ASSEMBLY PRODUCTION: PROBLEMS AND SOLUTIONS The article is dedicated to 155th anniversary of the Moscow Polytech
The article analyses the existing problems of assembly production in mechanical engineering. It identifies issues that need to be addressed at the industry and state levels.
GEOMETRIC ACCURACY OF METAL CUTTING MACHINES: COMPENSATION, CORRECTION, CONTROL. PART 2 The article considers the issues of structural accuracy of metal-cutting machines.
It presents the structural components of linear and angular geometric errors of metal-cutting machines. Three groups of accuracy models of metal-cutting machines are presented, differing
in the number and type of input components, as well as the result achieved by the accuracy control system created on their basis.
FUNCTIONALITY OF THE MODERN CAM-SYSTEM FOR 4- AND 5-AXIAL MACHINING AT CNC PROCESSING CENTERS Using the ADEM system as an example, the functionality of a CAM system is described, which allows for the preparation of control programs for efficient 4- and 5-axis machining of complex parts at CNC machining centers.
SmartControl – AUTOMATED SOLUTION FROM CASTROL O MONITOR THE STATE OF THE COOLANT IN REAL TIME The article presents SmartControl
system – an automated solution
developed by Castrol
for monitoring the state of coolant
in real time, enabling to regulate
the parameters of water-miscible coolant.
THE ROLE OF CUTTING SPEED AND CUTTING WEDGE RADIUS IN FINE MACHINING EFFICIENCY OF HARD-PROCESSED MATERIALS. PART 2 The article considers scientific and technical approaches to the problem of determining
the cutting speed during machining of the working surfaces of machine parts and products with a unified tool on CNC lathes. It compares the optimum cutting temperatures obtained during turning of steels with the temperatures of their structural phase α–γ transformations. It is shown that the law of constancy of the optimum cutting temperature ensures the maximum tool life, the highest machining accuracy at the optimum cutting speed, both for structural and hard materials.
MODERN METHODS OF DIAGNOSTICS OF COMPLEX TECHNICAL SYSTEMS IN DIGITAL PRODUCTION The article considers the methods of equipment diagnostics based on the actual condition, such as vibration diagnostics, evaluation of the accuracy and consistency of the operation of drives. It presents the results of effectiveness calculations of these methods.
