It is also useful for educational purposes, especially in practical work or curricula and continuing education programs. 9-32 Target Groups p • Industrial and trade mechanics • Tool & Die makers • Machinists • Millwrights • Draftspersons • Technical Instructors • Apprentices in above trade areas • Practitioners in trades and industry • Mechanical Engineering students 33- 56 3 Technical drawing TD 57 - 114 Notes for the user The contents of this book include tables and formulae in eight chapters, including Tables of Contents, Subject Index and Standards Index. The tables contain the most important guidelines, designs, types, dimensions and standard values for their subject areas. Units are not specified in the legends for the formulae if several units are possible. However, the calculation examples for each formula use those units normally applied in practice. Designation examples, which are included for all standard parts, materials and drawing designations, are highlighted by a red arrow(= ). The Table of Contents in the front of the book is expanded further at the beginning of each chapter in form of a partial Table of Contents. The Subject Index at the end of the book (pages 417-428) is extensive. The Standards Index (pages 407-416) lists all the current standards and regulations cited in the book. In many cases previous standards are also listed to ease the transition from older, more familiar standards to new ones. We have thoroughly revised the 2nd edition of the "Mechanical and Metal Trades Handbook" in line with the 44th edition of the German version "Tabellenbuch Metall". The section dealing with PAL programming of CNC machine tools was updated (to the state of 2008) and considerably enhanced. 4 Material science MS 115-200 5 Machine elements ME 201 - 272 6 Production Engineering PE 273-344 7 Automation and Information Technology 345- 406 A 8 International material comparison chart.

of uniformity of material and non-material objects, such as components, calculation methods, process flows and services for the benefit of the general public. Standards term Example Explanation Standard DIN 7157 A standard is the published result of standardization, e.g. the selection of certain fits in DIN 7157. Part DIN 30910-2 The part of a standard associat ed w ith other parts w ith the same main number. DIN 30910-2 for example describes sintered materials for filters, while Part 3 and 4 describe sintered materials for bearings and formed parts. Supplement DIN 743 Suppl. 1 A supplement contains information for a standard, however no additional specifications. The supplement DIN 743 Suppl. 1, for example, contains application examples of load capacity calculations for shafts and axles described in DIN 743. Draft EDIN 6316 (2007-02) A draft standard contains the preliminary finished results of a standardization; this version of the intended standard is made available to the public for comments. For example, the planned new version of DIN 6316 for goose-neck clamps has been available to the public since February 2007 as Draft E DIN 6316. Preliminary standard DIN V66304 (1991-12) A preliminary standard contains the results of standardization which are not released by DIN as a standard, because of certain provisos. DIN V 66304, for example, discusses a format for exchange of standard part data for computer-aided design. Issue date DIN 76-1 (2004-06) Date of publication which is made public in the DIN publication guide; this is the date at which time the standard becomes valid. DIN 76-1, which sets undercuts for metric ISO threads has been valid since June 2004 for example. Types of Standards and Regulations (selection) Type Abbreviation Explanation Purpose and contents International Standards (ISO standards) ISO International Organization for Standardization, Geneva (0 and S are reversed in the abbreviation) Simplifies the international exchange of goods and services, as well as cooperation in scientific, technical and economic areas.

T he clamping forces prevent the slipping o f the screwed parts or loosening of the bolts and nuts. In practice a loss of c lamping force can still occur due to t he following causes: 100 % 90 BO • Loosening of the screw joint caused by high surface contact pressures which initiate plastic deformation (so-called settling) and reduce the preload of the screw joint. Remedy: As little seperation as possible, m inimal surface roughness, use of high-strength bolts (large preload). , mecroencapsu at hesive: optimal 70 t .. 60 "O 0 ~ 50 Unscrewing of the screw joint: For joints dynamically loaded tran sverse to the bolt axis a fully self-actuated unscrewing can occur.

DIN EN ISO 9001 1 ) Requirements of a quality management system This international standard applies to organizations in any industry or business sector regardless of products offered. It establishes requirements for a QM system, based on fundamentals outlined in ISO 9000, if an organization: must demonstrate capability to offer product s w hich fulfill both customer and regulatory requirements, strives t o improve customer satisfaction, including the process of continuous improvement of the system. Specified requirements can be used for: internal applications by organizations • certification purposes • contract purposes The standard is based on a process oriented evaluation, i.e. every activity o r sequence of activities which uses resources to convert input into results is regarded as a process. Requirements The organization must: recognize all necessary processes for the OM system and their use in the organization, establish the flows and interdependencies of these processes, establish criteria and methods for ensuring implementation and co ntrol of these processes, ensure availability of resources and information for these processes, monitor, measure and analyze these processes, t ake necessary actions for continuous improvement of these processes, fulfill documentation requirements for the QM system, and observe regulations for document control. 1 DIN EN ISO 9004 ) This standard also replaces previous standards 9002 and 9003. Guideline for assessing the overall performance, effectiveness and efficiency of quality management systems The goal of this standard is to improve the organization and t o improve the satisfaction of customers and other relevant parties. It is not intended for certification or contract purposes. Quality-related terms Quality Extent to which the characteristics of a product fulfill the requirements for that product. Requirement Specified or mandatory demands for characte ri stics of a unit, e.g. nominal values, tolerances, functional capability or safety. Customer satisfaction Customer's perception of degree to w hich its requirements have been fulfilled. Capability Suitability of an organization, system or process to provide a product that fulfills that product's quality requirements. Characteristic and conformity related t erms Quality characteristic Identifying attribute of a p roduct or p rocess, which is utilized in assessing quality based o n the specified quality requirem ent s. Quantitative (variable) charact eristics: discrete characteri stics (who le numbers), i.e. number of holes, piece count cont inuous characteristics (measured values). e.g. length, positio n, mass Qualitative charact eristics: o rdinal charact eristics (with ranking), e.g. light blue - blue - dark blue nominal characteristics (without ranking), e.g. good - bad, blue - yellow Identifying attribute of a product, a process or system relating to a requirement.

Quality assurance Perfo rming and generating required documentation for all activities relating to the QM system, with the goal of creating an atmosphere of trust, both in-house and wit h the customer, that quality requirements will be fulfi lled. Quality improvement Actions taken throughout the organization to increase p roduct quality. Quality manual Document describing the quality policy, quality goals and quality management system of an o rganization. 276 Production Engineering : 6.1 Quality management Quality planning, Quality control, Quality testing Quality planning Rule-of-ten (for costs) Costs required to eliminat e defects or costs resulting from def ects increase by about a factor of 10 from phase to phase in the product life cycle. 100 product planning process planning and development and production testing and customer Example: A t olerance error on a single part can be corrected d uring the design p hase w it h negligible increase of costs. If t he defect is first noticed in prod uction. much larger costs result. If t he defect leads to problems in assembly or has an adverse impact on the fu nct ionality of the finished product o r even leads to a recall, eno rmous costs are incurred.

Normal distribution in an inspection lot Parameters of the population are estimated using a sampling method based o n characteristic values from t he sample (confirmatory statistics). To d ifferent iate sampling characteristics clearly from parameters of the population, other designations are used. These estimated values are disting uished from the calculated process values for a 100% inspection (descriptive stati stics) by adding a • mark.

The intervention and w arning limits are determined by the process estimated value of a population or a preliminary run. Acceptance control charts are used to monitor a process in reference to set specification l imits (limit values). Control limits are calculated as tolerance limits for the location of the process mean and a tolerance range for process variance.

DIN ISO 2859-1 (2004-011 An attribute inspection is an acceptance sampling inspection in which the acceptability of the inspection lot is determined based on defective units or defects in individual sampling. The percentage of nonconforming units or the number of defects per hundred units of the lot identifies the quality level. The acceptable quality level is the quality level defined for continuously presented lots; it is a quality level that is specified by the customer in most cases.

This type of cost aocounting would be misleading. If machine costs are taken out of production overhead and converted t o hours the machine was utilized, this yields the machine hourly rate. Compilation of machine costs Machine costs are: • Calculated depreciation Linear loss of value over the service l ife of the machine relative to replacement cost Energy costs Costs incurred by electricity, natural gas, steam or gasoline consumption • Calculated interest Average interest for capital invested for the machine Maintenance costs Costs for repairs and regular service • Other types of costs Costs for tool wear, insurance premiums, disposal of coolants and lubricants etc. • Occupancy costs Cost s incurred by floor and traffic space of the machine Machine running time, Machine hourly rates TRr Tr Tsr TsM according to VDI Directive 3258 Machine running time machine running time in hours/period total theoretical machine time in hours/period down times, e.g. work free days, work interruptions etc., usually in% of Tr times for service and maintenance, usually in% of Tr I TRT = h - TsT - TsM I Machine hourly rates sum of machine costs per period (usually per year) machine costs per hour; machine hourly rate CMhr machine fixed costs per year; e.g . depreciation Ct C.,/hr machine variable costs per hour; e.g. electrical consumption c, CM CMhr = - + Cv/ hr TRT Calculation of machine hourly rate (example) Tool machine: Procurement value$ 160 000.00 Power consumption 8 kW Occupancy costs $/m2 10.00 x mo nth Additional maintenance $/hr 5.00 Service life 10 years Cost per kWh $ 0.15 Space req. 15 m2 Normal utilization TRr = 1200 hr/year (100%) Assumed interest rate 8% Base charge $/month 20.00 Maintenance $/year 8 000.00 Actual utilization 80% What would be the machine hourly rate for normal utilization and 80% utilization?

The identification marking is intended to indicat e possible hazards and help t o prevent accidents and damage to health. Requirements concerning identification marking Identification marking must be clearly visible and longlasting. Identification can be established by painting, lettering (e.g. via self-adhesive foil strips) or signs. Particularly operation-critical and hazardous places should be marked (e.g. beginning and end of branch pipes, wall penetrations, linings). Marking must be repeated at least every 10 m of pipe length. Indication of the group and supplemental color (see table below). Indication of the flow direction by means of an arrow. • Indication of the conveyed substance by specifying the name (e.g. water) or the chemical formula (e. g.

It propagates in gaseous, liquid and solid bodies. Frequency Number of oscillations per second. Unit: 1 Hertz = 1 Hz = 1/s. Pitch increases w it h frequency. Frequency range of human hearing: 16 Hz- 20.000 Hz. Sound level Measure of the sound st rength (sound energy). Noise Undesirable, annoying o r painful sound waves; damage depends on strengt h, duration, frequency and regularity of exposure. For a noise level of 85 dB (A) and higher there is danger of permanent hearing loss. Decibel (dBi Standardized unit for sound level. dB(AI Since the h uman ear perceives tones of d ifferent heights (frequencies) to have different st rengths when t hey are actually at the same sound levels, noise must be appropriat ely dampened with filters for certain frequencies. Frequency weighting curve w ith Filter A compensates for this and indicat es the subjective auditory impression. A difference of 3 dB (A) corresponds approximately to a doubling (or halving) of the sound int ensity.

DIN 19226-1 to -5 ( 1994-02) Open loop control Closed loop control For open loop control the output variable, such as the temperature in a hardening furnace, is influenced by the input variable, such as the current in the heating coil. The output variable does not have an effect on t he input variable. Open loop control has an open action flow. For closed loop control the controlled variable, such as t he actual temp. in an annealing furnace, is continuously monitored and com pared to the target temp. (reference variable) and, if there are deviations, adjusted to the reference input variable. Closed loop control has a closed action flow.

PD-controllers are created when a P controller and a D element are connected in parallel. The D part changes the output variable at a rate proportional t o the rate of change of the input variable. The P part changes the output variable so that it is proportional to the input variable itself. PD-controllers act quickly. PID-<:Ontrollers Proportional integral derivative controllers PIO-controllers are created by connecting P, I and D-controllers in parallel. Initially the D part reacts with a large change to the control signal, afterwards this change is reduced to approximately the magnitude of the P element, and finally the effect of the I element causes the response to rise linearly. 11 Symbol as per DIN 19227-2 JI Signal curve at controlled system input 21 Block representation as per DIN 19226-2 41 Signal curve at controlled system output 349 Automation: 7.1 Basic terminology Discontinuous and digital controllers Switching (discontinuous) controllers cf.

When the cylinder is in its end position (B1 l and a bushing is available 164), the cylinder eX1ends in fast motion. The sensor B2 switches to feed mode. As soon as the bushing is forced in (B3) the cylinder retracts in fast motion. - Start step Start cycle (S1) and cylinder in basic position (B1) and bushing available (B4) Cylinder A 1 exiends in fast motion Cylinder A 1 extended (B2) Cylinder A 1 in feed mode Cylinder A 1 extended (63) Cylinder A 1 retracts in fast motion Cylinder Al retracted (B1) Symbol Examples Explanation Explanation Closed cycle (step chain) Steps This action is only valid as Continuous action t i as the corresponding !Cylinder A 1 retracts in fast motion ! long step is active.

English: specification language for function charts of sequential controls Automation: 7.3 Function charts and Function diagrams 359 Sequential chart A sequential chart consists of a series of steps placed one after another. Steps and transitions alternate. - Start step e.g. system "ON" Start-up push button Sl Pump motor ON Tank FULL Agitator motor ON 15s delay time OPEN drain valve 1. Sequential charts enforce a step structure developed from top to bottom. 2. Within the sequence, only one step can be active at a time. 3. The start step describes the initial condition of the system. 4. After execution of the last step and release of the transition, a feedback loop returns the system to the start step. Tank empty Transistions The transition is com- posed of • a dash and • a text describing the Agitator motor ON transition Transitions can be represented by: • text statements • Boolean algebra (equation) • graphical symbols 15s delay time 1. Step 3 is active, i. e. the agitator motor is ON. 2. If the condition for the release of the transition (the agitator runs for 15 sec.) is satisfied, step 4 is set. 3. Step 4 resets step 3, i.e. the ON signal for the agitator motor is no longer OPEN drain valve active. The motor is shut down. 4. The drain valve opens. Sequence selection (alternative branch) Sequence branch: The sequence occurs if step 5 is set a) branching to step 6 if the condition for the release A sequence branches to several sequences starting at a single or several steps. A difference is made between: of transition •e• is satis• tied, (e= 1) or • sequence branch • sequence junction b) branching to step 8 if the condition for the release of transition "f" is satisfied (f= 1). Example: sequence branch Simultaneous sequences (parallel branch) A sequence branches to multiple sequences that are simultaneously activated but run independently of each other. The next individual step is carried out only after all branches are processed. _Q_ A sequence from step 2 t o steps 22, 24 et c. only occurs if, a) step 2 is set 00 b) the condi tion for the release of the common transition "a" is satisfied (a=1). 0 and 360 Automation: 7.3 Function charts and Function diagrams Function charts for sequential controls, Examples er 0IN EN 6084812002 121 Example: Lifting device Workpieces are lifted by a lifting cylinder and pushed onto a roller conveyor by a transfer cylinder. Actuating the main valve and start button S1 causes the lifting cylinder 1A1 to extend, lifting the workpiece and activating the l imit switch 1B2 in the end position. This causes transfer cylinder 2A1 to extend, pushing the workpiece onto the roller conveyor and activating limit switch 2B2.
