What is the production line cycle and what is the production cycle?

The "cycle time" of a process is the time between two successive completion of the same product (or two servings, or two batches of products). In other words, it refers to the average time it takes to complete a product. Cycle time is usually simply used to define the unit output time of a specific process or step in a process.

If the product must be made in batches, the cycle time refers to the time between two batches of products. In process design, if a process is given in advance how many outputs it must produce per day (or other unit of time), the first thing to consider is the tempo of the process. In the design of a machining line, the cycle time is a very important factor in the design.

The balance of the production cycle is important. The formula of the production cycle is t=60t n formula, where t is the production beat, t is the basic working hours of one year, and it is generally stipulated that the working hours of one shift are 2360h years and the working hours of two shifts are 4650h years; is the complexity coefficient, which is generally taken as; n is the annual production program of the workpiece processed by the production line. The main classifications of mechanical processing production lines are:

Single product fixed beat production line, single product non-fixed beat production line, group product adjustable production line, flexible manufacturing production line.

For example, the hourly output of 1 production line is 100There are 10 operational positions. First, calculate the time of a single machine 10 100 = that is, the processing time of a single machine, and then divide it into 3600 seconds in 1 hour, 3600 * single time, that is, the time required for each machine is 360 seconds.

Then 360 seconds, 10 people = 36 seconds, is the production cycle time of this line. Considering the fatigue strength of normal people, our production will generally hit 80%.

The margin is 36* seconds.

Does beat production treat people as machines, what is beat production, and why should we adopt the beat production model. In fact, the rational use of cycle time can help you streamline and achieve rapid production.

The word "production beat" is a German word for conductor, which is used to adjust the rhythm of the performance, t t beat time, the production cycle time obtained according to the customer's demand and the factory's available time, which is the bottleneck station time and the production cycle that can meet the customer's needs.

Production cycle, also known as customer demand cycle and production distance time, refers to the ratio of the total effective production time to the quantity of customer demand within a certain length of time, and is the market necessary time for customers to demand a product.

On the production line, whether the cycle times are equal.

Hello dear! We'll be happy to answer for you. On the production line, whether the cycle times are equal Answer:

The time of a single piece operation is equal to takt or an integer multiple of takt. The balance of the production line is to average the whole process of production, and adjust the operating load to make the technical rolling means and methods as close as possible between the acres of the Li Sen industry. The purpose is to eliminate the efficiency loss and overproduction of unbalanced operations, production line balance is a great science, production line balance is directly related to the normal use of the production line.

The line balancing guide mainly includes the relevant definition of line balancing, the meaning of line balancing, the calculation of process balancing ratio, and the principles and methods of improving line balancing.

The formula for calculating the cycle time of the production line refers to the calculation of the number of times the production line can be completed per hour according to various factors on the production line. The calculation method is generally as follows: production line cycle time = 3600 (single piece production time + single piece production preparation time).

Among them, 3600 is to convert the unit of time from seconds to hours, the production time of a single piece refers to the production time of each product from the beginning to the end, including production, testing, debugging and other times, and the preparation time of a single piece of production refers to the preparation time required before starting to produce the next product, such as adjusting the machine, changing the raw materials and so on.

It should be noted that the formula for calculating the cycle time of the production line is only a simple calculation method, and many other factors need to be taken into account in the actual application process, such as the technical level of the personnel on the production line, the maintenance of the equipment, the quality of raw materials, etc., which will have an impact on the actual cycle time of the production line.

Therefore, in order to calculate the cycle time of the production line more accurately, it is necessary to take into account various factors, conduct actual research and data analysis. Through the observation, recording and analysis of the actual operation of the production line, more accurate production line beat data can be obtained, which can be used as the basis to improve the production efficiency of the production line, optimize the production process, and improve product quality and production efficiency.

In short, the production line cycle calculation formula is a very important tool in production line management, but it is necessary to comprehensively consider various factors in combination with the actual situation to obtain more accurate production line cycle data, and on this basis, continuously optimize the production process and improve production efficiency. <>

Step 1: Identify the factors influencing the cycle time. Such as: personnel skills, personnel turnover rate.

Material packaging method, distribution route frequency, stability of process technology, operation performance of equipment, plan changes, management level, etc. It is necessary to consider every factor that affects the stability of the company, analyze the degree of impact, and improve it.

Step 2: Evaluate the flow of funds at different beats.

speed, the number of inventory turnovers, combined with the improvement plan, the design of scientific beats.

Step 3: Improve the work carried out to achieve the design beat to the beat volatility.

The evaluation process should be dynamically managed according to the state.

Step 4: Under the guidance of the beat of the design, the dust of the manuscript, the machine and the material flow continuously, and the value is maximized. For example, a car in 60s, all supporting resources and management methods are carried out in accordance with this rhythm.

According to research, the optimal cycle time range for rapid manufacturing enterprises is 15s to 180s, which is more suitable for improvement, management, and resource allocation.

Step 5: The beat should be redesigned due to changes, and the rationality should be judged by the only evaluation criterion for efficiency. Short, medium and long-term planning, orderly progress of defense and respect.

The beat is not changed at will, let alone simply set and executed, but needs to continue to run in, adjust with my brother, and find the optimal rhythm. It's a long-term battle, and standard hours are not measured.

Just do the math!

Process cycle balance refers to a management method that optimizes the production efficiency of the entire production line by adjusting the production cycle of each process in the production process. Specifically, it is to analyze and optimize the production time, production quantity, material and other factors of each process on the production line, so that the production rhythm of each process is relatively balanced, so as to avoid affecting the production efficiency of the entire production line because the production speed of a process is too slow.

The takt time of the equipment is the dust and disturbance time of the equipment during the production process, and the production time is the total time required to complete a product, including non-running time such as various adjustments and preparations. The cycle time of the equipment is usually shorter than the production time due to:

1.The takt time of the equipment is the running time, while the production time is the entire production cycle including downtime and adjustment time, so the production time will be longer than the cycle time.

2.In the production process, the equipment can achieve continuous production with high efficiency, but there will be some stagnation or adjustment time in the production process, which will increase the production time.

Therefore, the cycle time of the equipment is usually shorter than the production time, which does not mean that the speed of the equipment determines the production efficiency. In fact, proper production planning and production process management are the key to maintaining production efficiency and reducing production costs.

The cycle time of a machine refers to the time it takes for a machine to complete a product, while the production time refers to the time it takes to complete an entire production batch. Typically, the cycle time of the equipment is shorter than the production time, because the following situations may occur in the production process:

First of all, there may be a long waiting time in the production process of non-combustion, such as waiting for raw materials, waiting for workers to be in place, etc. These waiting times are counted in the production time, but do not affect the cycle time of the machine.

Secondly, there may be limb failures or downtime for maintenance during the production process, which will also be counted in the production time, but will also not affect the cycle time of the equipment.

Finally, there may be adjustments and coordination during the production process, such as machine changeovers, overhauls and cleaning, which are also counted in the production time, but also do not affect the cycle time of the machine.

Therefore, in order to ensure production efficiency, the cycle time of the equipment is usually designed to be shorter than the production time to ensure that the equipment can complete the production task smoothly and leave enough time for other parts of the production process.

Because the equipment shed regrets that the chain is based on the operator to allocate the time to produce products faster. If the cycle time is too long, it leads to reduced productivity; If the cycle time is too short, it will also lead to the omission of the work that should be done, which will affect the quality of the product. Therefore, the right machine cycle time is an important factor in increasing productivity.
