Example 4Baffle Plate is held in a precision vice to machine the top face features in operation 1 1 and then held in a fixture tomachine the outside profile in operation 2. The Blank part is cut to 106 x 300 x 12 mm.We have combined operation 1 and 2 together on the same page and commented out the M30 at the end ofoperation 1. Then after running the Solid Animation of both operations, see below we have a good representation ofthe finished part. Try to write the program using the Cimco Editor and only use the program listing below as areference.14
End of Operation 1 Program 0100.MPFCut and Paste Operation 2 to the samepage as Operation 1. Comment out theend of Operation 1 so that Backplot willread past the M30 command andstraight onto the operation 2 programSee the part machined complete below: The Operation 1 and 2 are listed below as they would be in the CNC controlas Program 0100.MPF and 0101.MPF15
