PDE modelling of lattice structure in an optimial way.

 Coming soon.

Lattice structure will be designed and optimized for a certain parameter in a pre-known algorithm. 

Proposed Methodlogy of the work. 

Lathe milling attachement

 

Summary of the Project

This work starts with problem identification and giving a solution to it. The solution has mechanical forecasting to a problem and proper designing of components. The paper aims at designing and simulation milling attachment on lathe. It is intended to design a mechanism that enables milling operation namely end mill, side mill, and gear cutting on a lathe. We attempted to make a versatile operation for a medium-duty lathe. The attachment can carry out an indexing mechanism and vise-like milling machine with back and forth movement of lathe carriage. This mounted on a toolpost, where we fix the workpiece and a mandrel or a chuck mechanism is designed to hold the cutting tool. This mandrel or chuck mechanism is attached to the headstock spindle, which is the main source for the motion of the cutting tool. In the design process a major designing process of frames, jaws, gears, shafts, screws, handle, indexing plate, and bearing selection has been taken place. Full design of this enables us to machine slots with different orientations, splines and light-duty gears namely spur gear and the helical gear.

Problem formulation in the internship trained 

Lathe is suitable for operations like turning, boring, facing, tapering, thread cutting, knurling, and parting operation. However, it is not suitable for operations like keyway cutting, side milling, and gear cutting. In the time of the internship program, we face different problems and we gave solutions especially, on machine maintenance. In the company, there is a milling machine problem. It may be maintained, but no longer used. On our own, we try a lot to maintain but we cannot fix it. Absent of spare parts and being century makes it difficult. Thus, we attempt to design an attachment on the lathe in order to solve this problem. Comparatively milling machine cost is high. So light duty industries exposed to extra loss for simple milling operations.   Therefore, it is better to use attachments at a low cost. This will reduce the investment for medium and small-scale industries, subsequently reduce the manufacturing cost of gears and blocks in addition to solve a problem in our company. In a conventional lathe as soon as the machine is switched on, the workpiece fixed to the chuck rotates. This is a major limitation of the conventional lathe keeping in view of the present project.

The operation in simulation can be seen as follow;
