DEFINITION OF TERMS

  • 5-axis CNC (Computerized Numerical Control) Machine The automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually via hand wheels or levers
  • Machine coordinate system A point of reference in this system of coordinates is known as machine zero-point
  • Work piece coordinate system A system of coordinates taking this point as reference is called the work piece coordinates system
  • Machine Zero The position located at the farthest possible distance in a positive direction along the X-, Y-, and Z-axes. This position is permanently set for each particular CNC machine
  • Micrometer A hand-held measuring device used to inspect the dimensions of parts. Thy typical micrometer is accurate within 0.001 in. or 0.02 mm
  • Mode A machine state that determines the way it executes manual and automatic commands
  • Optional Stop A code that pauses the program if the appropriate switch is selected on the machine. Optional Stop allows the operator to inspect the machine between operations
  • Override A control that adjusts a programmed speed or feed rate by a certain percentage during operation
  • Part Program A series of numerical instructions used by a CNC machine to perform the necessary sequence of operations to machine a specific work piece
  • Part Programmer The person responsible for the creation of a part program. The part programmer translates the work piece design into program instructions for the CNC machine
  • Proving Out Running a program one block at a time in order to check for accuracy and proper tool set-up
  • Cycle Start The control used to begin a program or continue a program that has been previously stopped
  • Cycle Stop The control used to pause a program. Cycle Stop pauses tool feed but does not stop spindle movement
  • Dry Running Performing a trial run of the part program without any parts or cutting fluids to check the program
  • Edit Mode The mode that allows an operator an operator to make changes to a part program and store those changes
  • Emergency Stop The control that automatically shuts down all machine functions
  • Feed rate Override An override that allows the operator to adjust the feed rate of the tool during operation. The override functions as a percentage of the programmed value
  • Handle Mode The mode that allows for the manual operation of tool movement via the hand wheel. Some machines may have a combined handle/jog mode
  • Rapid Feed Rate Override An override that allows the operator to reduce the rate of rapid tool movement during operation. A rapid override may be 25% of the original rate or less
  • Rapid Mode The mode that allows for the manual movement of machine components at high rates of travel
  • Tolerance The unwanted but acceptable deviation from a desired dimension
  • Tool Offset A stored value that compensates for variations in tool length. Each tool requires an offset, which is measured from the turret or spindle position
  • Zero return The control that automatically locates the turret or spindle in the machine zero position
