Machining Toronto is further classified into three sub processes: turning, drilling and milling. There are other procedures that fall into the miscellaneous categories including planning, broaching, shaping and sawing.
This particular machine operation produces cylindrical parts. It can be basically defined as the machining of an external area while the work piece is rotating, using a single-point cutting tool and with the tool used for cutting being fed to the machine parallel to the axis of the work piece.
One type of turning is called the taper turning. This is somewhat the same with basic turning except that the cutter path is placed at an angle against the work axis. In contour turning, the cutter’s distance from the work axis is at a different angle in order to produce the desired output.
While the use of single point cutting tool is emphasized, this does not completely exclude the use of multiple tool set ups. Multiple tools are also being employed in turning. When this set up is used, every tool involved operates independently as an individual cutter.
There are three primary factors when it comes to basic turning process. These are the feed, speed and depth of the cut. There are also other important factors to be considered like the kind of material and the type of tool to be used. However, it is the speed, feed and depth that the operator has a control of.
When you say “speed” this refers to the work piece and the spindle. When revolutions per minute are dragged in the conversation, this will mean the rotating speed of the machine. The important figure that one has to learn in a turning operation is the surface speed. The surface speed is the speed at which the piece of material is moving past the tool used in cutting. Simply stated, this is the product of the circumference of the work piece multiplied by the rotating speed before the machinist starts to cut. Speed is expressed in terms of surface feet per minute.
Feed on the other hand refers to the cutting tool. Feed is the rate at which the cutting object advances on its cutting path. On fast paced lathes, the feed rate is related directly to the speed of the spindle which is expressed in inches per revolution or ipr. This figure is usually less than one inch and is commonly expressed as a decimal amount.
The depth of cut refers to the thickness of the material that is being removed from the work piece. In other words, this is the distance from the surface which is uncut to the cut surface. This figure is expressed in inches.
