Improper use of the numerical control can cause heavy damage on equipment and/or injuries to people. Modification of machine parameters can cause important material damage or lead to irregular product quality. The rear panel may only be removed by a qualified technician (danger of electrocution). Do not expose the numerical control to excessive humidity so as to avoid any risk of electrocution and any deterioration of the equipment. Make sure the numerical control is disconnected from the mains power before carrying out any cleaning. Do not use liquids based on alcohol or ammoniac. In case of malfunction of the numerical control, call a technician. Do not expose the numerical control to direct sun rays or any other heat source. Do not place the numerical control in the neighbourhood of magnetic equipment such as transformers, motors or devices which generate interference (welding machines, etc.) Replace fan filters at regular intervals so as to avoid overheating. ! ! ! ! ! ! ! ! !

NB: The product counter Q does not function in this mode. conserves the current sequence for execution. THE USER INTERFACE PAGE 15 . This mode is used for adjustments when realizing the first product. Automatic mode Normal mode for product production. Changing directly from "programming" mode automatically forces the first sequence of the program. Semi-automatic mode Allows a machine cycle with the current sequence values without automatic sequence change. The DNC automatically changes sequence after each bend. Changing from "programming " mode to "semiautomatic" mode and then to "automatic" mode. as well as for products with only one bend. Manual mode Authorizes axis movement and auxiliary functions using the keys. This allows to take up again a product in production without having to make "empty" cycles. to search for a sequence .to calculate the unfolded length of the sheet .to search for a tool . or copy (teach) the value of an axis positioned manually in the current sequence.to start a product feasibility calculation .

The height of the punch is the distance between the "point" of the punch and its leg face on the beam.

If the resulting bends differ greatly from the programmed value.THE TOOL REFERENCE The machine has been adjusted according to the following principle: When.

The numerical control calculates the bending depth using: ! the REF Y value. the reference and the values above must be controlled.00. ! the geometrical values of the tools. ! the sheet metal thickness. theoretically.

If it is not possible to move the die to obtain a situation as shown above. The value of the material introduced between the punch and the die must then be subtracted to obtain the reference value REF Y. This value must be identical. in on the flat of the die (be careful with the pressure of the active sequence) and read the value indicated by the POS Y1 and Y2 counters. for both counters and also correspond to the REF Y reference value displayed on the PUNCH / DIE PROGRAMMING page. but different from REF Y If the difference between the counters Y1 and Y2 is within the acceptable tolerance. you must access the PRODUCT PUNCHES / DIES page via the main menu.Y1 and Y2 counters greatly different If the counters are not identical and present a difference superior to what is normally tolerated (the press in this case furnishes an angle which varies from one side to the other of the machine). ANNEXES PAGE 69 . The principle of measure / control is identical to that which is described above. a test must be made with another tool in order to determine if the difference comes from the tool itself (tool badly finished presenting a difference in height along its length) or if the press is badly calibrated. In the latter case. to have a reference modified positively in the product XXX and to have a reference modified negatively for the product YYY. you must determine if the difference comes from the height of the die or that of the punch. To modify the reference in a particular product. It is in some ways a reference modification per product tool. Y1 and Y2 counters identical. It is thus possible in this case for the same tool pair used for two distinct products. and program the new reference in the REF Y field which is accessible by the cursor. you must contact the manufacturer. This modification is stored with the product. choice 7. In this case the tool at fault must be corrected so that the REF Y result is identical to the value of the Y1 Y2 counters. All the sequences having the same tooling will be modified. Modification of the reference for the product The possibility exists to modify the reference for each tool used for the product. but the Y1-Y2 value is greatly different from the REF Y value. During the execution of the retraction. An ascent command frees it immediately for another try. The following cases may occur: a) b) the sheet is not pinched during X backgauge retraction the sheet is bent too much during X backgauge retraction To remedy these problems you must: ! verify the sheet thickness and if necessary correct it ! verify the reference and if necessary correct it ! add a CP correction in parameter 37. the CP is closely linked to the Y reference and the sheet thickness. it is thus easy to control if the sheet is pinched sufficiently or too much. if the reference. but is calculated by the DNC using the REF Y value and the sheet thickness. The CP is used by the DNC cycle to maintain the sheet when an X backgauge retraction is programmed. This point is not programmable.

As we have seen at the beginning of this chapter. the beam stops on the sheet.THE CONTACT POINT (CP) OR PINCH POINT Definition: The contact point is the position of the beam which corresponds to the moment when the point of the punch makes contact with the sheet metal placed in the die. The position is determined by the following calculation: PCT = REF Y + Th (sheet thickness). Simply interrupt the descent command before the end of retraction to prevent the beam from bending the sheet. the tooling dimensions and material thickness are correct you can modify this parameter in order to correct the CP (adjustment of the material clamping) without interfering with the other points. A simple way of verifying the position of the CP is to program a sequence with a very large retraction (approx. For the softwares having the "CP correction" parameter.

Remark: For the result to be coherent. the software calculates different bend for the first. second.
