ElectroChemical Grinding, or ECG, is a variation of ECM (ElectroChemical Machining) that combines electrolytic activity with the physical removal of material by means of charged grinding wheels. ElectroChemical Grinding (ECG) can produce burr free and stress free parts without heat or other metallurgical damage caused by mechanical grinding, eliminating the need for secondary machining .
estimator encounters when wo rking on technical calculations for specific technologies. V ery often tenders were not complete and not detailed enough, and the time required for a good technical calculation is getting every day shorter. It is not easy to present exact technical figures and quantities for the equipment or operations not fully

Lathe Turning Time Calculator. Calculate the required time for turning lathe operations from the given length of job, feed rate per revolution and revolution of the job per minute using this Lathe turning time calculator.
Machining is manufacturing process that involves removing materials using cutting tools for getting rid of the unwanted materials from some workpiece and converting it into the shape you desire. A large piece of stock is used for cutting the workpiece. The large stock might be in any shape such as solid bar, flat sheet, beam or even hollow tubes.
machining. Nickel alloys are classified into different categories according to their relative machining behaviour as shown in Table I. A different set of machining conditions is applicable to each category, and the first step for successful machining is for the programmer/machinist to identify the applicable category for the alloy to be machined.

Grinding laws. with W as grinding work in kJ/kg, c as grinding coefficient, dA as grain size of the source material and dE as grain size of the ground material. A reliable value for the grain sizes dA and dE is d80. This value signifies that 80% (mass) of the solid matter has a smaller grain size.
UNIT 2 GRINDING Grinding Structure Introduction Objectives ... used when workpiece material is not very hard and grinding time is also small. Normally ... capability of grinding machine. Grinding wheels are named as soft, hard or medium hard wheels depending on their grade. Abrasives of hard grinding wheels get blunt quickly so these are
May 12, 2009· Handheld angle grinders have long been used extensively in the metal fabrication and welding industries; however, they also now are being used more frequently in the mechanical contracting, autobody, masonry, and stoneworking industries for grinding, .
Quality of machined surfaces and its integrity are strongly dependent on tool wear, which consequently depends on the tool life or machining time. Therefore, prediction of the machining time of the cutting tool during machining processes is very important in order to obtain high precision parts and to reduce manual fit operations and production cost.
KipwareCYC produces accurate machining cycle time estimates for both manual and cnc equipment including lathes, machining centers, wireedm and other machine shop equipment. Accurate cycle time estimates are the key to producing accurate cost estimates and quotations.

ESTIMATION OF MACHINING TIME. INTRODUCTION: Machining time: It is the time for which the machine works on the component that is from the time when the tool touches the work to when the tool leaves the component after completion of the operations. Terms used in the study of machining time: 1. Length of cut Length of cut = approach length + length of work piece to be machined + over travel 2.
Nov 13, 2015· The formula used in computing the rate is: "Machine hour Rate is calculated by dividing the cost to be apportioned or absorbed by the number of hours for which a machine or machines are operated or expected to be operated" Machine Hour Rate = Total Factory Overheads(budgeted or actual) Total Machine Hours (estimated or actual) EXAMPLE: If factory overhead is Rs 3, 00,000 and total .
