The ball screw used on the OmniTurn moves the slide .2” / revolution. So if we position the slide within .2” of what we want to call HOME and then tell the control to slowly rotate the screw while looking for the single pulse we can establish this as an easily repeat- able location.
  • Page 13 The method for moving the slide is to use the ”Joy stick” actuator on the operators panel.

  • Page 18 Hard Disk Features Backing Up Programs OmniTurn CNC Controls are shipped with a solid-state hard drive (C:) for system and programs, and one 3.5 floppy drive, (A:) for part program backup. The user is given an opportunity to backup his program files when machine is booted up. There is no convenient, automatic way to backup before shutting down, so we back-up at turn-on instead.
  • Page 19 The OmniTurn allows true “background editing” because programs copied to the Users Disk may be edited at a desk-top computer while the program is running on the OmniTurn. The newly edited program can be copied back to the hard drive from the Auto Mode screen with almost no interruption in the machining process.

  • Page 29 Tool call statements The “tool call statement” is done in two lines: XnZn The T command must have a tool number in the range of I through 32. When this command is executed the slide will not move. The display showing the absolute location will change to show the distance the tool being used is from the absolute zero of the part.
  • Page 30 Linear moves X n Z n XnZn Linear one and two axis moves are accomplished by giving the axis and the value to move. The result of a command will depend on which mode is active: G90 or G91, and G73 (radius) or G72 (diameter). X moves default to RADIUS mode (G73), not diameters.
  • Page 31 Linear moves X n Z n XnZn A note about feedrate modes: The feedrate commands are modal. Once they are set they stay in effect until they are changed. So once you set the mode you do not have to change it again until you change the mode. Once the feedrate mode is selected you can change the feedrate by adding the new feedrate to the line of code where you need it.
  • Page 32 Linear moves X n Z n XnZn Using G00 for rapid travels The rapid travel mode can be established by using the G00 command. This will set the mode to IPM at a feedrate specified in the first line of the program. If you do not set the feedrate in the first line of the pro- gram it will use the last rapid move it did in either the manual mode (100”/min) or from the last program that was run.
  • Page 33 Linear moves X n Z n XnZn In the example below we will be finish turning a sample part with a left hand tool. The part dimensions are given in diameters.

There are two types of spindle speed control modes that the OmniTurn control can use: Spindle speed in RPM -(G97). In this mode the S value will set the spindle speed in turns per minute, ”RPM”.
  • Page 81 Program commands - “M-Codes” ”M” codes are commands that control operations other than slide movements. These commands are Model. That is, once turned on they stay active until turned off. Some M codes control optional attachments that have to be wired into your lathe. The wiring schematics and example uses are included in the ”Options Documentation”...
  • Page 82 Spindle on, reverse (top going) Spindle off OmniTurn with no spindle encoder: The M03 and M04 will stop the program and instruct the operator ”WAITING FOR SPINDLE”. If the control has an encoder for threading it will know that the spindle is turning.
  • Page 83 These M-codes stop the program until an input ins “on” or “off”. This is useful for coordinating activity for an auto-loader primarily. The OmniTurn ‘waits’ (the program stops, like M00 or M01) until the input is in the correct state.
  • Page 84 Spindle Control Option Cycle Start The cycle start PB on the face of the OmniTurn control is deactivated when a spindle drive control is installed.

  • Page 85 Spindle off automatically at the end of the program: M30 Spindle off by command in the program: Manual override: There is a switch on the face of the OmniTurn control that will turn the spindle off. Leaving the spindle on at the end of the program: If you are running a job automatically (bar work or automatic loaders) and want to leave the spindle running at the end of the program use M02 for end of program.
  • Page 86 Spindle Control Option continued Setting the spindle speed range (for attachments only, GT-75 is done by the factory): With the spindle drive it is possible to setup different maximum speeds to make available more HP at lower spindle speeds. The inverter drives that we use to vary the speed are constant torque at all RPMs. However the HP is lower at the lower RPMs.
  • Page 87 Secondary Offsets What are secondary offsets? Secondary offsets are corrections that you can put into your program that the operator can adjust when running the program without having to go into the program to edit it. Once the program has been written with the secondary offsets incorporated, these corrections are made by pressing F9 while in the Automatic mode and inputting the amounts.
  • Page 88 Secondary Offsets Using Secondary Offsets Secondary offsets are used with D commands. The format is the same as a T command.
