Machining Fundamentals.
26 2 Machini ng Fundamentals 2.1 F undamentals of P o sitioning 2.1 F undamentals of P o sitioning Position encoders and reference marks The machine axes are equipped with position encod ers that register the positions of the machine table or tool.
ACU-RITE 3500i 27 2.1 F undamentals of P ositioning Reference system A reference system is required to define po sitions in a plane or in space. The position data are always referenced to a predetermined point and are described through coordi nates.
28 2 Machini ng Fundamentals 2.1 F undamentals of P o sitioning Designation of the axes on milling machines The X, Y and Z axes on your milling machine are also referred to as tool axis, principal axis (1st axis) and minor axis (2nd axis). The assignment of the tool axis is decisive for the assignment of the principal and minor axes.
ACU-RITE 3500i 29 2.1 F undamentals of P ositioning Setting the pole and th e angle reference axis The pole is set by entering two Cartesian co ordinates in one of the three planes. These co ordinates also set the reference axis for the polar angle PA.
30 2 Machini ng Fundamentals 2.1 F undamentals of P o sitioning Angle Measurements Polar measurement of angles is referenced from the 3 o'clock position (0 degrees). Positive angles rotate in a counterclockwise directi on; negative angles rotate in a clockwise direction.
ACU-RITE 3500i 31 2.1 F undamentals of P ositioning Absolute and incrementa l work piec e positions Absolute work piece positions Absolute coordinates are position coordinates th at are referenced to the datum of the coordinate system (o rigin). Each position on the work piece is uniquely defined by its absol ute coordinates.
32 2 Machini ng Fundamentals 2.1 F undamentals of P o sitioning Setting the datum Fixture Offsets A production drawing identifies a certain form elemen t of the work piece, usually a corner, as the absolute zero datum.
ACU-RITE 3500i 33 2.1 F undamentals of P ositioning Example2: SetZer o See "Absolute Zero Set" on page 138 for more information on using the SetZero cycle. The work piece drawing shows holes ( 1 to 4 ) whose dimensions are shown with respect to an absolute datum with the coordinates X=0 Y=0.

ACU-RITE 3500i 73 4.2 T ool D ata Tool-Length Offsets Tool-length offset is the di stance from Z0 Machine Home to the tip of the tool at the part Z0 (the surface of the work). Tool-length offsets allow each tool used in the part program to be referenced to the part surface.
74 4 Tool Management 4.2 T ool D ata With the tool in the spindle, carefully jog the tool down until it touches the top surface of the work piece. This is referred to as “Part Zero”. Touch the Teach button. The 3500 i calculates the tool length offset for the selected tool putting the data to the length column.
ACU-RITE 3500i 75 4.2 T ool D ata Tool Radius Compensation When tool compensatio n is not active, the CNC positions the tool's center on the programmed path. When prog ramming a part profile, the cutting edge must be half a diameter away from the path.
76 4 Tool Management 4.2 T ool D ata Contouring with radius compensati on The tool center moves along the contour at a distance equal to the radius. “Right” or “left” are to be understood as based on the direction of tool movement along the work piece contour as viewe d from behind a moving tool.
ACU-RITE 3500i 77 4.2 T ool D ata Radius compensation : Machining corners Outside corners: If you program radius compensation, the CNC moves the tool around outside corners on a transiti onal arc. If necessar y, the CNC reduces the feed rate at outside corners to reduce machine stress, for example at very great changes of direction.
78 4 Tool Management 4.2 T ool D ata Ramping into a Compensation Move Entry moves allow a smooth transit ion into a contour. Allowi ng a way to avoid areas you do not want to affect with the tool when entering a contour, Entry Move button (G36). If an entry move without compensation is re quired, program a tool with “0 ” radius.
ACU-RITE 3500i 79 4.2 T ool D ata Arc Tangent Entry Mo ve In an arc tangent entry move the t ool approach es the contour through an arc and enters tangent to the first move of the contour.
80 4 Tool Management 4.2 T ool D ata Special Code: Temporary Change of Tool Diameter To change the tool radius in order to leave stock for a finish pass, program the “stock-variable”. The var iable assigned for this function is #1030. Example: 120 #1030 = .
ACU-RITE 3500i 81 4.2 T ool D ata Tool Compensation Path Path of Tool Dur ing Tool Compensation In linear-to-linear or linear-to-circula r moves, the position at the end of the startup block Compensation LEFT (G41), or Compensation RIGHT (G42), is perpendicular to the next programmed move in the plane.
82 4 Tool Management 4.2 T ool D ata Intersecting Points You cannot program a plane change during tool compensation. However, a 2-axis move off the currently active plane is allowed. For example: The active plan e (compensation in XY). You program an XZ or YZ move.
ACU-RITE 3500i 83 4.2 T ool D ata General Precautions When you program tool path instead of part edge, a negative diameter in the Tool Table effectively changes the moves during compensation. Third axis moves (not in the acti ve plane ) are permitted during compensation.
