Analysis of Dongguan CNC lathe parts and process analysis

1. Analysis of part processing process

(1) Set the workpiece coordinate system

According to the principle of rejuvenation, set the original point of the workpiece coordinate system on the intersection of the right end surface of the part and the rotary axis, as shown in the OP point in the figure, and set the coordinate position of the original point OP of the workpiece coordinate system through the G50 instruction (200,100 200,100 )

(2) Choose a tool

According to the processing requirements of the parts, the end surface, cylindrical, cone surface, arc surface, chamfering, and cut thread retractor and threads are required to process the parts of the parts.

The 1st knife, the outer circle left partial knife, the knife model is: CL-MTGNR-2020/R/1608 ISO30. Installed on the No. 1 knife.

No. 3 knife, thread car knife, and tool model: TL-LHTR-2020/R/60/1.5 ISO30. Installed on the No. 3 knife.

(3) Processing plan

Use the No. 1 outer circle to left the sword, first rough processing and then processing the end surface of the parts and the outer surface of the parts of the parts. Use No. 3 thread car knife to process thread.

(4) Determine the amount of cutting

Cutting depth: The cutting depth of the rough processing setting is 3mm, and the precision processing is 0.5mm.

Subdivy speed: According to the cutting performance of No. 45 steel, the cutting speed is set to 90m/min when the processing end surface and the outer surface of each section; the spindle speed is set to 250R/min when the thread is screw.

The above is the introduction and description of stainless steel lathe parts screw lathing metal CNC machining, I hope it can be helpful to you.
