IMAGINARY OBSERVATIONS & RESULTS

I’m going to be frank about this project about Engineering Methods; I really didn’t understand what it is you want me to do. I’ve tried so many things, I’ve read different articles and engineering manuals and nothing helps due to the fact I haven’t seen the procedure of what you’re trying to make us improve. Every Time Measurement Method or any other needs it to be visual, by that I mean a video taken of the procedure. Like myself since I have not worked on machinery before, I don’t know where to start or even imagine how to do these activities you’ve laid upon us. So here is my project of what I’ve understood along these couple of weeks.

Every system has been developed by industry for a similar purpose; each is a collection of time estimates for individual human motions in a specific work environment. Examples of these motions often include walking in a straight line, gripping an object with one hand, or bending at the waist to pick up a heavy object.

PMTSs generally fall into two categories: detailed and condensed tables. Detailed systems “provide subdivisions of body-member motions,” while condensed tables encompass times for more general combinations of body motions. One of the original detailed PMTSs is MTM-1. To develop a time estimate with MTM-1, the observer would watch an operator, and match each small movement the person makes to one of the body motions defined in MTM-1. Each movement on that list has a specific number of Time Measured Units (TMUs) assigned to it by its developers. MTM-1 is a procedure for analyzing any manual operation or method by breaking out the basic motions required to perform it and assigning to each a predetermined standard time based on its nature and the conditions under which it is made. Reach is the most common or basic MTM-1 motion. Other motions include the following:

Move. The predominant purpose is to transport an object to a destination.

Turn. The hand is turned or rotated about the long axis of the forearm.

Position. Motion is employed to align, orient, and/or engage one object with another.

Grasp. The main purpose is to secure sufficient control of one or more objects with the fingers or the hand.

Release. The operator relinquishes control of an object.

Disengage. Contact between two objects is broken.

Eye times. The eyes direct hand or body motions.

Body motions. Motions are made by the entire body, not just the hands, fingers, or arms.

IMAGINARY OBSERVATIONS & RESULTS

The total distance traveled during these multiple tasks is 87 meters. Which make no sense to me at all. I recommend to move all stations a bit closer in the lab in order to reduce the distance in which will help the time cycle to accomplish a batch. Within the process, there’s about 35 meters of distance between movements to apply, recharge, and take off of materials from press and such.

The total time consumed is 67 minutes, which is what I believe is expected due the fact the process layout is way confusing and the press and test labs are too far apart.

Recommendation:

Process to approve a batch needs to get modified in several ways I think. First is; try to move the press, the flow test and other test within the lab. That way the time taken by traveling to each station is reduced at least by 8 minutes. Second; try to reduce movements and waiting times in process. During the “cooking time” instead of cutting cookies, you should be preparing the viscosity meter then you start cutting the rubber. When you displace the samples you should check what your free hand is doing, if it’s free you can reduce that displacing time by getting two samples at a time or even recharge the press.

MTM ANALYSIS

I took the analysis to another different context, because I’ve never worked in such process nor have I worked in machinery I had to get help from my older brother. Placed all the movements of the whole process to see how many TMU’s it gave on the first study.

TOTAL TMU is of 270.8 (min/units)

By removing the unnecessary displacements and distance to travel station to station the TMU’s where reduced by 40%

Total TMU’s Study #2 is 180.2 (min/units)

I used this methodology:

REACH (R)

It’s the basic element used when the predominant purpose is to move the hand to a destination or a general situation. This element has the type variables, distance and the case. It is represented by [m] R [i] [k] [m] where [m] represents the type, [d] and the distance [k] the case.

Type [m] Definition

I hand is not moving at the beginning or at the end of the element. Example: R45B

II Hand is moving at the beginning or end of the element. Example: mR45B or R45Bm

III The hand is in motion at the beginning and end of the element. Example: mR45Bm

Case [k] Definition

To achieve an isolated object is always located in the same place. You have no control is needed to achieve it, for example, the tip of our nose.

B is reaching an isolated object whose situation varies from cycle to cycle slightly, eg a pen we left on the table. A light control is needed.

C is achieving mixed with other, where one has to do a search and selection object.

D is reaching a delicate object, very small or taken with caution by dangerous driving.

E is even hand out indefinite place to prepare the next move or clear the work area.

CATCH (G) GET

It is the basic element used when the predominant purpose is to ensure sufficient control of one or more objects with their fingers or hand to allow the execution of the next staple. This element has as variables the case. It is represented by G [k] where [k] represents the case.

Case [k] Definition

1 A solitary objects that can easily catch.

B -very small or thin objects
