TECHNOLOGICAL FEATURES OF REALIZATION OF PLUNGER MILLING OPERATIONS

Milling technological operations are one of the most productive and widespread methods of metalworking. From the point of view of providing the blank with the desired configuration, thesetechnological operations represent the most universal method of processing. Technological operations of plunger milling are now becoming more and more widespread. Plunger milling is used precisely when the use of traditional methods is impossible due to excessive vibrations. Performing technological operations of plunger milling is fundamentally different from performing technological operations of traditional milling. The article contains recommendations that must be followed when performing technologicaloperations of plunger milling. The purpose of the article is to determine the possibility of using any CAM-system to ensure high-quality execution of technological operations of plunger milling. To do this, it is proposed to check whether the CAM-system supports two requirements. The article provides a list of the most common CAM-systems, indicating whether a given software module supports plunger milling. The article proposes a scheme for the implementation of the trajectory of the plunger cutter for the use of any CAM-system in order to ensure the high-quality execution of technological operations of plunger milling. This proposed scheme consists of four main stages. The first stage of the proposed scheme consists of the formation of an array ofholes within the contour of the cavity or other surface being processed. The essence of the second stage of the proposed scheme is to determine the value of the allowance for finishing (depending on the complexity of placing the holes in the contour of the cavity, it is possible to increase the allowance for processing). The third stage of the proposed scheme consists in developing, based on the array of holes that was formed in the first stage, the software code for inserting a cutter into each of the holes in accordance with the coordinates that are specified (by analogy with the development of drilling cycles). The essence of the fourth stage of the proposed scheme is to manually program the removal of the plunger cutter from the walls of the cavity or other surface being processed
