ensure your personal safety,as well as to prevent damage to property.The notices referring to your personal safety are highlighted in the manual by a safety alert symbol,notices referring only to property damage have no safety alert symbol.These notices shown below are graded according to the degree of danger.DANGER DANGER indicates that death or severe personal injury willwill result if proper precautions are not taken.WARNING WARNING indicates that death or severe personal injury maymay result if proper precautions are not taken.CAUTION CAUTION with a safety alert symbol,indicates that minor personal injury can result if proper precautions are not taken.CAUTION CAUTION without a safety alert symbol,indicates that property damage can result if proper precautions are not taken.NOTICE NOTICE indicates that an unintended result or situation can occur if the corresponding information is not taken into account.If more than one degree of danger is present,the warning notice representing the highest degree of danger will be used.A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.Qualified

Fundamentals and Job planning Programming Manual Fundamentals and Job planning Programming Manual The description of the NC programming is divided into two manuals:1.FundamentalsFundamentals This Fundamentals Programming Manual is intended for use by skilled machine operators with the appropriate expertise in drilling,milling and turning operations.Simple programming examples are used to explain the commands and statements which are also defined according to DIN 66025.2.Job planningJob planning The Programming Manual Job planning is intended for use by technicians with in-depth,comprehensive programming knowledge.By virtue of a special programming language,the SINUMERIK control enables the user to program complex workpiece programs(e.g.for free-form surfaces,channel coordination,.)and makes programming of complicated operations easy for technologists.Availability of the described NC language elements Availability of the described NC language elements All NC language elements described in the manual are available for the SINUMERIK 840D sl.The availability regarding SINUMERIK 828D can be found in column 828D of the List of statements(Page 483).Preface
