Delcam will demonstrate all three versions of its PowerINSPECT inspection software at the Aerospace Testing International exhibition to be held in Long Beach, California, (November 8-10). In addition to the manual version of the software, recent releases will be on show that support CNC-based inspection techniques and On-Machine Verification.
The latest release of the manual version has made the software even easier to use and gives even more versatile reporting. Improved graphics, including new shading options, make it simpler for users to develop the required inspection routine while new options for inspection simulation give even greater confidence in the results.
Both fully shaded and transparent models can be used in reports to make the results even easier to understand. In addition, the association of proportional length needles with the PowerINSPECT coloured dots gives a clearer indication of the degree to which any point is out of tolerance.
The newer CNC version allows PowerINSPECT to be programmed off-line for the inspection of sample parts against a master CAD model during production. Previously, the software could only undertake repeated inspection cycles through teach-and-learn methods.
This new off-line programming functionality will increase the productivity possible from any CNC co-ordinate measuring machine by eliminating the interruptions needed for manual programming. Full simulation capabilities within the software allow the proposed inspection sequence to be tested on the computer, before being transferred to the CMM.
An additional benefit of the PowerINSPECT version for on-machine verification is for those companies that do not have existing inspection capabilities. Most modern machine tools either come with, or can be retrofitted with, probing capabilities to assist in the set-up of the job. With the OMV version of PowerINSPECT, this same equipment can now be used for verification at little extra cost. The ability to program and simulate complete verification sequences off-line means that there can be minimal interruption to the machining operations.
On-machine verification can give huge time savings by enabling the quality of the component being machined to be monitored at all stages in the manufacturing process. This will allow any errors to be detected earlier, and so corrected more quickly and at lower cost. For example, it will be possible to check that the correct amount of stock has been left on the component after a roughing operation, rather than having to wait until all machining operations have been completed before discovering that an error has been made.
Similarly, the extent of any damage caused, for example, by a tool breakage, can be assessed accurately and a decision made immediately to determine whether the part can still be completed within tolerance or whether it will have to be scrapped.
On-machine verification will also benefit companies with customers that insist on independent inspection of their work. By carrying out an initial verification on the machine, errors can be detected, and corrected, that might otherwise not be found until after the component had been shipped to the inspector.
The program gives both quick and easy comparison of tooling and sample components against CAD data, and produces clear, comprehensive reports that can be understood by everyone involved in the product development process, not just inspection specialists.
