| Summary: | In the present study, the generation of CNC wire bending code (B-code) is explored and an automatic converter is developed in Excel through some mathematical formulae. The B-code comprises of three parameters which have been determined from the previous work, known as feeding length (L), plane rotation angle (R) and bend-ing angle (A). These parameters control the movement of the designed wire bending machine in this way; (L) tells the feeding mechanism how long the straight wire to be fed, (R) constructs the turning mechanism to rotate in certain degrees before the bending operation starts and (A) determines the degrees of bend, performed by the bending mechanism. The input of the converter is the Cartesian XYZ coordinate of each bend point, obtained from the CAD file. This paper also describes the XYZ extraction process from an IGES file, in addition to the CNC code generation. The practicality of these procedures is demonstrated through an example, starting from the wire design, follows by the XYZ extraction and ends with the B-code generation. Moreover, the graphical simulation of the bending operation by the designed mechanism is also presented. However, the capability of these codes in controlling the wire bending machine in the real bending operation will not be discussed in the present work. |
