Electrode design drawings automatic foolproof improvement measures Production Technology Section II: Guo Shujun in the past, the drawings issued by our company's electrode design did not have automatic foolproof measures, just write 'look at the picture' in the important remarks column, but in the actual production process, the on-site operator often forgets to look at the picture for convenience or other reasons, resulting in the omission of some important matters needing attention, cause abnormal quality.
Because the company has been improved at present, EDM processing has realized automatic generation of program processing by scanning two-dimensional bar codes, and this convenient processing method has also brought some inertia to field operators, under what conditions, the bar code is automatically scanned and processed without looking at the drawings, resulting in the omission of some important information on the drawings, resulting in abnormal quality :(As shown in Figure 1)(Figure 1)
: Although there are notes on the drawings, the actual operation can be easy to see: Solution: for some important information, we indicate in the remarks column, for example, the system will automatically alarm to stop EDM processing program for important information that may cause abnormal quality, such as electrode side beating, fixture removal processing, C- axis swing angle processing, etc.
Force the operator to look at the picture and check the specific alarm reasons, so as to adopt corresponding processing methods to ensure the quality. Put an end to the occurrence of abnormal quality. (As shown in Figure 2)(Figure 2)
: For some important information, we indicate in the remarks column that the system automatically stops the alarm: Summary: small improvement, big effect.
Through this improvement, the system is forced to automatically stop the machine tool after identifying important information, reminding the operator to check the specific requirements on the drawings, so as to take corresponding measures to ensure the processing quality. NJPE-
