Abstract

   Automatic Slotting Cutter Re-grinding Machine generally used to provide the teeth on the cutter which is used in the diamond collate industry. Thus this cutter's teeth may wear out as per operation done in the series. This may cause stop the production big way. To avoid this we have to regrind the cutter. After that we can use it. So to change this whole scenario we have introduce some of the changes in the machine which helps us to inspect the cutter before it wear out so we can cut down the teeth with the help of spur gear. So this helps us to increase the production of slot producing on die about 5000 to 6000 per cutter.     

Objectives

As our project is on IDP project, Re-Grinding Machine made by New Yogeshwar Diamond Collet Industry. This machine is used to produce teeth on the cutter and cutter is used to make slot on the Die, Which is used in the diamond industry. Thus as during this operation, if the teeth are wear out completely, We have to regrind the whole cutter. This machine produces the slot on 2500 ' 3000 die per cutter by manually operation. We are going to make arrangement & set up in machine which operates automatically instead of manually & only need a one supervisor for inspection the machine.

Introduction

Our Project 'Provide Automation to Slotting Cutter Re-Grinding Machine' is introduce that we are going to improvement in Manual Machine which is invented by New Yogeshwar Diamond Collet Industries. We will use Electric motor and some other components by which we can run a Slider automatically. And by using automation of slider, Cam follower and Ratchet gear will operate and a continuous Rotation of cutter spindle can handle.

In our Project, we use camera to match to teeth thus as the teeth wear out from cutter. We are informing immediately, thus we can insert the teeth to teeth matching and thus we can introduce proper teeth on the machine. That are done with the teeth to teeth matching produced of the cutter and grinding wheel.

      In this Machine we can make spur gear automatically by 'Cam Pin' & 'Ratchet Gear' and 'Camera Monitoring attachment'.

Knowledge Acquisition for Manual Re-grinding Machine

3.1 Various Parts of Manual Machine

  [Fig. No.: 3.1]

3.1.1 Construction:

         There are various machine parts which are used to construct the whole machine. Before introducing new parts, we have mainly eleven parts in the machine. After the change in the machine we have included three new parts to the machine for the more comfort as well as the whole automatic system in the machine. Here the detailed construction of each part is mentioned with the neat sketch.

3.1.2 Body:

      The body of the system is made from the cast iron where the whole construction is set on that. The cast iron used in body as it has fantastic property to absorb the vibration in the system. Thus it is very useful to absorb the vibrations which take place during the operation in the system.

3.1.3 Wheel Head:

                          

         [Fig. no.: 3.2]

          

       

        Wheel head is another important part of this automatic cutter regrinding machine. Here with the help of wheel head, cutter gives the required feed on teeth to teeth matching.

3.1.4   Dial Indicator:

                   

                                                                                [Fig. no.: 3.3]

Dial indicator is attached to the grinding wheel and cutter. Thus it shows whether the tooth to teeth matching has been done in between cutter and grinding wheel or not?

3.1.5   Grinding Wheel:

[Fig.: 3.4]

         It is another pretty important part of this machine. It is used to produce the teeth on the cutter as it wears out. Thus with the help of this cutter we can again starts the procedure to produce the slots on the die.

3.1.6   Power Transmission with Jockey pulley & Flat Belt :

[Fig.: 3.5]

        Here the shaft is used to transmit power in between the electric motor and the grinding wheel with help of belt drive transmission system. Also the jokey pulley is used to produce the require amount of rpm (rotation per minute) of the grinding wheel according to its requirements.

3.1.7    Slider:

                                                                     [fig.: 3.6]

    Slider is used in this machine produce the reciprocating motion in the shaft, which is later converted in to the rotary motion of the grinding wheel. This is operated manually in the old machine. While as we introduce the electric motor and the gear box.  It will run automatically.

3.1.8   Spur Gear:

[Fig.: 3.7]

        Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with the teeth projecting radially, and although they are not straight-sided in form (they are usually of special form to achieve constant drive ratio, mainly involutes, the edge of each tooth is straight and aligned parallel to the axis of rotation. These gears can be meshed together correctly only if they are fitted to parallel shafts.

          Here spur gear is mainly used to set the cutter's teeth distance (pitch). And also we this we can measure the no of teeth on the cutter with the help of spur gear. If the diameter of the cutter reduces the lesser teeth pin will be selected as per required according teeth on the cutter.

3.2 Features of Manual machine

' The cutter is used to make slots on the die which is used in the diamond industry. Thus as during this operation if the teethes are wear out completely, we have to regrind the whole cutter. In this machine teethes are made with slide of the slider with the help of dividing pin and spur gear.

' In this machine slide run manually and also spur gear manually operate.

' In the old machine as the cutter wear out completely than we have to regrind it with help of grinding wheel to used it again

' The old machine waste of cutter metal 2.0 To 2.5 mm.

' The old machine produces the slots on 2500-3000 die per cutter.

Knowledge Acquisition for Automatic Re-grinding Machine

4.1 Various Parts of Automatic Machine

4.1.1 Rat-Chet Gear:

    

[Fig.: 5.1]

     A ratchet is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. Though something of a misnomer, "ratchet" is also often used to refer to ratcheting socket wrenches, a common tool with a ratcheting handle.

4.1.2 Cam & Pin :

        When the teeth are moving in the unrestricted direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the opposite (backward) direction, however, the pawl will catch against the steeply sloped edge of the first tooth it encounters, thereby locking it against the tooth and preventing any further motion in that direction.

            Here in our machine with the help of these three devices, the spur gear will be works as automatic system.

       [Fig.: 5.2 A]

     [Fig.: 5.2 B]

   

[Fig.: 5.3]

4.1.3 Jockey Pulley :

[ fig.: 5.4]

' Jockey pulley is idler pulley and is used to increase the angle of contact in open belt drive.

' It is mounted near the smaller pulley of the two pulleys and is placed on the slack side of the belt as shown in figure.

' It increases angle of contact lead to increased power transmission capacity of drive.

4.1.4   Camera Monitoring System:

                                                           

[Fig.: .5.5]

            In the old machine as the cutter wear out completely than we have to regrind it with help of grinding wheel to used it again while as we insert the camera monitoring system in the machine it will tell us whenever the wear starts in the cutter, so with this we can improve our production big way. Also it will tell us whether teethes are matched or not?

4.2 Features of Automatic Machine

' In our machine with the help of these three devices pin, ratchet gear, cam the spur gear will be works as automatic system.

' while as we insert the camera monitoring system in the machine it will tell us whenever the wear starts in the cutter, so with this we can improve our production big way.

' The new machines save of cutter metal 2.0 To 2.5 mm.

' Teethes are done with the tooth to teeth matching procedure of the cutter and grinding wheel It gives slots on 9000-10000 die per cutter.

Cost Estimation

7.1    INTRODUCTION COST ESTIMATION DEATIL

- A project never completed without proper estimating aningd costing. The selling price of the final product is evaluated by analyzing the various cost parameters of project in from of manpower, machine, material and other requirement of factory. While going to various operations on the basis of above parameters total capital cost of the project is evaluated. All the parameters combine make total cost.

- On the basis of the principal of cost structure direct labour, direct material. And direct expenses are workout together it terms as 'PRIME COST'. Then we add to it, the overheads of the factory, which together are terms as 'PRODUCTION COST'   

- From this we can calculate the selling expenses of the machine and workout the overheads involved in selling Packing and forwarding etc. Much through we may like to have good share of profit. Initially 12% to 15% profit should be sufficient. Adding selling overhead and small profit margin to the production cost is called 'SELLING COST'

- Now, adding sales tax and other taxes to selling price is called 'TOTAL SELLING PRICE'

- Finally, add dealer discount in the total selling cost, we will get the 'CATALOUGE PRICE'.

7.2    AIM OF COSTING

The important aim & object of are as follow.

- To determine the cost of each article.

- To determine the cost of each article operation to keep central over workers wages.

- To provide information to ascertain the selling price of product.

- To supply information for detection of waste.

- It helps in reducing the total cost of manufacturing.

7.3    MATERIAL

A. Direct Material: -

- Material which is processed for the final product & become a part of the product is direct material & cost of these is 'direct material cost'.

B. Indirect Material:-

- Material which does not part of the final product but it is must for use for processing the direct material called 'indirect material cost'.

7.4    LABOUR

A. Direct Labour:-

- He worker who has performed the work on different material either manually or by a machine is called direct labour.

B. Indirect Labour:-

- It supervises the activity of direct labour.

7.5    EXPENSES

A. Direct Expenses:-

- The Expires which can be directly charged on a particular product is called 'direct expenses'.

B. Indirect Expenses:-

- The expenses which cannot be directly or conveniently charged on a particular product are called 'indirect expenses'.

Conclusion & Scope for Future Work

8.1    Conclusion:

The project work on 'AUTOMATION IN MANUAL CUTTER RE-GRINDING MACHINE' was like learning new things every day. Here I learn that how to improve an efficiency of this cutting machine, precise execution of work, and many virtues about work and engineering principles. I have realized how much care should be taken to make a brand of product in the international market. The most important thing I got to know from here is how quality of product being executed. I heartily thank to all staff members and managers for guiding me.

8.2    Scope for Future Work :

  

      An Automatic Cutter Re-Grinding Machine will capable to save a Cutter Material by which The Die Manufacturing Industries can save Half Expense of cutter. Because, A cutter is Re-Grinding 3 times in Manual Machine but in Automatic Machine it will Re-Grind 6 times. The saving will save as bellow calculation:

     Cutter Slot Production on 1 Machine (2 Head) : 600 die/day  

     Industry has 5 Machine                                            : 600''5 = 30,000 die/day

     No. of Die can Slot per Cutter which

                                     Re-Grinded by Manual M/C    : 3000 dies

     No. of Cutter required per day                                : 30000/3000 = 10 Cutter

                                    

                                            Cost of one Cutter : 100 ' 110 Rs.

                          There for, Cost of 10 Cutter : 100''10 = 1000 Rs./Day

     No. of Die can Slot per Cutter which

                               Re-Grinded by Automatic M/C    : 6000 dies

     No. of Cutter required per day                                : 30000/6000 = 5 Cutter
