Like all programmers I strive to put out the best programs that I am capable of. I check to see that everything is in the program that needs to be there. Sometimes the macros that I use may not always (<1% of the time) work correctly depending on the machine. The operators do have the responsibility of proving out a program (usually to increase productivity). The machines that we use in our shop are not new machines, all are generally late 1980's to early 1990's vintage machines.
I believe this is what you call job security. If a job is run and the program becomes a proven program, why re-code it? We utilize a library where the machines in our shop can pull up programs and load them into the machine. Due to raw material differences (castings) the operator may have to make certain edits to achieve the optimum machine time (s) for running a particular part. Once the part has been run. The program is sent back to a download file. I then compare the two programs to see if any edits were made and if so were they necessary. This takes a couple of minutes. I then add a (MSG, RAN BY ??? EDITS OR NO EDITS AND THE DATE), this lets the next operator who runs this program again know what was done and why.1.) The programmers are allowed to take the time to get the programmes correct on the SmartCAM screen before prove-out. Nobody is ever heard to say, "That's near enough, I'll edit the file on prove-out."
2.) No 'code' files are kept on the shop floor, after running the batch the file is deleted, the part is re-coded for the next batch.
I personally find this hard to believe since there can be many factors involved. Age of the machine, set up of the machine, weather / shop conditions, and materials. All of these factors hence negate this claim in my opinion.
3.) The SmartCAM shape file is therefore absolutely the correct file, there is never any doubt.====================================================================== To find out more about this mailing list including how to unsubscribe, send the message "info mfg-smartcam" to [EMAIL PROTECTED] ======================================================================
