Delcam will demonstrate the company’s unique adaptive machining technology for aerospace manufacturing and repair on booth 207at the AeroDef Manufacturing exhibition, to be held from 25th to 27th February at Long Beach Convention Centre.  Adaptive machining combines Delcam’s industry-leading CAD, CAM and inspection software to give improved quality, reduced scrap, increased productivity and shorter delivery times.

In an ideal world, any manufacturing process would be capable of producing a consistent quality of part every time.  In reality, there are many variables which, if ignored, can result in poor quality parts being produced.  Delcam’s complete automated CAD - CAM - CNC machine process can incorporate in-cycle inspection to constantly check on progress, making sure parts are produced right the first time.  Software programs from Delcam can be combined together as one complete solution or used as standalone programs, either to remove bottlenecks in a current process or to replace old or obsolete software. 

Successful projects must start with a high-quality CAD model.  PowerSHAPE, Delcam’s powerful, versatile CAD software for the design of complex 3D parts, lets users find and fix any issues that could cause a hold-up in production, such as a gap in the model that could lead to gouging during machining.  Even better, all of these tools are available where you need them – on the shop floor.  By preparing or repairing CAD models with PowerSHAPE, users can reduce lead times and maintain part quality.

The next step is to use a CAM system that will be able to cope with the ever-increasing production demands.  PowerMILL from Delcam helps manufacturers to create perfect toolpaths first time, every time.  The latest changes in PowerMILL’s extensive functionality for five-axis machining increase the number of options for tool-axis definition.  For raster toolpaths, the lead and lean angles can now be defined relative to a contact normal.  In addition, better control is now possible for the tool-axis definition when using the "To or From a Point” and "To or From a Line or Curve” strategies.  These improvements make it easier for users to control the contact angle between the cutter and the part, and so set the optimum cutting conditions for efficient machining and quality of surface finish.

In a busy production environment where it is essential that parts are produced as quickly and cost effectively as possible, FeatureCAM, Delcam’s feature-based CAM software, is the perfect solution.  It automates the creation of reliable NC code for a wide variety of machine tools.  The 2014 version has just been released with a number of new options for turning, four-axis rotary machining and turn-mill operations.  Other enhancements in this release include more strategies for two-axis finishing and easier programming of probing sequences.

The ability to incorporate probing routines into machining programs was added in FeatureCAM 2013.  These routines make it easier to undertake unsupervised production operations by allowing automated checks to be carried out before, during and after machining.  Programming of these operations has been made easier and quicker with the new ability to incorporate decision-making with built-in options in the software, instead of having to hand-write toolpath edit commands.  For example, it is now easier to include a re-machining command if the probing results show that more material needs to be removed from the part.

The final step is inspection.  PowerINSPECT is firmly established as the world’s leading hardware-independent inspection software.  It combines the ability to work with all types of inspection device, including probes on machine tools, with a comprehensive range of inspection routines for taking simple measurements, for inspection of geometric features and for analysing complex 3D surfaces.  The resulting reports present detailed information in an easy-to-read format, that can be understood by all engineers not just inspection specialists.

The 2013 R2 version of PowerINSPECT offers faster programming and inspection, plus even easier-to-read reports.  It includes a new method for automated inspection of edges of parts, improved display of deviations, support for a wider range of geometric features, more flexible simulation and additional dimensioning options for radial features.
