CNC_NP1 is_VBZ an_AT1 abbreviation_NN1 for_IF computer_NN1 numerical_JJ control_NN1 ._. 
A_ZZ1 CNC_NP1 machine_NN1 ,_, then_RT ,_, is_VBZ a_AT1 machine_NN1 that_CST carves_VVZ out_RP objects_NN2 in_II three_MC dimensions_NN2 from_II a_AT1 solid_JJ block_NN1 of_IO material_NN1 ._. 
CNC_NP1 machines_NN2 are_VBR commonly_RR used_VVN in_II industry_NN1 to_TO produce_VVI small_JJ parts_NN2 such_II21 as_II22 bicycle_NN1 stems_NN2 and_CC tools_NN2 ._. 
Low-cost_JJ CNC_NP1 machines_NN2 are_VBR increasingly_RR used_VVN by_II serious_JJ hobbyists_NN2 ,_, especially_RR woodworkers_NN2 ,_, to_TO carve_VVI creations_NN2 out_II21 of_II22 materials_NN2 such_II21 as_II22 wood_NN1 and_CC aluminum_NN1 ._. 
Read_VV0 through_II this_DD1 chapter_NN1 and_CC then_RT flip_VV0 through_II the_AT rest_NN1 of_IO the_AT book_NN1 --_NN1 you_PPY 'll_VM start_VVI seeing_VVG pictures_NN2 of_IO an_AT1 unusual_JJ device_NN1 being_VBG built_VVN (_( beginning_VVG with_IW Chapter_NN1 7_MC and_CC ending_VVG with_IW Chapter_NN1 17_MC )_) ._. 
That_DD1 device_NN1 is_VBZ the_AT do-it-yourself_NN1 (_( DIY_NN1 )_) CNC_NP1 machine_NN1 ._. 
The_AT DIY_NN1 part_NN1 is_VBZ because_CS you_PPY 're_VBR going_VVGK to_TO learn_VVI how_RRQ to_TO build_VVI one_PN1 in_II this_DD1 book_NN1 ._. 
When_CS you_PPY 're_VBR done_VDN ,_, you_PPY 'll_VM be_VBI the_AT proud_JJ owner_NN1 of_IO a_AT1 three-dimensional_JJ carving_NN1 machine_NN1 that_CST can_VM fabricate_VVI parts_NN2 and_CC objects_NN2 from_II soft_JJ materials_NN2 such_II21 as_II22 wood_NN1 ,_, plastics_NN2 ,_, and_CC even_RR aluminum_NN1 ._. 
What_DDQ is_VBZ CNC_NP1 ?_? 
Computer_NN1 numerical_JJ control_NN1 is_VBZ a_AT1 very_RG broad_JJ term_NN1 that_CST encompasses_VVZ a_AT1 variety_NN1 of_IO types_NN2 of_IO machines_NN2 --_NN1 all_RR with_IW different_JJ sizes_NN2 ,_, shapes_NN2 ,_, and_CC functions_NN2 ._. 
But_CCB the_AT easiest_JJT way_NN1 to_TO think_VVI about_II CNC_NP1 is_VBZ to_TO simply_RR understand_VVI that_CST it_PPH1 's_VBZ all_DB about_II using_VVG a_AT1 computer_NN1 as_II a_AT1 means_NN to_TO control_VVI a_AT1 machine_NN1 that_CST carves_VVZ useful_JJ objects_NN2 from_II solid_JJ blocks_NN2 of_IO material_NN1 ._. 
For_REX21 example_REX22 ,_, a_AT1 CNC_NP1 machine_NN1 might_VM begin_VVI with_IW a_AT1 solid_JJ block_NN1 of_IO aluminum_NN1 ,_, and_CC then_RT carve_VV0 away_RL just_RR the_AT right_JJ material_NN1 to_TO leave_VVI you_PPY with_IW a_AT1 bicycle_NN1 brake_NN1 handle_NN1 ._. 
CNC_NP1 machines_NN2 can_VM be_VBI divided_VVN into_II two_MC groups_NN2 :_: turning_VVG machines_NN2 and_CC milling_NN1 machines_NN2 ._. 
A_AT1 turning_JJ machine_NN1 is_VBZ generally_RR made_VVN up_RP of_IO a_AT1 device_NN1 that_CST spins_VVZ a_AT1 workpiece_NN1 at_II high_JJ speed_NN1 and_CC a_AT1 tool_NN1 (_( sharp_JJ edge_NN1 )_) that_CST shaves_VVZ off_II the_AT undesired_JJ material_NN1 from_II the_AT workpiece_NN1 (_( where_CS the_AT tool_NN1 is_VBZ moved_VVN back_RP and_CC forth_RR and_CC in_RP and_CC out_RP until_CS the_AT desired_JJ form_NN1 is_VBZ achieved_VVN )_) ._. 
A_AT1 milling_NN1 machine_NN1 is_VBZ a_AT1 machine_NN1 that_CST has_VHZ a_AT1 spindle_NN1 (_( a_AT1 device_NN1 similar_JJ to_II a_AT1 router_NN1 )_) with_IW a_AT1 special_JJ tool_NN1 that_CST spins_VVZ and_CC cuts_VVZ in_II various_JJ directions_NN2 and_CC moves_VVZ in_II three_MC different_JJ directions_NN2 along_II the_AT x_ZZ1 ,_, y_ZZ1 ,_, and_CC z_ZZ1 axes_NN2 ._. 
Historically_RR ,_, you_PPY would_VM n't_XX actually_RR need_VVI a_AT1 computer_NN1 to_TO create_VVI forms_NN2 with_IW a_AT1 turning_JJ machine_NN1 or_CC a_AT1 milling_NN1 machine_NN1 ._. 
Adding_VVG a_AT1 computer_NN1 to_II the_AT mix_NN1 allows_VVZ you_PPY to_TO design_VVI a_AT1 product_NN1 on_II a_AT1 computer_NN1 first_MD and_CC then_RT specify_VV0 how_RRQ the_AT machine_NN1 should_VM cut_VVI this_DD1 product_NN1 ._. 
To_TO design_VVI the_AT product_NN1 is_VBZ to_TO produce_VVI a_AT1 computer-aided_JJ design_NN1 (_( CAD_NN1 )_) file_NN1 ._. 
Then_RT you_PPY specify_VV0 how_RRQ the_AT machine_NN1 should_VM cut_VVI the_AT product_NN1 ,_, and_CC the_AT result_NN1 of_IO that_DD1 step_NN1 is_VBZ a_AT1 computer-aided_JJ manufacturing_NN1 (_( CAM_NP1 )_) file_NN1 (_( or_CC G-Code_NP1 file_NN1 ,_, or_CC ._. 
NC_NP1 file_NN1 --_NN1 there_EX are_VBR many_DA2 names_NN2 for_IF this_DD1 type_NN1 of_IO file_NN1 )_) ._. 
This_DD1 CAM_NN1 file_NN1 remembers_VVZ all_DB of_IO the_AT operations_NN2 that_CST the_AT milling_NN1 machine_NN1 must_VM follow_VVI to_TO cut_VVI out_RP the_AT parts_NN2 for_IF the_AT product_NN1 ._. 
The_AT computer_NN1 tells_VVZ the_AT CNC_NP1 machine_VV0 how_RRQ to_TO build_VVI the_AT part_NN1 by_II interpreting_VVG the_AT CAM_NN1 file_NN1 into_II signals_NN2 that_CST the_AT CNC_NP1 machine_NN1 can_VM understand_VVI ._. 
Industrial_JJ Uses_NN2 Industrial_JJ applications_NN2 for_IF CNC_NP1 machines_NN2 have_VH0 been_VBN chiefly_RR based_VVN around_II the_AT removal_NN1 of_IO metal_NN1 to_TO create_VVI a_AT1 desired_JJ form_NN1 ._. 
Metal_NN1 is_VBZ widely_RR used_VVN for_IF producing_VVG almost_RR everything_PN1 we_PPIS2 see_VV0 around_II us_PPIO2 ,_, even_CS21 though_CS22 these_DD2 things_NN2 may_VM not_XX be_VBI made_VVN of_IO metal_NN1 themselves_PPX2 ._. 
Some_DD of_IO the_AT most_RGT obvious_JJ products_NN2 that_CST are_VBR made_VVN of_IO metal_NN1 are_VBR cars_NN2 ._. 
The_AT engine_NN1 block_NN1 and_CC the_AT parts_NN2 within_II the_AT transmission_NN1 are_VBR directly_RR produced_VVN from_II a_AT1 CNC_NP1 machine_NN1 because_CS tight_JJ tolerances_NN2 are_VBR necessary_JJ (_( a_AT1 tolerance_NN1 is_VBZ a_AT1 range_NN1 in_II dimensioning_VVG to_II which_DDQ the_AT machine_NN1 must_VM adhere_VVI )_) ._. 
However_RR ,_, most_DAT of_IO the_AT parts_NN2 of_IO a_AT1 car_NN1 are_VBR not_XX made_VVN by_II a_AT1 CNC_NP1 machine_NN1 ,_, but_CCB they_PPHS2 have_VH0 a_AT1 latent_JJ connection_NN1 to_II one_PN1 ._. 
For_REX21 example_REX22 ,_, how_RRQ do_VD0 you_PPY make_VVI a_AT1 quarter_NN1 panel_NN1 ?_? 
There_EX is_VBZ a_AT1 hydraulic_JJ press_NN1 with_IW a_AT1 thing_NN1 called_VVN a_AT1 die_VV0 to_TO create_VVI an_AT1 impression_NN1 in_II a_AT1 sheet_NN1 of_IO metal_NN1 ._. 
Most_DAT of_IO the_AT parts_NN2 of_IO the_AT hydraulic_JJ press_NN1 were_VBDR made_VVN from_II a_AT1 CNC_NP1 machine_NN1 ._. 
The_AT die_NN1 ,_, the_AT part_NN1 that_CST carries_VVZ the_AT negative_JJ form_NN1 of_IO the_AT quarter_NN1 panel_NN1 and_CC that_DD1 can_VM be_VBI replaced_VVN when_CS design_NN1 changes_NN2 ,_, was_VBDZ also_RR made_VVN by_II a_AT1 CNC_NP1 machine_NN1 ,_, and_CC then_RT tempered_VVN for_IF hardening_VVG and_CC heat_NN1 resistance_NN1 ._. 
Even_RR the_AT plastic_NN1 parts_NN2 of_IO a_AT1 car_NN1 have_VH0 some_DD connection_NN1 to_II a_AT1 CNC_NP1 machine_NN1 ._. 
Many_DA2 of_IO these_DD2 parts_NN2 were_VBDR made_VVN from_II a_AT1 mold_NN1 that_CST was_VBDZ created_VVN using_VVG a_AT1 CNC_NP1 machine_NN1 ._. 
Because_CS CNC_NP1 machines_NN2 have_VH0 very_RG high_JJ precision_NN1 and_CC they_PPHS2 can_VM provide_VVI information_NN1 back_RP to_II the_AT computer_NN1 ,_, they_PPHS2 are_VBR also_RR used_VVN in_II dimensional_JJ testing_NN1 ._.
