Ištrauka

During the course "Manufacturing technology of machines" there is taught about production processes. Like a practical part of this course is project. The main task of the project is to describe the manufacturing process of the part in details (the part drawing and the task is given by a teacher and is as Appendix 1 and 2). The project consists of such parts-problems:
General work-specific calculations necessary for further design;
Analysis and selection of the blank of the part;
Analysis of the drawing of the part and its technical specifications;
Analysis of machining operations, operation sequence and substantiation of the part location in operations;
Design of machining plan;
Computing and selection of machining allowances;
Design of operational technology, calculation of rates of cutting;
Time rating;
Variant comparison;
Design of the department for part production;
Design of a special fixture for surface A machining operation;
Analysis of the accuracy specification ensured by the fixture;
Design of special measurement device to measure parallelism and analysis of measurement accuracy.
All these problems are discussed in the following chapters. The problems are going to be solved mainly using textbook "Production technology of machines and instruments" and other handbooks, the detail information of the used textbooks are presented in references.
The necessary drawings of the course project will be drawn using Autodesk Inventor Professional 8 and AutoCad2000 software.

According to the methodical literature the first task in manufacturing process is to decide the production type (mass, big batch, etc.) and roughly to calculate the production time of one part. The part which manufacturing process I will describe is quite complex and my experience of manufacturing process is too little that I could evaluate more or less precisely the producing time.
I work in company with universal milling machine only for three months and from the first view at the drawing (of course knowing my possibilities) I will say that to manufacture such a part for me alone it will take 4±1 hours. That is what I can say from my own experience. ...
