Mahr Federal wireless data transmission capability is now integrated within its families of MarCal digital calipers and MarCator digital indicators. Both products send data to a small i-stick receiver resembling a USB flash drive. MarCom software eases data acquisition by enabling users to take a measurement and transmit measuring data directly into Microsoft Excel or via a keyboard code into any Windows program, without the need for external transmitters or cables, the company says. Additionally, users can apply the wireless data collection capabilities to existing SPC applications.

Low-power transmitters in these digital calipers and indicators eliminate the need for expensive add-on transmitters that can consume excess power, make gages bulky and interfere with portability, the company says. Each MarConnect i-stick wireless receiver supports as many as eight measuring instruments with a range of 12 m, suitable for most benchtop or workstation applications. The MarConnect integrated wireless interface is active as soon as the i-stick is plugged in, and each caliper/indicator is identified by signal coding in the MarCom software so that there is no signal confusion.

The company’s line of mechanical comparative gages can also be upgraded for wireless data transmission with the addition of a MarCator 1086 or 1087 wireless digital indicator. With the addition of wireless transmitters, digital indicators can help speed part inspection times, reduce the complexity of data collection and improve the quality control process.

    Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
