OPERATING MACHINE OF BASIC NC/CNC BASIC COMPETENCE :CONDUCTING EARLY INSPECTION

Conducting early Inspectiona. Learning Objectives After following the learning activity student expected to be able to:Knowing early inspection procedureKnowing which part that need to be conducted early inspectionConducting early inspection according to procedure and standard job specifiedLEARNING ACTIVITY 3

CONGENIALITY OF EARLY INSPECTION 1. Congenality of early inspectionEarly inspection is a inspecting activity, checking, examining supply job condition, interconnected supply with the operation of machine of CNC, before machine of CNC run with program of CNC

THE EARLY INSPECTION OBJECTIVES2. The Early Inspection ObjectivesDetecting early things that can make trouble for the operation of machine of CNCPreventing the happening of mistake which can cause failure of process and productLessening possibility the happening of mistake because of negligence effect of job by operatorAs standard operation to give safety guarantee and security operation of machine

EARLY INSPECTION TARGETEarly Inspection TargetChuck position, chuck technique, and strength in chucking of job objectCutting tool position in the early pathPath or cutting trajectory

SUMMARYSummary 3Early inspection is a inspecting activity, checking, examining supply job condition, interconnected supply with the operation of machine of CNC, before machine of CNC run with program of CNC The Early Inspection Objectives : Detecting early things that can make trouble for the operation of machine of CNCPreventing the happening of mistake which can cause failure of process and product) Lessening possibility the happening of mistake because of negligence effect of job by operatorAs standard operation to give safety guarantee and security operation of machine

TASK 3

Do inspection early to chuck of work piece. Study datum installation of chucking plan picture plan. Is there any error of installation of work pieceDo task number (1), on chucking to other work pieceDo early inspection to cutter position in the early path. Study rule of distance which ought to pursuant to information at G 92. Measure cutter position, is there any error of cutter locationDo number (3), to early path position for other cutterDo cutter trajectory test to a CNC program. Perceive, is there any error on trajectory? If there is error, try to correct wrong part program and its result show to teacher

1. Early inspection is inspection:before program runnedpath before program runnedcondition of tools before CNC machine operated all answers are correct2. The target of early inspection is:prevent product failureprevent accidentearly detection on program errorAll answers are correct3. In operating CNC machine, early detection must be conducted a. every day b. the first program to be run c. all programs to be run d. all answers are correct FORMATIVE TEST

4. Early Inspection at grasping of work piece meant a. check condition and position of chucking b. check does work piece installed c. check work piece condition d. All answers are correctEarly checking to cutter position at early program meant to: a. check cutter motion is correct b. check cutter type, is correct c. check cutter distance what is according to rule check d. All Answer are correctFORMATIVE TEST

6. Early Inspection to chisel trajectory meant to: know whether is there any mistake of cutter motion know the error in CNC program know there is error in cliping All answers are acorrect

7. Early inspection to cutter trajectory conducted with:a. installed wor piece c. installed cutter b. un-installed work piece d. cutter and object installed strongly
