Increasing the Machining Productivity of the Firing Pin Body Part Through Automated Tool Selection

The research addresses the issue of increasing the machining productivity of the “Firing Pin Body” part of the aerosol smoke system AEK-902 “Khmara”. The Ukrainian Armed Forces actively use the “Khmara” system to create dense smoke screens, including during the evacuation of personnel from the battlefield. Ensuring the operational readiness of the “Khmara” system is a relevant issue. The “firing pin body” part is important to the smoke grenade launch system. Automated tool selection is proposed to enhance the machining productivity through optimal tool and cutting parameters. A comparison of solutions from three leading cutting tool manufacturers −Walter, Sandvik Coromant, and Iscar − was conducted. The selection was made using software from the manufacturers: Walter “GPS”, Sandvik Coromant “ToolGuide”, and Iscar “ToolAdvisor”. The comparison was based on machining productivity and tool life. For machining the part, the following technical solutions were proposed: for operation 010, use the following tools: through cutter DSSNL2020K12 with SNMG120416-PR4335 insert, through cutter CP-25BL-2020-12 with CP-B1216D-M7 4425 insert, through cutter DCLNL 2525M 19 with CNMG 190612-PR 4425 insert, drill 462.1-1020-051A1-XM-X2BM, boring tool A08H-SCLCL06 with CCMT 060208-UM 1125 insert, drive tool drill 862.1-2500-225A1-GM X2BM, drive tool tap T300-PM100JA-M3 P1PM, cutoff tool QD-NN2F33-25A with QD-NF-0250-0003-CH 1225 insert. For operation 020, use: through cutter DSSNL 2020K 12 with SNMG 120416-PR 4425 insert, boring tool A08H-SCLCL06 with CCMT 060208-UM 1125 insert, boring tool A16PR-SSKCL09 with SCMT 09T312-PR 4425 insert, and drive tool drill 462.1-0650-020A1-XM-X2BM. The proposed set of cutting tools enables full and efficient machining of the firing pin body part.
