Newall Digital Readouts are some of the most feature rich DRO systems in the market today. Here is a brief list of some of the more popular features and functions included in Newall's DP500, DP700, and DP1200 DRO Systems. For more details on how to use these functions, take a look at Newall DRO User Guides.
| Model | Type | Feature/Function | Description |
|---|---|---|---|
| DP500, DP700, DP1200 | Setup | Linear Error Comp | In this mode, you can apply a single constant correction factor for each axis to all displayed measurements. You calculate the correction factor, and specify it in parts per million (ppm). In this mode a single constant correction factor for each axis is applied to all displayed measurements. |
| DP500, DP700, DP1200 | Setup | Segmented Error Compensation | Each Correction Point is measured with respect to the Starting Point - zero - which is usually set close to one end of the scale. |
| DP500, DP700, DP1200 | Setup | Radius/Diameter Readings | The radius/diameter function allows the operator to display actual (radius) or twice-actual (diameter) measurements for each axis. This function is generally used in turning applications, such as the cross travel on a lathe where you want to display the diameter reading rather than the radius. |
| DP500, DP700, DP1200 | Setup | Switchable Resolutions | The resolution settings available for each axis depend on the inch/mm setting and the accuracy of the scale. |
| DP500, DP700, DP1200 | Standard | Absolute/Incremental Readings | Each DRO display has a dedicated key to switch the positional displays between absolute (abs) and incremental (inc) measurements. |
| DP500, DP700, DP1200 | Standard | Inch/Metric Instant Conversion | Each DRO display has a dedicated key to switch the positional displays between imperial (inch) and metric (mm) measurements. |
| DP500, DP700, DP1200 | Standard | Datum Preset/Zero Reset | Each axis can be set to zero independently or a numeric entry can be entered into the desired axis. |
| DP500, DP700, DP1200 | Standard | Undo | The last 10 positions/numeric inputs are stored and can be accessed using the undo feature. |
| DP500, DP700, DP1200 | Standard | 1/2 Function / Center Find | Each DRO has a dedicated key to half the value in any axis. This is done by initiating the half mode and selecting the required axis. |
| DP500, DP700, DP1200 | Standard | Reference Point (Digifind) | Digifind eliminates the risk of losing your position and datum Set-Up. With Digifind, precise Set-Up of a workpiece is carried out only one time. Digifind allows a quick means to find the datum if lost. |
| DP700, DP1200 | Standard | Feed Rate Display | mm per second for mm mode, inches per minute for inch mode |
| DP700, DP1200 | Standard | RS232 Output | The current axis data for the axes available on the system are transmitted. |
| DP1200 | Standard | Programmable Memory/Teach | Teach mode is an easier way of calculating linear errors using the DP1200 to automatically calculate the error, by comparing the actual measurement and the physical movement. |
| DP1200 | Standard | Real-Time Tool Path Graphics | - |
| DP500, DP700, DP1200 | Milling | Bolt Hole Circle Routine | The DRO calculates positions for a series of equally spaced holes around the circumference of a circle. Once the DRO completes the calculations, the axis displays show the distance to each hole. |
| DP700, DP1200 | Milling | Arc Contouring | The DRO calculates positions for rough machining an arc or radius. The message display prompts the user for various parameters it needs to do the calculations. Once the DRO completes the calculations, the axis displays show the co-ordinates, which are point to point positions along the arc. The operator works to zero for each hole location. |
| DP700, DP1200 | Milling | Line Hole Routine | The DRO calculates positions for a series of equally spaced holes on a line. The message display prompts the user for various parameters it needs to do the calculations. Once the DRO completes the calculations, the axis displays show the distance to each hole. The operator works to zero for each hole location. |
| DP700, DP1200 | Milling | Polar Coordinate Readings | The Polar co-ordinate function enables the operator to convert the displayed data from the conventional cartesian co-ordinates (X,Y) to polar (length + angle) co-ordinates for any plane XY,XZ or YZ. |
| DP1200 | Milling | Skew | The Skew Feature provides capability for the DRO to find the skew angle of a part. It is very useful for the machine operator to know if the part is square to the bed. It can also be used to find other angles on the workpiece. |
| DP500, DP700, DP1200 | Lathe | Tool Offsets | The Tool Offset function allows the operator to enter and store offsets for a range of tools.This enables the operator to change tools without resetting absolute zero or datum. Using tool offsets ensures that diameter and length measurements will remain consistent after tool changes.This speeds up tool changes and increases productivity as it eliminates the need for the operator to stop and manually measure the diameter. |
| DP500, DP700, DP1200 | Lathe | Multiple Tool Datums | If several tools are required for work on a particular piece. For example there might be a roughing tool, a finishing tool, a thread cutting tool, ID boring tool, etc. A separate datum can be set for each tool. Changing one tool does not affect the other tools. |
| DP700, DP1200 | Lathe | Axis Summing | The summing function allows the sum of two selected axes to be displayed. |
| DP700, DP1200 | Lathe | Taper Calculations | The taper function shows the angular displacement of the displayed (X,Z) position. |
