章節(jié)摘錄
The debugging process begins after the part program has been successfully loaded. First, the setup person locks the machine and runs the program using only the output from the MCU. This is done to check if the controller recognizes all the codes in the program. If this test is successful, the program can be run with the machine Z-axis locked. This will guard against any possible collisions between the tool and the work holding or part itself. Next is the so-called "dry" run with the part removed. During this test the setup person slows down the rapid feeds and speeds up the actual feeds. These tests will indicate whether the program runs and if there are any extraordinary moves which could cause a collision of the work and/or work holding with the cutting tool. To verify if the program produces a proper part, a blank must be loaded and cut. I~ the production blanks are made of costly material, some shops may first cut a test part using aluminum, wax, wood and so on. This saves on material, cutting tools, and prove-out time. The actual cutting test is run in single-block mode(versus automatic mode). This is done to give the setup person time to see the effects of each command and aids in spotting a wrong move. The program is further optimized by eliminating any unnecessary moves. After the part is completed, it is measured to determine if the drawing, operation sheets, and programmer specifications have been satisfied. Adjustments are made. If necessary, another part is made and checked by the quality control department. If everything is found to be satisfactory, the part goes into production. ……
