A Case-Based Reasoning of Computer-Aided Process Planning System for Rotational Parts
1) In the pdf version state that “Generate the feature process plan form scratch” is that meant that each new feature or its variation imply begin with a new register?
2) The paper mention that it is a “case-matching methodology which is multi parametric and absolute”, considering the tolerance of the parameters how this study can assure that the case found is the optimal one and it is not a new case for the data base (considering that the tolerances applied may be varied from process to process and from customer to customer)?
3) How deal with the problem of founding the optimal case?
The approach is interesting, but it is difficult to assess the number of cases which has to be stored before obtaining good results when a new problem has to be solved. Do you have information available on this ?
The Case-based reasoning is an artificial technique based on previous cases and check similarity for arraived to the best solution, therefor this is the best method to obtain the omtimal process planning depends upon actual previous solution and from it we obtain the G code program and make a check on the CAPP by enter the G-code for the solidworks and obtain the geometry. The fuethet extend this work by applied it on the primistic parts and we can applied Case-Based Reasoning on the maentainance and scheduling.
For any future quistions : And I hope to co-operate with you and work in this point or any points you suggiste.Mohamed abdel gawad
My CAPP system can generate the process planning from scratch based on knowldge based built in the database. The system search and compare the new feature to the features in DB and if not access with any in DB the program generate the process of it based on knowldge based, therefore the system not depend only on the previous features but the time of generate is increased.

generate the feature process plan from scratch didn't mean each new feature creature from scratch but start search for similar case and choose the nearest feature to it and if the same feature but different in diminesion or tolerance the system adjust the properties of feature "take the same operation but in determine the machining time according to the new dimensional of the new feature and take the cutting condition to meet its spasifications".

Can you apply the same method that you used in automatic generation of process planning for prismatic parts by using design by features ? If you used the artificial neural networks for development of machining process panning, are you going to find the same results?
I can apply the same method in prismatic parts by using design by feature but this is demending most higher database than rotational parts. when used artificial neural networks in CAPP I didn't know the aviable package in ANN using in CAPP but if we use any for generating CAPP for any workpiece it must be the same processes required to obtain the part but the change in details. In CBR, we obtain the most cutting condition and we can generate the alternative CAPP for parts to meet requirment if there are a bottle neck in scheduling.
I've seen a similar paper to this one using an artificial neural network approach to process planning for cylindrical components in what way do think this approach is better or worse, and how do you think you could further extend this work.
