6.4 Slides and slideways. The slides and slideways of a machined tool locate and guide members which move relative to each other, usually changing the position of the tool relative to the workpiece.

Definition. Cutting is manufacturing by removal of material (DIN 8580; CIRP Dictionary 2004). Particles of material, the chips, are mechanically removed from the raw material or from an unfinished part by cutting edges of a tool. Figure 1 shows some cutting processes (DIN 8589; CIRP Dictionary 2004).

The first machine tools that were made actually date back to 1200 B.C.E. What were they? In line with the needs of the time, the first two tools ever recorded were the bow drill and the bow lathe.

Three basic types of guide ways can support linear motion between machine tool components: rolling-element, hydrostatic and plain sliding ways.

while it is straight line for lathe, drilling, boring machines, etc. Requirements of guideways are : (a) Guideway should have high rigidity. (b) The surface of guideways must have greater accuracy and surface finish. (c) Guideways should have high accuracy of travel.

: a way along which something slides.

A slideway is used to control the direction or line of action of the translational movement of the table or carriage on which the tools or work are held. The alignment of the slideways to each other is therefore critical. Critical dimensions depend on the accuracy and consistency of the slideways.

Explanation: In CNC systems multiple microprocessors and programmable logic controllers work in parallel for simultaneous servo position and velocity control of several axes of a machine for contour cutting as well as monitoring of the cutting process and the machine tool.

Explanation: Milling machine is a machine tool that removes the metal as the work is fed against a rotating multipoint cutter. Here, in milling machine multi point cutter should be used. 2. In milling machine, cutter rotates at high speed and removes metal at very high speed.

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

Indexing is an operation of dividing a periphery of a cylindrical workpiece into equal number of divisions by the help of index crank and index plate. Because the operator of the machine may want to rotate the part to an arbitrary angle indexing plates are used to ensure the part is accurately positioned.

Angular displacement is expressed in minutes then the terms of the index crank can be calculated by dividing the angle by 540. If it is expressed in seconds then it is divided by 32400. When a result is a whole number, the index crank is rotated through the full calculated number.

There are various facilities for utilizing the data which enhance the basic recorded material; namely the selection of segments, the addition of annotations, and the post-processing and analysis of data.

Indexing is broadly referred to as an indicator or measure of something. In the financial markets, indexing can be used as a statistical measure for tracking economic data, a methodology for grouping a specific market segment, or an investment management strategy for passive investments.

Direct indexing is the name we coined years ago for tax-loss harvesting within an index. We called it direct indexing because you directly own all the stocks that comprise an index in your brokerage account (instead of owning an index fund) and then perform tax-loss harvesting on those individual stocks.

Step 1: Firstly, you require a trading and demat account to invest in a Nifty index fund. If you don’t already have one, you can open these accounts by visiting the website of your favorite stockbroker. Step 2: Follow the procedure to open a trading and demat account as listed by your stockbroker.

Indexing Strategies: Definition Indexing is – very simply – an investment strategy, which attempts to mimic the performance of a market index. An index is a “yardstick”, and a market index is a group or “basket” or portfolio of securities selected to represent and reflect the market as a whole.

Index investing is a passive investment strategy that seeks to replicate the returns of a benchmark index. Indexing offers greater diversification, as well as lower expenses and fees, than actively managed strategies.

There are approximately 5,000 U.S. indexes. The three most widely followed indexes in the U.S. are the S&P 500, Dow Jones Industrial Average, and Nasdaq Composite. The Wilshire 5000 includes all the stocks from the U.S. stock market.

There are two types of Indexes in SQL Server: Clustered Index. Non-Clustered Index.

Investing in index mutual funds and ETFs gets a lot of positive press, and rightly so. Index funds, at their best, offer a low-cost way for investors to track popular stock and bond market indexes. In many cases index funds outperform the majority of actively managed mutual funds.

No. You won’t get rich off index funds. Not unless you make a lot of money at your job. Index funds are a great vehicle for long term growth over the course of a working persons life that ensure he’ll probably have a comfortable but not lavish retirement.

The report’s research shows Vanguard has a better after-tax return and is more tax-efficient than Fidelity. In the funds sampled, Fidelity had a lower expense ratio than Vanguard. They also found Vanguard funds are more diversified./span>
