Programming manual 7. ADDITIONAL PREPARATORY FUNCTIONS Scaling factor (G72) CNC 8035 ·T· MODEL (SOFT V16.3X) ·126· 7.6 Scaling factor (G72) By using function G72 you can enlarge or reduce programmed parts. In this way, you can produce families of parts which are similar in shape but of different sizes with a single program. Function G72 should be programmed on its own in a block. There are two formats for programming G72 : Scaling factor applied to all axes. Scaling factor applied to one or more axes.
7.6.1 Scaling factor applied to all axes. The programming format is: G72 S5.5 Following G72 all coordinates programmed are multiplied by the value of the scaling factor defined by S until a new G72 scaling factor definition is read or the definition is cancelled. Example programming the X axis in diameter. The following subroutine defines the basic machining operation. G90 X200 Z0 G01 X200 Z30 F150 G01 X160 Z40 G03 X160 Z60 I0 J10 G02 X160 Z80 I0 J10 G03 X160 Z100 I0 J10 G02 X160 Z120 I0 J10 The programming of the parts would be : Execution of subroutine Machines “A1”. G92 Z0 ; Coordinate preset (zero offset) G72 S0.5 ; Applies a scaling factor of 2 Execution of subroutine Machines “A2”. G72 S1 ; Cancel the scaling factor M30 ; End of program Function G72 is modal and is cancelled when another scaling factor with a value of S1 is programmed, or on power-up, after executing M02, M30 or after EMERGENCY or RESET.
