Once again the Government has been too slow to act.” He said: “Plan B measures, such a mask-wearing and working from home, have been Labour’s plan all autumn. However, Labour’s Alex Norris MP, who represents Nottingham North, said the Government has not acted quick enough in response to the new strain. “There are clearly risks and there always will be risks for as long as there is Covid, but we can’t keep turning the taps on and off.” “I worry it’s a bit of a slippery slope. Precautions are one thing but when you start to restrict peoples’ freedoms, like with vaccine passports, you need pretty good data and evidence to support it. He said Omicron is doubling “every two to three days”, which is much faster than the previous Delta variant, with evidence in South Africa showing a big increase in hospital admissions once the new strain takes hold.īut Mr Bradley said: “I don’t see how you can justify restrictions ‘just in case’, and if that’s going to be your argument, how long does that go on for, and how many times do we go along this loop? This is despite Professor Chris Whitty, the country’s Chief Medical Officer, confirming there have been 568 cases of the Omicron variant and suggesting there will be a lag before it begins to impact hospitalisations. He believes there is no evidence to suggest the need for tighter restrictions in response to the Omicron variant, describing measures like vaccine passports and mandatory jabs as restricting “peoples’ freedoms”. Mr Bradley said he cannot support the measures. Mr Johnson also suggested there should be a “national conversation” about the introduction of compulsory vaccinations. There will also be daily tests for contacts of people with the Omicron variant, rather than isolation. You can leave the protective film on the bottom surface on the acrylic panel while cutting.They also mean a return of masks in most indoor public spaces including theatres and cinemas from Friday, and from Wednesday use of the NHS Covid Pass – proving vaccination status or a negative lateral flow test – for entry to venues such as nightclubs. Excess vibration can result in poor finish.ĩ. You need good suction on the CNC machine table to secure the acrylic parts. The idea is to get a good clean cut without melting the plastic as it’s being cut.Ĩ. The settings above are just a starting point. You need to run some test parts and find the optimal cutting feed rate and spindle speed for your machine. If you go faster than 18000 RPM you may have to increase the feed rate as well to prevent melting of the plastic.ħ.
The spindle speed (Rotation Per Minute) would be on the high end (18000 RPM). For an 1/2 bit you could try a feed rate of 200 inch per minute (5 meter per minute)Ħ. The feed rate would be slower than when you cut wood. A good rule to determine the cut depth, is to cut half of the tool diameter in a single pass (for a 1/2 bit you will have a 1/4 pass depth).ĥ. If you cut large panels, it’s better to use the largest diameter of bit possible to be able to cut deeper in a single pass and have a better finish. The O-Flute Bit is a good choice.įigure 3 -Example of a solid carbide O-Flute up shear bit for plasticsĤ. An up-shear tool is recommended for this type on material. You need to use a bit designed for acrylic cutting.
You’ll need to assign a tool to this material to make sure it doesn’t use the same tool as your typical wood panels.ģ. It’s really similar to a glass material in terms of finishes and texture.Ģ. In Cabinet Vision you create the acrylic as a Panel Stock material in the material manager.
