ping the cad cam application unisurf in the 1960s for car body design and tooling at renault 13 alexander hammer at delaval steam turbine company invented a technique to progressively drill turbine blades out of a solid block of metal with the drill controlled by a punch card reader in 1950 boeing first obtained nc machines in 1956 made by companies such as kearney and trecker stromberg carlson and thompson ramo wooldridge 14 historically cam software was seen to have several shortcomings that necessitated an overly high level of involvement by skilled cnc machinists cam software would output code for the least capable machine as each machine tool control added on to the standard g code set for increased flexibility in some cases such as improperly set up cam software or specific tools the cnc machine required manual editing before the program will run properly none of these issues were so insurmountable that a thoughtful engineer or skilled machine operator could not overcome for prototyping or small production runs g code is a simple language in high production or high precision shops a different set of problems were encountered where an experienced cnc machinist must both hand code programs and run cam software the integration of cad with other components of cad cam cae product lifecycle management plm environment requires an effective cad data exchange usually it had been necessary to force the cad operator to export the data in one of the common data formats such as iges or stl or parasolid formats that are supported by a wide variety of software the output from the cam software is usually a simple text file of g code m codes sometimes many thousands of commands long that is then transferred to a machine tool using a direct numerical control dnc program or in modern controllers using a common usb storage device cam packages could not and still cannot reason as a machinist can they could not optimize toolpaths to the extent required of mass production users would select the type of tool machining process and paths to be used while an engineer may have a working knowledge of g code programming small optimization and wear issues compound over time mass produced items that require machining are often initially created through casting or some other non machine method this enables hand written short and highly optimized g code that could not be produced in a cam package at least in the united states there is a shortage of young skilled machinists entering the workforce able to perform at the extremes of manufacturing high precision and mass production 15 16 as cam software and machines become more complicated the skills required of a machinist or machine operator advance to approach that of a computer programmer and engineer rather than eliminating the cnc machinist from the workforce typical areas of concern high speed machining including streamlining of tool paths multi function machining 5 axis machining feature recognition and machining automation of machining processes ease of use overcoming historical shortcomings edit over time the historical shortcomings of cam are being attenuated both by providers of niche solutions and by providers of high end solutions this is occurring primarily in three arenas ease of usage manufacturing complexity integration with plm and the extended enterprise 17 ease in use for the user who is just getting started as a cam user out of the box capabilities providing process wizards templates libraries machine tool kits automated feature based machining and job function specific tailorable user interfaces build user confidence and speed the learning curve user confidence is further built on 3d visualization through a closer integration with the 3d cad environment including error avoiding simulations and optimizations manufacturing complexity the manufacturing environment is increasingly complex the need for cam and plm tools by the manufacturing engineer nc programmer or machinist is similar to the need for computer assistance by the pilot of modern aircraft systems the modern machinery cannot be properly used without this assistance today s cam systems support the full range of machine tools including turning 5 axis machining waterjet laser plasma cutting and wire edm today s cam user can easily generate streamlined tool paths optimized tool axis tilt for higher feed rates better tool life and surface finish and ideal cutting depth in addition to programming cutting operations modern cam software can also drive non cutting operations such as machine tool probing integration with plm and the extended enterprise lm to integrate manufacturing with enterprise operations from concept through field support of the finished product to ensure ease of use appropriate to user objectives modern cam solutions are scalable from a stand alone cam system to a fully integrated multi cad 3d solution set these solutions are created to meet the full needs of manufacturing personnel including part planning shop documentation resource management and data management and exchange to prevent these solutions from detailed tool specific information a dedicated tool management machining process edit most machining progresses through many stages 18 each of which is implemented by a variety of basic and sophisticated strategies depending on the part design material and software available roughing this process usually begins with raw stock known as billet or a rough casting which a cnc machine cuts roughly to shape of the final model ignoring the fine details in milling the result often gives the appearance of terraces or steps because the strategy has taken multiple steps down the part as it removes material this takes the best advantage of the machine s ability by cutting material horizontally common strategies are zig zag clearing offset clearing plunge roughing rest roughing and trochoidal milling adaptive clearing the goal at this stage is to remove the most material in the least time without much concern for overall dimensional accuracy when roughing a part a small amount of extra material is purposely left behind to be removed in subsequent finishing operation s semi finishing this process begins with a roughed part that unevenly approximates the model and cuts to within a fixed offset distance from the model the semi finishing pass must leave a small amount of material called the scallop so the tool can cut accurately but not so little that the tool and material deflect away from the cutting surfaces 19 common strategies are raster passes waterline passes constant step over passes and pencil milling finishing finishing involves many light passes across the material in fine steps to produce the finished part when finishing a part the steps between passes is minimal to prevent tool deflection and material spring back in order to reduce the lateral tool load tool engagement is reduced while feed rates and spindle speeds are generally increased in order to maintain a target surface speed sfm a light chip load at high feed and rpm is often referred to as high speed machining hsm and can provide quick machining times with high quality results 20 the result of these lighter passes is a highly accurate part with a uniformly high surface finish in addition to modifying speeds and feeds machinists will often have finishing specific endmills which never used as roughing endmills this is done to protect the endmill from developing chips and flaws in the cutting surface which would leave streaks and blemishes on the final part contour milling in milling applications on hardware with rotary table and or rotary head axes a separate finishing process called contouring can be performed instead of stepping down in fine grained increments to approximate a surface the work piece or tool is rotated to make the cutting surfaces of the tool tangent to the ideal part features this produces an excellent surface finish with high dimensional accuracy this process is commonly used to machine complex organic shapes such as turbine and impeller blades which due to their complex curves and overlapping geometry are impossible to machine with only three axis machines 21 software large vendors edit see also list of computer aided manufacturing cam software and category computer aided
