Pengertian mesin CNC
CNC singkatan dari Computer Numerically Controlled, merupakan mesin perkakas yang dilengkapi dengan sistem mekanik dan kontrol berbasis komputer yang mampu membaca instruksi kode N, G, F, T, dan lain-lain, dimana kode-kode tersebut akan menginstruksikan ke mesin CNC agar bekerja sesuai dengan program benda kerja yang akan dibuat. Secara umum cara kerja mesin perkakas CNC tidak berbeda dengan mesin perkakas konvensional. Fungsi CNC dalam hal ini lebih banyak menggantikan pekerjaan operator dalam mesin perkakas konvensional. Misalnya pekerjaan setting tool atau mengatur gerakan pahat sampai pada posisi siap memotong, gerakan pemotongan dan gerakan kembali keposisi awal, dan lain-lain. Demikian pula dengan pengaturan kondisi pemotongan (kecepatan potong, kecepatan makan dan kedalaman pemotongan) serta fungsi pengaturan yang lain seperti penggantian pahat, pengubahan transmisi daya (jumlah putaran poros utama), dan arah putaran poros utama, pengekleman, pengaturan cairan pendingin dan sebagainya. Mesin perkakas CNC dilengkapi dengan berbagai alat potong yang dapat membuat benda kerja secara presisi dan dapat melakukan interpolasi yang diarahkan secara numerik (berdasarkan angka). Parameter sistem operasi CNC dapat diubah melalui program perangkat lunak (software load program) yang sesuai. Tingkat ketelitian mesin CNC lebih akurat hingga ketelitian seperseribu millimeter, karena penggunaan ballscrew pada setiap poros transportiernya. Ballscrew bekerja seperti lager yang tidak memiliki kelonggaran/spelling namun dapat bergerak dengan lancar. Pada awalnya mesin CNC masih menggunakan memori berupa kertas berlubang sebagai media untuk mentransfer kode G dan M ke sistem kontrol. Setelah tahun 1950, ditemukan metode baru mentransfer data dengan menggunakan kabel RS232, floppy disks, dan terakhir oleh Komputer Jaringan Kabel

(Computer Network Cables) bahkan bisa dikendalikan melalui internet. Akhir-akhir ini mesin-mesin CNC telah berkembang secara menakjubkan sehingga telah mengubah industri pabrik yang selama ini menggunakan tenaga manusia menjadi mesin-mesom otomatik. Dengan telah berkembangnya Mesin CNC, maka benda kerja yang rumit sekalipun dapat dibuat secara mudah dalam jumlah yang banyak. Selama ini pembuatan komponen/suku cadang suatu mesin yang presisi dengan mesin perkakas manual tidaklah mudah, meskipun dilakukan oleh seorang operator mesin perkakas yang mahir sekalipun. Penyelesaiannya memerlukan waktu lama. Bila ada permintaan konsumen untuk membuat komponen dalam jumlah banyak dengan waktu singkat, dengan kualitas sama baiknya, tentu akan sulit dipenuhi bila menggunakan perkakas manual. Apalagi bila bentuk benda kerja yang dipesan lebih rumit, tidak dapat diselesaikan dalam waktu singkat. Secara ekonomis biaya produknya akan menjadi mahal, hingga sulit bersaing dengan harga di pasaran. Tuntutan konsumen yang menghendaki kualitas benda kerja yang presisi, berkualitas sama baiknya, dalam waktu singkat dan dalam jumlah yang banyak, akan lebih mudah dikerjakan dengan mesin perkakas CNC (Computer Numerlcally Controlled), yaitu mesin yang dapat bekerja melalui pemogramman yang dilakukan dan dikendalikan melalui komputer. Mesin CNC dapat bekerja secara otomatis atau semiotomatis setelah diprogram terlebih dahulu melalui komputer yang ada. Program yang dimaksud merupakan program membuat benda kerja yang telah direncanakan atau dirancang sebelumnya. Sebelum benda kerja tersebut dieksikusi atau dikerjakan oleh mesin CNC, sebaikanya program tersebut di cek berulang-ualang agar program benarbenar telah sesuai dengan bentuk benda kerja yang diinginkan, serta benar-benar dapat dikerjakan oleh mesin CNC. Pengecekan tersebut dapat melalui layar monitor yang terdapat pada mesin atau bila tidak ada fasilitas cheking melalui monitor (seperti pada CNC TU EMCO 2A/3A) dapat pula melalui plotter yang dipasang pada tempat dudukan pahat/palsu frais. Setelah program benar-benar telah berjalan seperti rencana, baru kemudian dilaksanakan/dieksekusi oleh mesin CNC. Dari segi pemanfaatannya, mesin perkakas CNC dapat dibagi menjadi dua, antara lain: (a) mesin CNC Training unit (TU), yaitu mesin yang digunakan sarana pendidikan, dosen dan training. (b) mesin CNC produktion unit (PU), yaitu mesin CNC yang digunakan untuk membuat benda kerja/komponen yang dapat digunakan sebagai mana mestinya. Dari segi jenisnya, mesin perkakas CNC dapat dibagi menjadi tiga jenis, antara lain: (a) mesin CNC 2A yaitu mesin CNC 2 aksis, karena gerak pahatnya hanya pada arah dua sumbu koordinat (aksis) yaitu koordinat X, dan koordinat Z, atau dikenal dengan mesin bubut CNC, (b) mesin CNC 3A, yaitu mesin CNC 3 aksis atau mesin yang memiliki gerakan sumbu utama kearah sumbu koordinat X, Y, dan Z, atau dikenal dengan mesin frsais CNC. (c) mesin CNC kombinasi, yaitu mesin CNC yang mampu mengerjakan pekerjaan bubut dan freis sekaligus, dapat pula dilengkapi dengan peralatan pengukuran sehingga dapat melakukan pengontrolan kualitas pembubutan/pengefraisan pada benda kerja yang dihasilkan. Pada umumnya mesin CNC yang sering dijumpai adalah mesin CNC 2A (bubut) dan mesin CNC 3A (frais).

As he reflected on the festering wounds deepened by race and grievance that have been on painful display in America’s cities lately, President Obama on Monday found himself thinking about a young man he had just met named Malachi.

A few minutes before, in a closed-door round-table discussion at Lehman College in the Bronx, Mr. Obama had asked a group of black and Hispanic students from disadvantaged backgrounds what could be done to help them reach their goals. Several talked about counseling and guidance programs.

“Malachi, he just talked about — we should talk about love,” Mr. Obama told a crowd afterward, drifting away from his prepared remarks. “Because Malachi and I shared the fact that our dad wasn’t around and that sometimes we wondered why he wasn’t around and what had happened. But really, that’s what this comes down to is: Do we love these kids?”

Many presidents have governed during times of racial tension, but Mr. Obama is the first to see in the mirror a face that looks like those on the other side of history’s ledger. While his first term was consumed with the economy, war and health care, his second keeps coming back to the societal divide that was not bridged by his election. A president who eschewed focusing on race now seems to have found his voice again as he thinks about how to use his remaining time in office and beyond.

Obama Speaks of a ‘Sense of Unfairness’

Obama Speaks of a ‘Sense of Unfairness’

At an event announcing the creation of a nonprofit focusing on young minority men, President Obama talked about the underlying reasons for recent protests in Baltimore and other cities.

In the aftermath of racially charged unrest in places like Baltimore, Ferguson, Mo., and New York, Mr. Obama came to the Bronx on Monday for the announcement of a new nonprofit organization that is being spun off from his White House initiative called My Brother’s Keeper. Staked by more than $80 million in commitments from corporations and other donors, the new group, My Brother’s Keeper Alliance, will in effect provide the nucleus for Mr. Obama’s post-presidency, which will begin in January 2017.

“This will remain a mission for me and for Michelle not just for the rest of my presidency but for the rest of my life,” Mr. Obama said. “And the reason is simple,” he added. Referring to some of the youths he had just met, he said: “We see ourselves in these young men. I grew up without a dad. I grew up lost sometimes and adrift, not having a sense of a clear path. The only difference between me and a lot of other young men in this neighborhood and all across the country is that I grew up in an environment that was a little more forgiving.”

Organizers said the new alliance already had financial pledges from companies like American Express, Deloitte, Discovery Communications and News Corporation. The money will be used to help companies address obstacles facing young black and Hispanic men, provide grants to programs for disadvantaged youths, and help communities aid their populations.

Joe Echevarria, a former chief executive of Deloitte, the accounting and consulting firm, will lead the alliance, and among those on its leadership team or advisory group are executives at PepsiCo, News Corporation, Sprint, BET and Prudential Group Insurance; former Secretary of State Colin L. Powell; Senator Cory Booker, Democrat of New Jersey; former Attorney General Eric H. Holder Jr.; the music star John Legend; the retired athletes Alonzo Mourning, Jerome Bettis and Shaquille O’Neal; and the mayors of Indianapolis, Sacramento and Philadelphia.

The alliance, while nominally independent of the White House, may face some of the same questions confronting former Secretary of State Hillary Rodham Clinton as she begins another presidential campaign. Some of those donating to the alliance may have interests in government action, and skeptics may wonder whether they are trying to curry favor with the president by contributing.

“The Obama administration will have no role in deciding how donations are screened and what criteria they’ll set at the alliance for donor policies, because it’s an entirely separate entity,” Josh Earnest, the White House press secretary, told reporters on Air Force One en route to New York. But he added, “I’m confident that the members of the board are well aware of the president’s commitment to transparency.”

The alliance was in the works before the disturbances last week after the death of Freddie Gray, the black man who suffered fatal injuries while in police custody in Baltimore, but it reflected the evolution of Mr. Obama’s presidency. For him, in a way, it is coming back to issues that animated him as a young community organizer and politician. It was his own struggle with race and identity, captured in his youthful memoir, “Dreams From My Father,” that stood him apart from other presidential aspirants.

But that was a side of him that he kept largely to himself through the first years of his presidency while he focused on other priorities like turning the economy around, expanding government-subsidized health care and avoiding electoral land mines en route to re-election.

After securing a second term, Mr. Obama appeared more emboldened. Just a month after his 2013 inauguration, he talked passionately about opportunity and race with a group of teenage boys in Chicago, a moment aides point to as perhaps the first time he had spoken about these issues in such a personal, powerful way as president. A few months later, he publicly lamented the death of Trayvon Martin, a black Florida teenager, saying that “could have been me 35 years ago.”

That case, along with public ruptures of anger over police shootings in Ferguson and elsewhere, have pushed the issue of race and law enforcement onto the public agenda. Aides said they imagined that with his presidency in its final stages, Mr. Obama might be thinking more about what comes next and causes he can advance as a private citizen.

That is not to say that his public discussion of these issues has been universally welcomed. Some conservatives said he had made matters worse by seeming in their view to blame police officers in some of the disputed cases.

“President Obama, when he was elected, could have been a unifying leader,” Senator Ted Cruz of Texas, a Republican candidate for president, said at a forum last week. “He has made decisions that I think have inflamed racial tensions.”

On the other side of the ideological spectrum, some liberal African-American activists have complained that Mr. Obama has not done enough to help downtrodden communities. While he is speaking out more, these critics argue, he has hardly used the power of the presidency to make the sort of radical change they say is necessary.

The line Mr. Obama has tried to straddle has been a serrated one. He condemns police brutality as he defends most officers as honorable. He condemns “criminals and thugs” who looted in Baltimore while expressing empathy with those trapped in a cycle of poverty and hopelessness.

In the Bronx on Monday, Mr. Obama bemoaned the death of Brian Moore, a plainclothes New York police officer who had died earlier in the day after being shot in the head Saturday on a Queens street. Most police officers are “good and honest and fair and care deeply about their communities,” even as they put their lives on the line, Mr. Obama said.

“Which is why in addressing the issues in Baltimore or Ferguson or New York, the point I made was that if we’re just looking at policing, we’re looking at it too narrowly,” he added. “If we ask the police to simply contain and control problems that we ourselves have been unwilling to invest and solve, that’s not fair to the communities, it’s not fair to the police.”

Moreover, if society writes off some people, he said, “that’s not the kind of country I want to live in; that’s not what America is about.”

His message to young men like Malachi Hernandez, who attends Boston Latin Academy in Massachusetts, is not to give up.

“I want you to know you matter,” he said. “You matter to us.”
