Machining Operations and Part Geometry Each machining operation produces a characteristic part geometry due to two factors: 1. Relative motions between the tool and the workpart •Generating –part geometry is determined by the feed trajectory of the cutting tool 2. Shape of the cutting tool •Forming –part geometry is created by the

Economics of Machining Process and Operations. 1. Optimizing Cutting Parameters for Minimum Cost: The total cost of a part can be written in the form –. R = R 1 + R 2 + R 3 + R 4 + R 5,… (4.77) Where R is the total cost / piece, R 1 is the material cost / piece, R 2 is the set-up and idle time cost / piece, R 3 is the machining cost ...

When the grinding department is slack and everyone else is slammed it may pay to go old school by opening up the pre-grind tolerance and finish requirements accepting that the job spends more time being ground but less time on machining operations freeing machinery up …

PARAMETERS OF GRINDING OPERATION Major process parameters which are most commonly used in grinding process are machining speed, feed rate and depth of cut. 9.1. Cutting Speed It is the comparative peripheral angular velocity of the abrasive grinding wheel with respect to the work material.

The tool path in the case of surface machining with complex shapes (fig. 6) and also when machining pockets is a key issue of the technological operation. Milling is characterized by the necessity of dynamic changes of machining parameters during machining. CAM software plays a very important role in this machining method.

For any machining or material removal operation, three relative motions between workpiece and cutting tool are indispensably necessary, which, in fact, are the primary cutting parameters. The simultaneous action of all three parameters causes material …

This paper studies how to optimize the different machining parameters in glass grinding operation on CNC machine seeking for best surface roughness. These parameters include the spindle speed, feed rate, depth of cut, lubrication mode, tool type, tool diameter and tool wear.

machining Operations. In turning, a cutting tool with a single cutting edge is used to remove material from a rotating workpiece to generate a cylindrical shape.The primary motion is provided by rotating the workpiece, and the feed motion is achieved by moving the cutting tool slowly in a direction parallel to the axis of rotation of the workpiece.

The grinding performance is significantly affected by, the important parameters in the grinding machine like feed, depth of cut, work piece material. The effect of these parameters on the grinding machine is measured in terms of the surface finish produced on the work piece during subsequent grinding operation.

Because the decision of the machining parameters for grinding operation is influenced by many factors, such as machine tool, cutting tool, the material of the work-piece, the quality of the work-piece to be achieved, the allowed period and the cost to achieve the work-piece, and so on. In a word, the new method is necessary when to rapidly and ...

operation during grinding. Each and every moment of machining process was observed carefully by providing input parameters in sequential manner. Figure 2 shows the grinding of a specimen when it is fitted on chuck subjected to high speed grinding wheel which is assisted with coolant system to meet better accuracy and finish.

effectively machine all materials whether they are electrically conductive or insulator. For an effective cutting operation, the following parameters need to be carefully considered: The machining tool must be selected to be highly wear resistant, such as high-carbon steels.

In machining, three process parameters are (i) cutting speed or cutting velocity, (ii) feed rate and (iii) depth of cut. More details about these parameters are elaborated in the following sections. Process Parameter – 1: Cutting velocity (Vc) Cutting velocity is the most important cutting parameter that provides necessary cutting motion (CM).
