Cutting Modes

The justification of the feasibility of determining the cutting modes when processing with a blade tool with optimization to minimize the wear of the cutting wear is given, i.e. for its maximum resistance and at the same time to ensure the required quality indicators of the material of the surface layer of the part after processing. The initial data for the calculation and examples of calculating the cutting mode and surface layer quality indicators are given. Nomograms for determining the cutting modes, taking into account the quality indicators of the surface layer, are of practical interest for technologists of machine-building enterprises.

The Impact

The problems of analyzing metallographic images and the method of their solution using modern software for the analysis of metallographic images are described. There is given an analysis of microstructure images as the main indicator of the surface layer quality by the example of studying the research results of strain wave hardening combinations and chemical-thermal treatment, in particular the influence of previous strain wave hardening and subsequent thermal and chemical- thermal treatment on the alloy steel microstructure or previous thermal and chemical- thermal treatment and subsequent strain wave hardening. On the basis of the analysis the effectiveness of strain wave hardening and chemical and thermal treatment is established.

Blade Production

The existing technologies of production of compressor blade butts related with traditional machining methods, including broaching and milling. Application of these machining methods requires further superfinishing operations to ensure the required quality of compressor blades. The automated highly-productive grinding of blade butts is an effective method to improve performance and quality of blade production. The technologies of profile and contour grinding of blades of a rotor and a compressor stator provide an automated machining of the outer parts contour in the same coordinate system, implement machining based on 3-D models of theoretical blade surfaces, ensure the required quality parameters of the part surface layer without additional finishing operations.

Nickel electroplating process at UD Barito Electroplating is a modern methodology installed in an open complex environment and at controlled temperature with trust consideration of specimen composition. The evaluation of process at UD Barito has been undertaken by considering Stainless steel AISI 316L as specimen through a conventional nickel electroplating process. This paper presents the proper scientifically tool to be used at UD Barito in order to meet the time required and the surface layer quality of the electroplated product. The use of ultrasonic to replace air compressor assembly does not cause any harm to the surface finish smoothness and the quality of plated specimen given that the process is conventional. Concerning the process of 10 min compared up to 15 min of the process at UD Barito; showed the facility of ultrasonic assisted the electroplating process. This process is also a useful method in maintenance activities for surface cleaning and for product surface-layer quality enhancement through the coating process. From the data analyzed, the specimen has a hydrogen embrittlement rate range between 20 to 65% of Rockwell scale HRC52.
