Objectives: Students will assimilate the knowledge necessary to operate CNC at a basic level.
Target audience: CNC operators (machining) in training or with a basic level of knowledge, technological engineers, staff interested in learning basic CNC knowledge
Duration: 5 days
Training agenda: Day 1 (theory and practical applications in the classroom) • Introduction • Analysis of the part execution drawing • Tolerances and deviations resulting from the execution drawing • Establishing the possibilities of execution of the parts in the given conditions • Possible variants of technological itinerary o 2D and 3D view in execution drawings o Plan projections o Sections in the piece • Choice of cutting tools for different types of parts o Choosing the necessary tool holders for processing o Choosing the type of pills / carbide and their geometry o Establishment of processing additions for operations and phases • Establishing the SDV list and the technological itinerary o Installation sketch o SDV List o Technological itinerary • Track program
Day 2 (applications on the machine in the work area) • Operating modes on numerically controlled machines o Manual mode with maintenance, with self-maintenance, the use of the crank, the incremental working mode o Semi-automatic mode (using MDI mode (manual data input) o Automatic mode Continuous, Phrase by phrase, DRY RUN Module, Simulations (extension checks) • Use of basic functions for use in manual and semi-automatic mode (MDI) o T tool call #### o tool change M6 o use of speed S ### o using the advance F #### o establishing the direction of M3 / M4 speed o starting / stopping the M8 / M9 coolant o setting the car's reference point (G53) o setting the part reference point (G54… G56) o establishing the number of machine origins and working variants
Day 3 • Exemplify the knowledge acquired in the last hours of day 2 • Turning technologies • Details with concrete exemplification on the car acquired on day 1 o an installation sketch, SDV list, technological itinerary, part program • Choice of cutting regimes
Day 4 (theory and practical applications in the gym and on the car) • Basic functions in the CNC program part (OSP300L) o linear and circular movements or timers o choice of tool T1… T32 ("tool") o choice of speed S5… S3000 ("speed") o choice of advance F0… F10000 ("feed") o determining the origin of the part G54 / G55 / G56 / G57 / G58 / G59 o establishing the x / z / C / B movement coordinates o auxiliary functions [M] M3 / M4 / M5 / M9 / M8 / o introduction of tools in the database o establishing tool corrections in the program (G41 / G42 / 43 / G48 / G49) o choice of work plans (G17 / G18 / G18) o entering the radius correction of the pill (r0.4… .r [n]) in the table o establishing the work area of the part o establishing safety plans o establishing the points of withdrawal / approach of the tool • Syntax of executing a program • Calling an existing program in memory • Insert a new program into memory • Modifying an existing program • Machine applications of these functions
Day 5 (applications on the machine in the work area) • Recapitulation of knowledge the day before • Choice of a piece by the customer • Establishing the execution steps of the part • Choice of cutting tools • Execution of the track program o piece execution o final measurements o analysis + optimization • Theoretical and practical examination
