The instructions and drawings give a step-by-step method of recommended installation procedures. Methods will vary among millwrights, but if you are not sure which is best, we suggest that you follow instructions in the manual. In addition to installation instructions, you will also find operating, maintenance and trouble shooting guides, as

• Most milling machines are equipped with power feed for one or more axes. Power feed is smoother than manual feed and, therefore, can produce a better surface finish. Power feed also reduces operator fatigue on long cuts. On some machines, the power feed is controlled by a forward reverse lever and a speed control knob.

Possible answers are: The method of difference, the method of agreement, the joint method of agreement and difference, the method of concomitant variation, the method of residues, and correlation. Indicate whether you think the argument is strong or weak.

Basically there are two methods of producing new surfaces, the tracing method and the generation method. In the tracing method the surface is obtained by direct tracing of the generatrices and when the surface produced is the envelope of the generatrics the process is known as generation.

NC words constitutes a complete NC instruction, known as block. The commonly used words are N, G, F, S, T, and M. The same is explained later on through examples. Hence the methods of part programming can be of two types depending upon the two techniques as below : (a) Manual part programming, and (b) Computer aided part programming.

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.

milling operations with the appropriate fixture. This type of lathe can handle workpieces up to 25 inches in diameter and up to 200 inches long. However, the general size is about a 15-inch swing with 36 to 48 inches between centers. Many tool room lathes are used for special tool and die production due to the high accuracy of the machine.

The knee and column type milling machine is the most commonly used machine in view of its flexibility and easier setup. The knee houses the feed mechanism and mounts the saddle and table. The table basically has the t-slots running along the x-axis for the purpose of work holding.

The first thing to calculate is the cutter start point called the "pivot" point. This can be calculated as follows. Pivot point = (part diameter - cutter diameter) ­÷ 2. Pivot point = (2.5" - 1.0") ÷ 2 = 0.750". The cutter begins to cut the thread when the cutter is in this position (X0.750, Y0). …

Manual Part Programming . In manual part programming, the programmer prepares the NC code using the lowlevel machine language previously described. The program is either written by hand on a fonn from which a punched tape or other storage media is subsequently coded, or it is entered directly into a computer equipped with NC part programming software, which writes the program onto the …

1.1. Machining by milling Deburring defined workpiece edges. Deburring completely machined parts (with clearly defined edges) is a well established process nowadays in most cases and is normally no longer questioned. This means, it is normal that the parts are of course deburred automatically on the CNC machine using a chamfer milling cutter.
