CappsNC from Applied Automation Technologies allows offline programming and provides users the ability to run any CNC machine tool as a CMM, using measurement data to automatically improve the machining process. "To perform the complex mathematical calculations required for the metrology based real-time decision making, a CMM software needs to be integrated within the manufacturing system. CappsNC is the version of CappsDmis CMM software that can program any machining center to perform advanced measurement, metrology and GD&T calculations using the standard DMIS language. Offline programming with automatic collision avoidance and 5-axis path generation allows programming with any machine configurations including multi axis mill-turn machines," said a company spokesperson.
Offline Programming
A CAM style programming environment with a realistic machine tool virtual model, simulation capabilities, automatic path generation with collision avoidance and complete geometrical fitting and tolerancing functionality are provided within the CappsNC software. Multi-View graphics view with easy UI programming environment makes it easy to create programs for any machine tool configurations.
Online Execution
CappsNC can connect with most machine tool controllers with a real-time direct interface. A G-code program is created from the DMIS program so that the machine tool can be used just like the regular cutting programs by the operator or by an automation cycle. Live 3-D simulation is displayed in CappsNC graphics and calculations are performed as soon as data are collected. The calculated metrology characteristics, such as best-fitting a data set to a CAD model, are used as a part of the on-the-fly decision making and written back to the machine tool controller as a part of the adaptive cycle.
Multi-Sensor Software
CappsNC uses its own generated macros and does not require any OEM generated macros. This allows it to be probe brand independent and can work with the existing probes available on the machine. CappsNC can also work with different probe types such as:
Kinematic Probes
CappsNC can generate vector-based calibration to compensate any lobing errors of the kinematic triggering mechanisms of these probes.
Strain Gauge Probes
Automatic calibration cycles are generated to calculate probe run-outs, effective radius and 5-axis head offset errors. This not only eliminates the need to independently preset the probes, but it allows users to quickly check any 5-axis head misalignments of the machines.
Analog Probes
Automatic contact scanning paths are generated for any geometrical curves or surface measurements such as airfoil or gear profiles. Advanced data filters and automatic comparison to CAD models with 3-D best-fit algorithms allow quick calculation of characteristics for on machine automatic decision making.
Blue Light Laser Sensors
CappsNC has advanced point cloud functionality that is utilized with high density data collection by using a laser sensor. Laser scan programs are automatically generated by converting NC cutting programs or directly from CAD models. Automatic geometric feature extraction provides quick data analysis for reporting or G-code program adaptation to the actual part shape.
Benefits
"While CappsNC can operate any machining center like a CMM, the goal is much bigger than simply performing on machine measurements," said the spokesperson.
Pre-process benefits:
- Quick monitoring of the machine tool geometry by using an artifact
- Advanced 6DOF part alignment and work offset creating
- Re-posting of 5-axis NC programs for non-rigid parts such as composites.
In-process benefits include:
- Dynamic cutting tool offset and wear compensation. Measures and provides feedback for actual cutting tool shapes during machining process
- Provide automation decision making based on measurement results.
Post-process benefits include:
- Eliminate the need to move parts back and forth between a CMM
- Create complete measurement reports and graphically display or save on servers
- SPC data base and process charts.
