### Sheffield Interface

The Sheffield interface is used with Sheffield machines. No machine parameter file is needed from the original system to run this interface. On the Sheffield CMM, PC-DMIS does not control when the CMM is in manual control or DCC control. The buttons to control this are on the jog box. If the CMM has a rotary table, PC-DMIS requires a separate Tech80 card for the rotary table encoder.

Before starting PC-DMIS, rename the sheffield.dll to interfac.dll.

The Machine Option dialog box has four tabs for the Sheffield interface:

Interface tab

See the "Sheffield Interface tab" topic.

Axis tab

See the "Assigning the Machine Axes" topic.

Resolution tab

See the "Setting the Axes Scale Factor" topic. Default is X=1000, Y=1000, Z=1000.

Debug tab

See the "Generating a Debug File" topic.

Note: Additional information for this interface is provided in the Machine Interface Installation Manual (MIIM).
