The process computer is constructed from components similar to those used in a microcomputer system, with the difference that these components are considerably more powerful because of their processing speed and memory capacity. The supporting operating systems are also more powerful, meaning that many control tasks can be processed in parallel. For this reason, the process computer is used in places where it is necessary to solve extensive and complicated automatic control tasks. In such cases, it has the responsibility of controlling a complete process (such as a power station), which is made of a large number of subprocesses. Many smaller control systems, which operate peripherally, are often subordinated to a process computer. In such cases, the process computer assumes the role of a coordinating master computer.

Numerical control systems are the most widely used control in machine tools. A blank or preworked workpiece is machined by NC machine tools in accordance with specifications given in a technical drawing and other processing data. Two-, three-, or multiple-axis machines may be used, depending on the shape of the workpiece and the processing technology. A two-axis machine tool might be an NC lathe, for example. A milling machine is an example of a three-axis machine tool. In NC machines, sensors and actuators are connected to the processor by the manufacturer. The operator or programmer needs to know the operational principle and the interplay between the controller and machine. Figure 9.10 illustrates the location of holes to be drilled in a workpiece. The skilled machinist needs to know the material from which the workpiece has been made so that suitable drills and feed values can be selected for machining. A drilling machine is equipped with a work table which is adjustable in two directions. The adjustment is

The manufacturing procedure for a machine tool application is as follows: 1. The table is moved up to the reference point. The reference point values are imparted to the computer. The value zero is read from both scales. The drill is located above the reference point. 2. The workpiece is placed on the work table in the precise position required and clamped. 3. The workpiece zero point is determined; a reference edge from which all dimensions are measured is also determined. The drill is positioned at this point. The workpiece zero point can be imagined as the origin of a rectangular system of coordinates: the y axis is in one direction of motion of the table, the x axis is in the other. Similarly, the dimensions in the drawing are referred to this point. Thus, it is easy to move the work table to each point in turn where holes need to be drilled. Modifications can be carried out if required. 4. Machining is commenced; the working sequence should be described in detail. This description can completely replace the technical drawing. Any operator must be able to carry out the working cycle using this exact description.

9.6.2 The Machining Program
The machining program is described in terms of sequences: 1. Clamp drill 1. 2. Set X to 10 and Y to 15. 3. Drill at cutting speed 2. 4. Set X to 95. 5. Drill at cutting speed 2. 6. Unclamp drill 1, clamp drill 2. 7. Set Y to 45. 8. Drill at cutting speed 1. 9. Set X to 10. 10. Drill at cutting speed 1. 11. Remove workpiece. The positioning data, cutting tool information, and the required cutting speed must be identified to accomplish any machining operation. Usually, the technological data such as speed and feed are included in the tool data sheet. Tool number, speed, feed, and direction of rotation together form a unit. The feed speed has been omitted in the preceding program; this decision has been left to the operator. If the process is to proceed automatically at a later date, this information will have to be added. The positioning data is always referenced from the origin of the coordinates. In this case, this is always the point of intersection of the reference lines for the dimensioning of the drawing. The positional information was therefore given in absolute form and can be programmed in absolute dimensions. The information can also be provided relative to the current position, which is entered as the x value, and a new value added for the next position. This is called incremental positioning data. The incremental positioning data may be expressed as follows: 1. Set X + 10, Y + 15. 2. Set X + 80. 3. Set Y + 30. 4. Set X 80. Choice of the most suitable method often depends on the dimensioning of an engineering drawing. Sometimes incremental and absolute specifications of positional data are mixed. Then, obviously, it is necessary to describe the type of data in question.
