 Hello friends. Welcome to the session today. We are going to discuss about the recording the facts in method study. The session will tell us that what is the importance and type of recording techniques. You will be able to understand the importance as well as why the recording technique should be done, what are the various types of recording techniques. The content of session will be what are the basics of recording, what are the common symbols used in the recording techniques, what are the various types of process charts and diagrams, models and a small example of what are the example of a recording technique. Well, all of us know what is method study. Method study is finding out an alternative better method which will improve the productivity which will reduce the metal handling which can add value which can reduce the stress level of the operator which can reduce the scrap and so on. Once we decide to go for method study the first step becomes selection of a job and there are various considerations for selection of a job which we have studied in the earlier session and today the next step after the selection of the job we have to go for recording the facts about the job. How to record the facts and what are the various simple techniques for that we are going to study in this session today. After selection of the job the next step is all the facts has to be recorded. The success of the method study depends upon accuracy of the event or the fact which is recorded and at the same time which forms the basis for critical examination and development of a new method. The techniques can help us in recording events accurately and in this standard format. Techniques should be easily understood by all method analysts. Recording must be accurate. It must have clear and concise. It should be easily understandable by all especially by the workers. We can record the facts even with the help of an essay type note or we can just have a video or we can have a discussion, question answers. Anybody can have his own way of recording but that may not have any standardization. That may not have the repeatativeness. Therefore there have been standard procedure standard techniques which have been used in the recording. ASME has used some charts and diagrams and for all charts and diagrams there are some basic symbols which are used for recording. These basic symbols are the first one is operation which is a circle. The next is inspection. You can carry out inspection manually or on the machine. Wherever inspection is there the symbol usually is a rectangle. Transportation of material or a person or an equipment from one place to another place is represented by an arrow. The arrow head is moving towards the transportation and there are two types of storages. One is a temporary storage where the job may wait for the next operation or there may be some temporary storage or there may be some delay because of some issues at the shop maybe because of the machine breakdown or operator absenteeism or tooling problem or some other problem and there is a permanent storage which is generally called as the last stage of the operation. After the job is complete the job is handed over to the permanent storage. Recording can be done with the help of various charts and diagrams and models. The diagrams and charts are generally classified into two groups. The first one is which is not using a without timescale which is called as charts and diagrams without timescale. Those are the recording techniques used to record a process sequence series of events, orders or any other activity but do not depict in the event on the timescale where the timescale is not mentioned in such charts and diagrams. There is other category of the recording techniques which is with timescale. These are the recording techniques where the events in sequence are occurring on a timescale so that interaction of related events can be more easily studied. We need to note down time for each and every event and their interdependence and dependence on each of these. So there will be some jobs where we may not require time required. We are only interested in the emotion. We are interested in the sequence. We are interested in how the things are moving from one place to another place irrespective of or independent of the time. Whereas in case of some jobs where we want to interest, we are interested in studying the process time of a job or mental hand time required of the job or inspection of the job. In these cases, we are going to have the recording with the help of a timescale where a stopwatch can be used for recording the various events. Further, the charts can be classified into subgroups. The first one that is without timescale, there are charts and diagrams which is called as outline process chart or operation chart. Next one is flow process chart. There are three types amongst flow process chart, man type, material type and equipment type. Man type flow process chart will give the flow of the person where the job is moving from one place to another place. Material type flow process chart, the focus will be on the material movement rather than anything else. And the equipment type equipment is, for example, we are using some grain or some fixture or some attachment. In that case, our focus of study will be equipment where we are trying to find out equipment utilization and how to optimize the equipment utilization. In that case, flow process chart of equipment type can be of much more help. 200 process chart mainly used for small electronic items and their assemblies, where both the hands are used simultaneously for the processes. Travel chart which is mainly used for the metal handling movements and those will telling you about the metal handlings. Then charts which are falling into the group two that is which requires a timescale. These can be the first one more versatile, more important is multiple activity chart where it tries to combine the man machine activities on a timescale. And we are interested to find out utilization of the person or utilization of the machine or idleness or we want to schedule the machine or equipment so that the idleness of both can be minimized and this multiple activity chart on a timescale will help to record all these facts. Cmo chart it is a short form of simultaneous motion chart. So it is the motion economy is more considered over here. In this case, we are trying to find out motions along with the timescale of a particular job. There are some diagrams which are used on the recording area. The first diagram is a flow diagram where we are using a arrow or we are taking a picture of a particular situation and the flow diagram as in case of flow process chart diagram is give a diagrammatic representation of the entire operations, entire workstations, entire material movement, entire machine movement, equipment movement and so on depending upon the type. Again, flow diagrams are classified into three man type flow diagram, machine type and material type. Machine or equipment both can be used over here. The selection of the three will depend upon what is the focus of the particular study, what is the objective of the we want to utilize the man at the highest level, then we go for flow diagram of the man type. We are interested in studying out the equipment, then we go for equipment type of flow diagram. We are interested in optimizing the material movement and then naturally as a result of this material flow diagram will be used. Cycle graph and chrono cycle graph. This is a very interesting graph. It is a diagram actually, but generally called as a graph because it uses a photosensitive paper. When there was no technology available, today this particular cycle graph chrono cycle graph is generally irrelevant because we have got all latest modern technologies for recording including videos. In the absence of videos and cameras, these cycle graph and chrono cycle graph were developed where it was using a light source and a photosensitive paper. And as a result of that, the photosensitive paper used to record what is happening to the hand movements through a light source and the light source path was disturbed because of the movement of the hand operations and that was recorded on the graph paper. So that is why it is called as cycle graph or chrono cycle graph. There's a small difference between these two chrono cycle graph will use the direction of the movement where a cycle graph it is very difficult to predict what is the movement. It is from left to right or right to left is not easily visible in terms of cycle graph. Chrono cycle graph gives a peer shaped dots as a result of that it is easier to identify the direction in case of chrono cycle graph. String diagram as the name suggests it uses a small string for recording the moments generally used for metal handling areas of metal handling applications. String diagram very useful for the optimization of the metal handling solutions. Travel chart generally used for the mental movement from one place to another place where we are firing out a matrix from and to and then we are using some over techniques so that where the maximum mental movement is there and whether the machine movement is correct or the mental movement is correct or not or the whether it calls for any changes in the layout. For layout consideration generally we are using travel chart. Then models used are 2D and 3D modeling very simple models you can have a 2D 3D modeling and nowadays we are using some simulation techniques with the help of ultra modern techniques like videos and so on which will help us for recording with the help of models directly which gives the entire records and then with a slow diagram or a slow motion we try to just correlate the recordings. Here is a simple chart which is giving you the example of recording techniques where manufacturing or movement of material or movement of worker can be useful for which type political chart is used. Now we have to think of what is a nut bolt assembly whether it is an example of a 200 process chart whether the fact is correct or not whether both the hands are required or not you have to find out. The answer obviously is yes so nut and bolt assembly requires both hands as a result of this is a example of a 200 process chart. Well we have summarized what are the various charts and diagrams used for the method study. Thank you.
