O.k. here is the stuff. In the zip file is a PDF print out of the dwg file, there is a dwg file, an iges file and a dxf file. It is all 2-d data.

The goal is to see how long it takes to do the programming on the block assuming it came from your "native" cad system. In other words, don't count converting this to the format you need to program as part of the programming time. For example, if you want to program it from a solid model, keep track of the time is takes to convert it to a solid model separately, but please tell us the conversion time also as it might be interesting to see.

Start with the assumption that the block is cold rolled steel bar stock saw cut to 5.12 inches long, the other dimensions are 2.000 x 4.000 as crs comes in pretty close to size.

To make sure everyone compares apples to apples the following should be programmed:

1. Square the block up on all 6 sides leaving 0.005 grind stock on each side. Do this with whatever machining practices you deem most efficient.

2. Machine 0.020" chamfer on all the edges of the block.

3. Do all of the drilling etc. including milling in the text 0.015 deep approx.

4. Program also from back side of the block to chamfer all the holes drill thru or to finish an features that could not be reached from the top side of the block.

5. Include in your time study a breakdown of how many different setups in the vise
(or however you would hold the block) are necessary to complete the block.

6. Happy programming.

7. If you have any questions that need to be asked, do not include them in your programming time..... My apologies if it is not all perfectly clear.....

Any other "Rules" you guys think should apply before getting started?

Thanks, Bob.
