Programming manual 9. CANNED CYCLES G66. Pattern repeat cycle canned cycle CNC 8035 ·T· MODEL (SOFT V16.3X) ·158· The profile and the tool After analyzing the programmed profile and depending on the tool used, it will execute that profile or the one closest to it if the one programmed cannot be executed. When the programmed profile (valleys) cannot be executed with the selected tool, a message will be displayed at the beginning of the execution of the cycle. The operator will have the choice to stop the execution and select the right tool. If he doesn't do that, the CNC calculates a new profile in the areas that cannot be accessed by the selected tool and it machines as much as possible. The message is shown during the whole machining operation.
9.1.2 Profile programming syntax When defining the profile, there is no need to program the starting point because it is specified by the cycle defining parameters X and Z. When defining 2 profiles, first define the final profile and then that of the original stock. The first and last profile defining blocks (where the profile or profiles end) must have the block label number. These label numbers will indicate the beginning and end of the profile geometry definition. The profile programming syntax must follow these rules: It may be programmed in absolute or incremental coordinates and may be made up of simple geometrical elements such as straight lines, arcs, rounded corners, chamfered corners, etc. following the syntax rules defined for this purpose. G00 indicates the end of the definition of the final profile and that in this block contains the beginning of the definition of the profile of the original stock. Program G01, G02 or G03 in the next block, because G00 is modal, thus preventing the CNC from issuing the corresponding error message. The profile description must not contain mirror images, scaling factor changes, pattern rotation or zero offsets. It must not contain high level blocks such as jumps, calls to subroutines or parametric programming. It must not contain other canned cycles. The following functions may be used to define the profile: G01 Linear interpolation. G02 Clockwise circular interpolation. G03 Counter-clockwise circular interpolation. G06 Circle center in absolute coordinates. G08 Arc tangent to previous path. G09 Arc defined by three points. G36 Corner rounding, radius blend. G39 Chamfer. G53 Programming with respect to machine zero. G70 Programming in inches. G71 Programming in millimeters. G90 Absolute programming. G91 Incremental programming. G93 Polar origin preset. The following functions may be programmed, although the cycle will ignore them. G05 Round corner. G07 Square corner. G50 Controlled round corner. F S T D or M functions.
