Awesome

Amazing app

Добавьте пожалуйста

Хотелось бы видеть в программе расфрезеровеу отверстий через интерполяцию g12.1 на токарном с осью С. Или возможность фрезерования по контуру на токарном в полярных координатах. Хотелось бы еще добавить функционал cncstapeer free. Или xc cnc. Купил бы сразу если бы можно было быстро прописать g код для фрезеровки лысок. Отверстий или граней.

Отличный калькулятор, аналогов на IOS просто нет.

Работа связана с ЧПУ, приложение очень выручает, спасибо разработчику.

Great but

Great with so many features, but subscription is a big disappointment. I understand the reason but would like the option even if more expensive.

Subscription only

This should be a one time purchase not a monthly or yearly subscription. Will not be getting.
