with a production lot which includes the at least one material, and

wherein the at least one second material property provided by the second property receiving arrangement is associated with the at least one material.

12. The method of claim 1 , wherein the at least one first material property comprises at least one of a sheet thickness, a yield stress, a 0.2% proof stress, a tensile strength, an elongation, an n-value, an r-value, a relational expression between a stress and a strain, a hardness, a temperature, a surface roughness, a friction coefficient, or a lubricant film thickness associated with the at least one material.

13. The method of claim 2 , further comprising providing the at least one first material property to the calculation arrangement using a data transfer arrangement, and preventing access to the at least one first material property by a user when the at least one first material property is provided to the first processing arrangement using the data transfer arrangement.

14. The method of claim 1 , further generating a bill based on a transmission of the at least one first material property to the first processing arrangement using a billing arrangement.
