The ND 1200R is an advanced digital readout (DRO) system for radial drilling machines using analog or TTL encoders. The system allows the operator to directly enter either cartesian or polar coordinates for target positions. This alleviates the requirement of either pre-drilling holes or a previous operation of marking out the holes on an expensive machine elsewhere. The system defaults to cartesian coordinates when entering target positions and polar coordinates when navigating to a target.

The following functions are available in the ND 1200R:

 Reference mark evaluations for distance-coded and single reference

encoders

 Linear error correction

1.1 ND 1200R Overview

Establishing a repeatable machine zero

If your ND 1200R was configured to establish a machine zero upon power-up, a message will be displayed asking you to cross reference marks or enter hard-stop axis reference positions. The machine zero is used by the ND 1200R to apply error correction data. To establish a repeatable machine zero you must either:

 Move the stage to have encoder reference mark crossings

recognized on each axis or

 move the stage to the hard-stop reference position and press

ENTER on each axis when no encoder reference marks are present.

If the requirement to cross reference marks is bypassed by pressing the CANCEL soft key, error correction data that might be stored in your ND 1200R will not be

A repeatable machine zero is required for the DRO to apply the calibration chart to the machine geometry correctly.

It is not recommended to use the machine without active calibration. This would lead to unknown position errors.

Usually the calibration is based on referencing via reference marks on the encoders. To establish the machine zero after power-up:

 Move the stage to have the reference mark crossings recognized on

each axis.

If the machine zero is determined via hard stops:

 Move the stage to the hard-stop reference position and press

Select a probe diameter

A probe is required to zero the axes on a workpiece. The diameter of the probe can be adjusted. This is needed to compensate for the offset of the part from the edge of the probe being used.This diameter is either the diameter of the touch probe or hard probe being used.

To assign a probe diameter:

 Press the DATUM soft key.  Press the PROBE soft key.  Enter the probe size.  Press the FINISH key.

1.3 Preparing to drill

26 1 Operation

Aligning the part to an axis

Accurate drilling requires the part to be perfectly aligned along an axis. Misaligned parts result in targeting errors. Use the SKEW function to convert machine coordinates to part coordinates and compensate for part misalignment. Perform a skew each time a new part is mounted.

Measure a skew line by probing a straight edge of the part on a major measurement axis or by probing two or more pre-drilled holes.

The skew alignment edge or line must be oriented within 45 degrees of the measurement axis.

Aligning a part edge to an axis

To align a part edge to an axis:

 Align the part on the stage.  Press DATUM>SKEW.  Probe a minimum of two points along a part edge. In the example

shown here, the part is aligned to the X-axis by probing three points along the bottom edge of the part.

 Press the FINISH key.

The part could alternately have been aligned along a vertical edge to the Y-axis.

The orientation of the cartesian coordinate system depends on the type of machine. It can be changed by the supervisor (password required).

1.3 Preparing to drill

Three points are probed to align the bottom edge of a part to the X-axis

ND 1200R Radial 27

Aligning a pair of holes to an axis

There are certain times when the part needs to be aligned on the center of two pre-drilled holes.

To align a pair of holes to an axis:

 Align the part on the stage.  Press DATUM>SKEW>HOLE.  Probe a minimum of three points around the edge of the first hole

to be used in the skew.

 Press the FINISH key to complete the first hole measurement.  Press the HOLE soft key.  Probe a minimum of three points around the edge of the second

hole to be used in the skew.

1.3 Preparing to drill

 Press the FINISH key to complete the second hole measurement.  Press the FINISH key to complete the skew.

Distributing the probed points evenly around the circumference of the hole will provide a more accurate placement for the center of the hole.

Three points are probed for each hole to align the center of the holes with the X-axis

28 1 Operation

Establish a datum

A datum can be created from a probed point, the center point of a probed hole or a point created from the intersection of the skew alignment line and another line perpendicular to the skew alignment line.

Setting a datum from a probed point

To set the datum from a probed point:

 Press DATUM>ZERO>XY.  Probe the desired location of the datum.

Setting a datum from a skew line

The first point of a skew line is automatically set as the datum. The datum is most commonly created from a point that is the intersection of the skew alignment line and a second part edge line.

To set the datum from a skew line:

 Perform a skew alignment.  Press DATUM>ZERO.  Press the soft key for the axis to zero along (the same axis used for

the skew line).

 Probe a point on the part edge perpendicular to the skew line. The

datum is now set to the intersection of the skew alignment line and the probed part edge.

Setting a datum on the center of a hole

The center of a hole is found by probing a minimum of three points on the edge of the hole.

To set the datum from the center of a hole:

 Press DATUM>ZERO>HOLE.  Probe a minimum of three points around the edge of the hole.  Press the FINISH key.

1.3 Preparing to drill
