Ways of Students Training Aimed at Analytical Skills Development while Solving Learning Tasks

The article considers the problems of students training to solve learning tasks in technical universities, as well as training of high-school students, who are going to enter technical universities. The functions of tasks, causing the importance of their application in learning process, are specified. The system of methods is given which allows a successful development of analytical skills of students during solving physics and chemical problems. The features of analysis during solving physics and chemical problems are demonstrated. Results of experimental work, supporting the effectiveness of the stated methods, are given herein

Controlling the type and the form of chip when machining steel

The type of the chip produced in the process of machining influences many factors of production process. Controlling the type of chip when cutting metals is important for producing swarf chips and for easing its utilization as well as for protecting the machined surface, cutting tool and the worker. In the given work we provide the experimental data on machining structural steel with implanted tool. The authors show that it is possible to control the chip formation process to produce the required type of chip by selecting the material for machining the tool surface
