Increase the Rapid Traverse speed by 2%. Set the Rapid Traverse speed to its full value—1/3 of the axis’s rapid traverse speed.

  • Page 49: Incremental Feed

    HNC-18/19T Operator’s Manual Incremental Feed INC feed is used to move an axis a fixed increment of travel. Pressing a key in incremental or INC mode, moves the cutting tool one increment in that axis and direction. When in INC mode, the cutting tool moves at the JOG feedrate (See JOG Feed Functions above for adjusting the JOG feedrate).
  • Page 50 3 MANUAL OPERATION INC mode LED indicator light INC mode key For each press of the feed axis keys: +X, -X, +Y, -Y, +Z or -Z, the tool cutter moves a certain distance. To move the cutting tool toward the workpiece use a minus key (-X, -Y, -Z). For moving the cutting tool away from the workpiece use a plus key (+X, +Y, +Z).
  • Page 51 HNC-18/19T Operator’s Manual The distance is the number of minimum steps times the magnifier value. The four keys below select the step length magnification in the INC mode. Pressing any key changes the magnification of the corresponding distance. As before, the LED light associated with the selection lights up indicating which magnification is chosen.

    HNC-18/19T Operator’s Manual Program Loading A program file must be “loaded” into the mill’s memory before it can be “executed” (i.e., cut a part or do some other operation automatically). The program file itself is a series of program lines called blocks that direct the mill through a series of various operations automatically.
  • Page 64 HNC-18/19T Operator’s Manual Now press the F1 physical key, which correspond to OPEN softkey. F1 OPEN softkey 3) On pressing the OPEN softkey, the LCD screen shows a file directory: a list of program files like the ones below.

  • Page 65: Program Testing

    HNC-18/19T Operator’s Manual Program Testing A program which has just been created or changed should be tested or tested before it is actually used to cut parts. Program verifying can find errors in the program without actually running the machine and possibly damaging the mill or the workpiece.
  • Page 66 4 AUTOMATIC OPERATION Note that there is no motion of the cutter or any other action that takes place. The TEST process is a simulation of the motion or action that would take place.

  • Page 67: Running Control

    HNC-18/19T Operator’s Manual Running Control Once tested successfully, the program can be confirmed by executing automatically with AUTO mode or by stepping through each block of the program in the SBL mode (Single Block mode) This confirmation is important on new or recently modified programs to be sure the cutting tool does not run into fixtures and that the feeds and speeds are properly set.
  • Page 68 4 AUTOMATIC OPERATION Beside these four softkey functions, there are two hard key functions to control the running process. Totally there are eight different operations to control the running process: Cycle Run: cycles through the program Feed Hold: stopping the motion of the program with a softkey press begin the program operation again after a pause Restart:...
  • Page 69 HNC-18/19T Operator’s Manual This function begins program execution. Cycle Run: Requirements: 1) The program has been successfully tested. 2) The machine is in Single Block (SBL) mode or Automatic (AUTO) mode. Sequence: 1) Press the green Cycle Run button and the program will be executed.
  • Page 70 4 AUTOMATIC OPERATION 2) After the Feedhold button is pressed, you can stop all action by pressing the Emergency Stop button. If you just want to exit the program, cancel it with the PAUSE operation below. If the program has been canceled, it can be restarted Restart: from the program beginning by pressing the REW(REWind) softkey.
