Grinding machines employ a rotating abrasive wheel that removes material from the workpiece through abrasion. The grinding wheel is composed of abrasive …
The abrasion technique removes extra material from a work piece during the grinding process. Grinding is usually used as a final step in the machining process. Abrasion occurs in the grinding process due to relative motion between the abrasive material and the work piece. Electrical motors are used in industrial applications for this …
The primary motion is the main motion provided by a machine tool to cause relative motion between the tool and workpiece. Usually, the primary motion absorbs most of the total power required to perform a machining operation. ... or the secondary motion, is a motion that may be provided to the tool or workpiece by a …
of workpiece. Therefore, in general, two kinds of relative motion must be provided by a machine tool. These motions are called primary motion and feed motion and are defined as follows. The primary motion is the main motion provided by a machine tool to cause rela - tive motion between the tool and workpiece. Usually, the primary motion absorbs
Secondary Motions of Loom: There are two types of secondary motion of loom. They are: Take-up motion; Let-off motion; A. Take Up Motion The take up motion is to draw a fabric to the cloth roller regularly and withdraws the cloth from the weaving area at a regular or constant rate so as to give the required pick-spacing (in picks/inch or …
The main objectives of the grinding process include obtaining a desired particle size distribution in the fina l product without metal or other possible contamination, increasing the throughput of ...
In the grinding process, abrasion takes place between abrasive material and workpiece by relative motion. In industrial uses, this relative motion is employed with the help of an electrical motor. This is generally electrically operated but, in some cases, other modes of operation can be used. ... This is also the main parameter that affects ...
In the grinding process, the grinding force, energy, power, and temperature are directly related to the material removal rate. In this article, the chip model in Grinding …
Fig. 4 shows the gear grinding process where two synchronous motions represented by red and blue arrows are illustrated as well. The combination of the red arrows can be called positive motion and the combination of the blue arrows can be called negative motion. The positive and negative motions will be considered in the next sections.
Specification of grinding wheel: Grinding wheel is the main component of the grinding machine. It is responsible for the whole machining process. The proper selection of grinding wheel is very important and the selection of the grinding wheel depends on various factors such as a material of the work piece, finishing requirements etc.
Grinding is a manufacturing process which significantly contributes in producing high precision and durable components required in numerous applications …
Grinding and polishing are exercises in contrast: Often, the executing designs machine unusually large surfaces to particularly tight tolerances. Here we outline motion mechanisms...
Oscillating grinding is a high-efficiency machining method for crankshaft pin journal, and motion model is one of the important foundations of oscillating grinding, which heavily affects the ...
Primary service usually refers to the main service provided, often the primary reason for the service's existence. For example, primary care is the main doctor that treats your health, usually a general practitioner or internist. Secondary service, on the other hand, refers to services that are supplementary or complementary to the primary ...
Let - off motion is a secondary loom motion. The main objectives of let - off motion are to release the warp after beating of every inserted pick and to regulate the warp tension. When the fabric weaving remains continue, the take- up motion pulls the woven fabric continuously to maintain the fell of the cloth position.
Auxiliary motion includes the tool's pre and post-contact travel relative to the workpiece. The primary cutting motion is powered on most machine tools, while feed and depth of cut motions are given manually. On manually operated machine tools, auxiliary motions are also performed manually by the operator.
This chapter provides practical data for the selection of grinding and finishing operations applied to these industrial sectors and includes a guide on the selection of grinding …

Grinding is a machining method that removes small amounts of material from both flat surfaces and cylindrical shapes. Surface grinders reciprocate the work on a table while feeding it into the grinding wheel. The depth to which the wheel cuts usually falls between 0.00025 and 0.001 in.
The Surface grinding Surface grinding is widespread in industrial applications and is used for machining flat work piece surfaces. In general usage, "surface grinding" often only refers to the process of horizontal-spindle peripheral surface grinding. This peripheral surface grinding with the grinding wheels' circumferential surface as the effective …

Complexity and Specificity: The more complex or specific the secondary process, the longer it might take. For example, a simple deburring process might add minimal time, while multi-step surface treatments could extend the lead time. Batch Processing: Some secondary processes, especially those related to finishing, might be done in batches. If ...
