CNC program precision prototype precision copper bushings

What is the scene

  1. The scene includes two factors: “present” and “field”. CNC program precision prototype precision copper bushings
  2. “Now” means now, the meaning of the present, emphasizing the timeliness.
  3. “Field” means place, place, emphasizing regionality.
  4. The combination of “present” and “field” means a specific area given a certain time.
  5. For manufacturing enterprises, the site is the production workshop. CNC program precision prototype precision copper bushings.

Go into the scene

  1. The “three busy” phenomena on site:
    Busy: On the surface, everyone seems busy, but in fact, they are doing redundant things, or what they are doing is ineffective. (fuss)
    Blind: Because they are too busy, people always do things mechanically, without working direction, and their efficiency is not high.
    Confusion: Long-term blind work has caused people to be numb and confused. They don’t know what they are doing all day long, and everything they do is confused.
  2. The most important thing on site is the output:
    Analyze the current situation–find bottlenecks—take measures–solve problems–increase production (display capabilities)
  3. On-site functions: output products. CNC program precision prototype precision copper bushings
  4. Core elements of on-site management: 4M1E
    Personnel (Man): quantity, position, skills, qualifications, etc.
    Machine: inspection, acceptance, care, maintenance, calibration
    Material: delivery date, quality, cost
    Method: production process, technology, operating technology, operating standards
    Environment: 5S, safe working environment

The golden rule of on-site management

  1. When a problem (abnormality) occurs, go to the scene first.
  2. Examine the phenomenon (characteristics of the genbutsu (relevant objects)).
  3. Take temporary measures on the spot.
  4. Uncover the real cause and eliminate it.
  5. Standardize to prevent recurrence. CNC program precision prototype precision copper bushings

6 basic principles of production activities

  1. The post-project is the customer
    The quality of the work is determined by the post-project evaluation
    Do not accept failure, do not produce failure, do not pass failure
  2. Bida production plan
    Annual plan, monthly plan, CNC program precision prototype precision copper bushings
    Daily and hourly production according to plan——Guarantee of production plan
  3. Completely eliminate waste
    Waste refers to: things that can be done without doing, things that can be done without
  4. Standardization of work
    There are standard work books and work benchmark books, but they are not standardized.
    Standardization is to make regulations, comply with and improve the regulations, and continuously improve–obey—re-improving activities can be called standardization.
  5. Value-added work
    The purpose of management is to seek greater added value (profit)
    On-site personnel must have an overall view, identify production bottlenecks, and adopt optimal countermeasures
  6. Actively respond to changes
    Basic requirements——Determine the basics of standard books and other tasks, and develop the habit of complying with them
    Observe first——gather intelligence beforehand and take next steps
    Master strength——Improve skills and expand strength, improve equipment utilization rate, etc. CNC program precision prototype precision copper bushings

Daily work on site

  1. On-site quality management
    How to ensure excellent quality on site? 5 principles to avoid mistakes:
    a. Cancel this job
    b. Don’t let others do it
    c. Make the work easier
    d. Check
    e. Reduce the impact
  2. On-site cost management
    The best way to reduce costs is to eliminate excessive resource consumption
    a. Improve quality: quality of work process, reasonable 5M
    b. Increase productivity to reduce costs: continuous improvement
    c. Reduce inventory: working capital, storage, transportation, quality hazards, new products
    d. Shorten the production line: reasonable production line workers
    e. Reduce machine downtime
    f. Reduce space
    g. The role of on-site in reducing total costs
  3. Delivery time:
    One of the main tasks of a manager
  4. Contents that should be mastered in actual on-site operations
    a. The rationality of the production operation plan, the production plan and actual difficulties, and the impact of plan adjustments
    b. Personnel status, employee skills, production shutdown caused by material shortage and equipment failure, countermeasures and treatment of defective products
    c. Whether the parts/tooling fixtures/production accessories are complete, whether the production is normal, and whether the working methods can be improved. CNC program precision prototype precision copper bushings

5.Basic methods on site
Go deep into the front line, keep information flowing, understand production capacity, pay attention to employee status, and conduct time/action research

  1. Precautions on site
    Institutionalization of exception handling, on-site education, explanations, clear job responsibilities, and fair evaluation of employees

Implementation methods of on-site management

  1. Key points of daily management
    a. Pay attention to all management projects
    Focus on quality today and equipment tomorrow?
    b. Decide on key management projects
    Principle: “Don’t cause abnormalities to the next project or customer”, determine key projects
    “To what extent it should be done”, setting the management level
    c. Habitualization of management
    Quantify and clarify some daily tasks and make management habitual
  2. How to carry out daily management
    P-D-C-A management cycle
    Such as operation management, the goal is to achieve the production plan and improve productivity.
    P (Plan): achieve production
    D (Implementation): Execution plan—job setting
    C (Check): Check the difference between target and actual performance
    A (action): Take countermeasures or improve. CNC program precision prototype precision copper bushings
  3. On-site management policy

a. The work slogan of the production department:
Don’t accept bad things, don’t create bad things, don’t pass on bad things!

b. Quality management policy:
Quality first, efficient and punctual, customer satisfaction, continuous improvement.

c. Production management policy:
Innovate technology and improve production processes; scientific management and strengthen operational harmony; tap potential and fully mobilize enthusiasm; pursue excellence and comprehensively improve production efficiency.

d. Management requirements:
A. The position responsibility system has been implemented as the basis and the responsibility contracting system for all employees has been implemented.
B: The task is dead. It must be executed if there are conditions. If there are no conditions, it must be executed even if conditions are created.
C: Whatever is decided is right. If you have any doubts, you can talk about it later.
D: Rewards and punishments must be clear, timely and in place. CNC program precision prototype precision copper bushings

  1. Autonomous management
    a. Work with the mentality of doing things for yourself.
    b. Take responsibility for yourself and make your own decisions if the standards are met.
    c. Do not shirk responsibility
    d. Complete work tasks based on self-centeredness

5.Three inspections
a. Its function is to realize the “three no’s”. (Don’t accept defects, don’t create defects, don’t pass on defects)

b. To achieve “double inspection”, we rely on independent management:
Inculcate the importance of implementing “double inspection”.
Occasional on-site inspections
When problems arise, it is emphasized that “double inspection” involves the responsibilities of both parties.

  1. Repair work
    a. Repair operations refer to corrective measures implemented for defective products.
    b. Make repairs, draw inferences from one instance and provide feedback to prevent recurrence.
    c. Working hard and working hard is not necessarily the best. CNC program precision prototype precision copper bushings
    d. Repairmen are the cradle of production department managers, especially team leaders.
    e. Management of repair products:
    Repaired products need to be re-inspected by the original inspection station
    Have repair items properly labeled
    If multiple repairs or major hidden dangers are discovered during repairs, they should be reported immediately
  2. Execution of work instructions
    a. The team leader should be familiar with the work instructions and teach the employees;
    b. It may not be the best method, but as a standard, operators must abide by it at all times.
    c. If you have a better method, you can propose modifications, which can only be implemented after the modifications are approved.
    d. “5 other methods”:
    tell him
    Do it for him
    Let him try it
    Confirm for him
    give him praise
  3. Grasp the main thread of the scene
    a. What is the main line of the scene? Production Plan
    All the people on site were surrounding it. is the focus.
    is the work goal
    It is the standard to measure the results of work. CNC program precision prototype precision copper bushings
    b.Daily production plan:
    The planned output is the task, and you will be held responsible if it is not completed.
    If you cannot complete the task, you must apply for overtime.
    It is the basis for producing daily reports.
    Once the production plan is released it is an order!
  4. Be aware of the output
    a. Output is the only important goal of the production department.
    b. In order for production managers to know the output well, they need to master and control the speed of the production line.
    c. Factors that determine output:
    Production line operating speed
    Mechanical capabilities of machines, equipment
    Engineering and process stability
    Personnel’s working ability production preparation
    Production preparation is the entire process from the beginning of trial production to mass production of a new product. In order to ensure that the new product can be successfully trial-produced and mass-produced as planned, and to ensure product quality, relevant personnel training, instruction book formulation, and logistics adjustment are carried out. Preparatory activities for reaching and equipment (including tooling, measuring tools, and tools). CNC program precision prototype precision copper bushings

Production preparation in on-site management

  1. Production process and data preparation: flow charts, work instructions, drawings, QC standards, etc.
  2. Preparation of fixtures, tools, auxiliary materials, labor protection supplies, etc.
  3. Installation and debugging of equipment, instruments and tooling
  4. Personnel position arrangement and production capacity setting
  5. Pre-production training for on-site employees
  6. Discovery and feedback of abnormalities in materials, equipment, processes, and data

verify at the scene

  1. On-site configuration management table:
    Also called the production line configuration management table: its form is like a checklist, which allows managers to confirm the layout status of the site.
    Designate workstation personnel, tools and supplies, instruments, material placement areas, work methods, record sheets, etc.
  2. On-site equipment inspection.
    Timing, scope, responsible person, frequency, method, content, record, confirmation.

Management of daily homework reports

effect

  1. Tools for multiple project management such as delivery time, quality, safety, cost management, etc.;
  2. Facilitate the transmission of intelligence and exchange of information with superiors and other departments;
  3. Data used as cause tracking when various abnormalities or problems occur;
  4. Help managers grasp the actual situation on site.

common problem

  1. There is too much content and it is very time-consuming to record;
  2. There are too many things that require thinking, recalling, and judgment, which are very unusual, so forget it;
  3. You are unwilling to write and let others write for you;
  4. No one will guide you how to fill it out, so just fill it in casually; CNC program precision prototype precision copper bushings
  5. The work daily report is just collected as information, and the boss does not read it, so it is of no use.

Requirements for daily work reports

Design requirements
All necessary items are in place and the project is streamlined as much as possible
The order of projects must conform to actual work or logical habits
Reduce descriptions or numbers and use symbols or lines instead of entries
Use standard paper to avoid being too large or too small for easy archiving

What should be grasped
Is everyone’s daily work report accurate?
Are there any abnormalities in materials/work/products?
Operation efficiency
Whether it meets the plan
Production efficiency and equipment efficiency
Defective products and lost work hours
Is the current working hours and staffing allocation reasonable? CNC program precision prototype precision copper bushings
overall performance

Filling in the homework daily report

Fill in daily homework report

The function of the daily homework report needs to be explained to the relevant filling personnel;
The basic contents such as team name, operator name, product name, batch number, etc. are filled in by the on-site office staff, and then sent to the operator to fill in other matters to reduce the burden on the operator;
The production quantity and processing time are only known to the operator and should be filled in by the operator;
Develop the habit of confirming again after writing;
Managers should carefully review the daily operation reports, point out abnormal points in a timely manner and help solve problems to form a good interactive situation;
On-site personnel can grasp abnormal trends in operations based on daily reports and implement key guidance in response to such trends. CNC program precision prototype precision copper bushings
