[. . . ] In this operating mode, when a new constant surface speed is selected, the following cases may arise: a) The spindle is stopped The CNC selects the new speed but does not apply this until the spindle moves. b) The spindle is started The CNC, depending on the position of the axis, calculates and makes the spindle turn at the corresponding rpm. As the axes move, when working at Constant Surface Speed, the following cases may arise: a) The spindle is started The CNC moves the axes to the F programmed. As the X axis is moved, the CNC makes the spindle speed (rpm. ) match to maintain the constant surface speed selected. If the tool tip moves away from the turning axis the spindle revolutions therefore go down, and if it gets nearer, they go up. The CNC limits the spindle revolutions to the maximum speed set «SMAX». b) The spindle is stopped but a spindle speed S is selected The CNC calculates, in millimeters/minute, the feedrate corresponding to the last programmed "S" and moves the axis. For example, if «F 2. 000» and «CSS 500»: F (mm/min) = F (mm/min. ) x S (rev/min) = 2 x 500 = 1000 mm/min The axis moves at a feedrate of 1000 millimeters/minute c) The spindle is stationary and there is no spindle speed S selected. The axes will only move in rapid and only if and the relevant axis key are pressed. Chapter 2 - page 21 MCO-TCO work mode 2. 7 HANDLING ISO CODE Press the ISO key once to access the MDI mode. In MDI mode (pressing once) the CNC shows a window at the bottom of the screen. In this window, it is possible to edit a block and execute it later on. In the ISO mode (pressing twice) a special screen is displayed where it is possible to edit up to 6 program blocks in ISO or in high level language. Example: [ISO] G95 G96 S120 M3 G0 Z100 G1 X30 F0. 1 Once the desired block or blocks have been edited, press screen will show the symbol The upper right-hand side of the From this moment on, the blocks being edited may be simulated, executed or stored as any operation or cycle. It is possible to combine blocks edited in ISO code with standard or User machining cycles to make up part-programs. The chapter on "Storing part-programs" describes how to edit them and operate with them. To store blocks edited in ISO code, press Chapter 2 - page 22 MCO-TCO work mode 3. OPERATING WITH OPERATIONS OR CYCLES The following keys should be used to select the machining Operations or Cycles: The standard version offers 2 positioning cycles. To access these cycles, press and to change the cycle, press The manufacturer may define up to 200 different cycles which will be grouped in 20 groups. The access to the rest of the groups must be set in the PLC program by the manufacturer as described later on. To do this, external devices or free keys (blank keys or keys [O1] through [O14]) may be used. To change levels, within each group, press The OEM cycles accessed with each key are: Cycles Cycles Cycles Cycles Cycles Cycles Cycles Cycles Cycles Cycles Cycles 1 2 3 4 5 6 7 8 9 10 11 21 22 23 24 25 26 27 28 29 30 31 41 42 43 44 45 46 47 48 49 50 51 61 62 63 64 65 66 67 68 69 70 71 81 101 121 141 161 181 82 102 122 142 162 182 83 103 123 143 163 183 84 104 124 144 164 184 85 105 125 145 165 185 86 106 126 146 166 186 87 107 127 147 167 187 88 108 128 148 168 188 89 109 129 149 169 189 90 110 130 150 170 190 91 111 131 151 171 191 Chapter 3 - page 1 MCO-TCO work mode The OEM cycles accessed via PLC by simulating the key whose hex code is indicated below are: $F10C $F10D $F10E $F10F $F110 $F111 $F112 $F113 $F114 Cycles Cycles Cycles Cycles Cycles Cycles Cycles Cycles Cycles 12 13 14 15 16 17 18 19 20 32 33 34 35 36 37 38 39 40 52 53 54 55 56 57 58 59 60 72 73 74 75 76 77 78 79 92 112 132 152 172 192 93 113 133 153 173 193 94 114 134 154 174 194 95 115 135 155 175 195 96 116 136 156 176 196 97 117 137 157 177 197 98 118 138 158 178 198 99 119 139 159 179 199 80 100 120 140 160 180 200 Each OEM cycle has the following elements associated with it: · · · · · The The The The The OEM screen of the same number, created with the WGDRAW application software. configuration file P999xxx routine containing the executable program 9xxx program containing the texts being used by all the screens P999995 program containing the help texts for the cycles P999994 So, cycle 4 has associated with it: screen 004, the configuration file P999004 and the routine 9004. the CNC shows all the screens define by the manufacturer (OEM) with the When pressing WGDRAW application software. · Screens 001 through 200 for the canned cycles.

Resume program execution To resume program execution, press The CNC will reposition the tool, moving it to the point where tool inspection began. The CNC will display a window with the following options for selecting the positioning order of the axes.
