I would assume that the data feeding into the computer is correct, their multi-million-dollar CNC equipments are great, and the operators (if any) are professionals. But why is the product quality low? and what's human being's factor in this process? Return to NIB Stainless Luger. If parts do not even fit, sounds like a parts gun, where did the precision lost in the manufacturing process.... cutting and milling was controlled by computer? |

Operator/coder can specify spindle speed too fast (or too slow); feed rate may be too high (or too low); depth of cut may be...yup, you guessed it...too much or too little...  It's not all that much different from manually machining the piece...You just approach it differently...and you try out a new program on inexpensive workpieces; not expensive forgings (or in the case of the SS Lugers, investment castings, IIRC)... It's not something you can learn in a day...a good machinist learns his trade over a lifetime...and is still learning...  I wish I was a good machinist...I'm running out of time...
