CNC Turning
What is CNC Turning Machining ?
Turning, a process associated with lathe machining, is a component of mechanical manipulation. In lathe machining, turning tools are primarily employed to shape the rotating workpiece. Lathes can also accommodate drills, reamers, taps, dies, and knurling tools to achieve various types of processings.
Primarily, lathes are vital in shaping shafts, discs, sleeves, and other components with revolving surfaces, making them an indispensable tool in machinery manufacturing and repair factories. The operating mechanism involves the turning of the workpiece, while the turning tool moves along a linear or curvilinear path on the plane.
Primarily, turning is performed on a lathe to shape the internal and external cylindrical surfaces, end surfaces, conical surfaces, forming surfaces, and threads of the workpiece.
Turning Process:
- Select and determine the CNC turning content of the parts;
- Analyze the CNC turning machining process on the part drawings;
- Selection and adjustment design of tools and fixtures;
- Design of procedures and steps;
- calculation and optimization of machining trajectory;
- Compilation, verification and modification of CNC turning programs;
- First piece trial processing and handling of on-site problems;
- Preparation of technical documents for CNC machining; in short, there are many CNC machining processes, some of which are similar to ordinary machine tool processing.
Process analysis forms the preliminary groundwork for CNC turning. The reasonableness and efficiency of this process profoundly influence the creation of the program, machine tool efficiency, and the precision of the crafted parts.
To craft a practical and effective machining program, programmers must thoroughly grasp the questionably principle, performance traits, and structural facets of CNC lathes. They should be fluent in operating language, programming formats, grasp the intricacies of workpiece processing technology, determine appropriate cutting quantities, and precisely select the tool and workpiece clamping technique. Therefore, it’s essential that we adhere to general processing principles and merge these with the unique attributes of CNC lathes, in order to conduct a meticulous and detailed analysis of the CNC turning process.
Mainly, this analysis encompasses evaluating the processing requisites and rationality of components according to schematics, pinpointing the method to secure the workpiece on the CNC lathe, and ascertaining the processing order of each surface. Additionally, the tool’s feed route, and the choice of tool, fixture, and cutting quantity also come under this extensive inspection.
