 Hello friends. Good afternoon. Today we are going to discuss about the recording techniques which are used in the method study. As you know select record examine develop define install and maintain are the major steps of the flow of the method study out of which we are going to study recording techniques in detail and recording techniques can be in the variety of forms it can be in the forms of graphs it can be in terms of charts tables it can be into graphs and so on and the recording techniques can also be on a timescale and those can also be without timescale today we are going to study one of the preliminary recording technique which is called as a flow process chart at the end of the session you will be able to draw and apply flow process chart during the method study part of it the contents of the today session will be we will have a small introduction the significance of a flow process chart what are the various symbols used for the flow process chart and how to draw the flow process chart what are the activities and the construction details of the flow process chart as you know the flow process chart is a process which a process chart setting out the sequence of the flow of a product or a procedure by recording all events under review using the appropriate process chart symbols there are variety of flow process charts the first one is metal type flow process chart which is indicating the flow of the material from one place to another place there is other type called as man type flow process chart which is indicating the movement of the person from various workstations to the end of the particular process and the third one which is called as equipment type flow process chart which which tracks on the movement of the equipment and how the equipment travels from one place to another place the significance of the importance of the flow process chart is it is a chart of a flow process chart is a chart of all activities involved in the process not usually used for the entire assemblies it is generally used for one component or generally for a single operator process chart summarizes the whole process start to end these are used to compare the existing and the proposal method we have to draw the flow process chart for the existing method we have to analyze the flow process chart reduce the unnecessary movements or unnecessary distance during the particular process again redraw the flow process chart and compare the flow process chart with the initial or start of the process and the proposed or the new method of the process where you will find that at the end of the proposed method we will be able to compare and we will be able to find out what is the possible saving in terms of distance and time or the moment of the operator of the equipment every detail is understood and the chart of the existing and proposed situation is drawn additional information on the operator sequence and a distance traveled for the for the particular process is also shown over here there are a variety of standardized process symbols which are used for while drawing the charts these symbols are the first one is operation which is indicated by a circle operation can be a it can be manual operation it can be a machine operation it indicates the main step in a process method or procedure usually the part material or product concerned is modified or changed during the operation next symbol is inspection it is indicated by a square it is inspection for the quality or check for the quantity it can be either a quality check or a quantity check quality check can be in terms of a variable measurement it can also be for a attribute measurement it can be in the form of yes no present absent okay not okay accepted not accepted go no go or it can be any value by a measuring instrument or it can just simply give a particular check for either a particular operation is accepted or not accepted the third symbol is transportation which is indicated by a arrow which is indicating the moment of the worker or the material from one place to the another place it can also indicate the equipment moment from place to place temporary storage or delay which is generally indicated by a capital D of English letter it indicates a delay in the sequence of events for example worker waiting between consecutive operations or any object later aside temporarily without a record until required generally in the variety of machine shops we'll observe that a particular job is waiting for a particular process because the machine is already overloaded or the machine is having a constraint as a result of that material is piled up near that machine and job is waiting for that particular operation therefore in such cases it is generally denoted as a temporary storage or sometimes for unforeseen circumstances like electricity failure or machine maintenance or operator absent there can be a delay for the particular process and therefore the job is only indicated as a D the job is lying there only for some moment of time as soon as a particular delay is removed either machine is having a maintenance which is cleared or electricity starts supply electric supply starts once again then probably the machine gets okay and then the job can be processed on that machine where the delay can be further eliminated the next symbol which is usual for the flow process chart is called as a permanent store which is generally indicated by a inverted triangle it indicates a controlled storage in which material is received into or issued from a store under some form of authorization or an item is retained for the reference purpose generally there are variety of stores in the organizations it can be a raw material storage it can be a finished storage or it can be a tool storage it can be a inspection storage and so on a job generally is taken from a raw material storage processed under variety of workstations and then finally given to the fg store generally called as finished wood stores where it is further moved for the shipping or dispatch in this storage activity either a raw material storage or temporary or the permanent storage in the fg storage is generally indicated by a permanent storage activity as such these are the five basic symbols which are used for drawing a process chart now there can be a other issues for example now you think of a particular combined activity where operation is going on along with the inspection and in such cases we are interested to show both the activities simultaneously when it is desired to show activities performed at the same time or by the same operator at the same workstation the symbol for those activities are combined as a operator is doing some operation at the same time is inspecting it also in this case the symbol can be combined with inspection and operation and it looks like this it is a circle which is drawn in a square you can have combination of variety of symbols depending upon the combination of the activities once we understand the variety of different charts of chart symbols now we will proceed for the example of each of these operations for example a process chart symbol circle is indicated and some examples are shown like a manual operation driving a note or a machine operation like drilling a hole or some a typing process and so on transportation it is a moment by the particular operator moment by a truck moment by the high store crane or a man moment from carrying out inventory from one place store it can be a messenger which is taking a message from one workstation to another stage there are some other examples of inspection a square which is indicating as inspection activity which is examine material for quality or quantity it can be the reading the gauge or of the boiler it is just showing a pressure or some particular indication or it can be examination of the print form of the information delays material in truck which is waiting for unloading is also indicated as a material in truck or floor indicating at this and storage variety of storage are shown over here this is a construction where the step by step procedure for the construction is given now we have to draw a procedure draw a chart by following all these steps of the construction once these understood you can the particular steps are understood you have to follow the base chart symbols and draw a flow process chart the flow process chart will look like this the flow process chart will be indicating the total summary when the process chart are being made regularly it is convenient to use in a printed or stainless sheet as showed in the figure thank you
